meter in circuits so then we will go by the working of this so here the tank that is the storage tank then it comes to the cell this has a pump the whatever the oil is going to be pumping in the upward direction if there is a pressure is more than the designed or defined pressure so then it will be through this relief valve it come come back to the tank so while it is going in the upward direction so here there is a directional control valve so in this direction control valve we are going to be calling this as a 4 by 3 means 4 ports and 3 controls so here whenever you are going to be operating this knob so through that one we can have the control of this one the middle one is related with the normal flow so means in this middle one whatever the flow is going to be through this way it will come back to the once again to the storage tank so here we are just in this diagram we are connected this one as for the flow in the upward direction and that flow is coming through this one so means we are going to be calling it as 4 ports and 3 positions so that is what it is a 4 by 3 directional control valve the first one is related with the ports 1 2 3 4 ports and the second one is related with as a 3 positions we can change this position of this directional control valve so through this then it the flow is going to be taken this one as flow control valve so where it is a flow control valve so here this is restricted there is no flow through this particular direction only flow is going to be through this way so then this flow is going to be controlled here and this one you are going to be considering the cylinder and piston arrangement so where this is a load is provided on this particularly this one means the total working of the system this one is load is coming through this particular way so the outlet of this one is once again it is flowing through this particular way and here it is a flow is going to be taken place and this is restricted now this is restricted so here the flow is going to be taken place through this way it will come back to the storage tank so means from the source pump then directional control valve and then the flow control valve then it comes to the piston and cylinder arrangement so here we will go with the this radical indicating it as a high pressure oil is going to be flowing through this way so oil is going to be pumped from the tank so that is a pressure compensated pump so here this oil is coming through this particular way because we are adjusted this three slots we can adjust any one of this one depending upon the requirement this is normal condition this is normal one and this is we can have the reverse direction and this is a regular direction so here this will come through this way so when the flow is going to be taken place through this way because we can control this one this is controlling nothing but this we can control it so this is controlling nothing but this one so whatever the defined after regulating this one while we are going to be sending this high pressure oil through this one so here the loading whatever the load is acting on this particularly area so that is going to be pushing it backside so this is going to be pushing it backside so then this side whatever the oil is available on the backside of the piston that oil is coming through this way and it will come here so here the flow control wall is now opened here so through this way the oil is going to be coming through this one and through the directional control wall it come back to the storage tank so here this is not in active condition so actually the meter in flow control means whatever the oil is going to be supplying to this particularly cylinder the inlet is going to be controlled here means this is what we are going to be calling it as a meter in flow control so means the oil is coming through this way and it will go to this one means inlet is going to be controlled here so this portion is going to be controlled for inlet we are not going to be controlling this one we are going to be controlling only inlet side so I am explaining the related with as a inlet to this one the same thing we are going to be applying the concept for this also in the next diagram we are going to be applying the same concept by changing the position of this one so in this totally we are going to be understanding as the high pressure oil is coming through this way and this is direction control wall then it will come to this one as a flow control wall so through this way it will come to the piston cylinder arrangement and piston is going to be pushing back side and because of that whatever the oil is available here it will come through this way and it will directly flow to the reservoir this is one type we are going to be studying and another one is we are going to be changing the position that is a four by three wall we are going to be changing the position of the wall so here in the previous diagram this is controlled in this diagram this what we are going to be controlling it so here the flow whatever it is coming so just change the position of this one the previous diagram the position is this one now we are going to be shifted this one to the this side so now you have shifted this one it is a reverse direction you are applying means inlet is going to be in the backside of the piston inlet is going to be the backside of the piston so now the flow is going to be taken place once again the motor is going to be operated and the high pressure oil is flowing through this way and it will come to this one so now this is not in this is not allowing the this oil to flow this side it is a close now so this oil is going to be flowing through this way controlled wall flow control so this way it will come to this one means it is going to be pushing it back to the original position so this is going to be pushing it back so in this case this is going to be the piston is going to be moving in this direction so while it is moving in this direction so that time whatever the oil is available here it will come through this way so now in this important thing is so this is not in working condition this is not in working condition now so this is flow is going to be flowing through this way and it will come back to the this and here the connection is given to is the reverse direction that will come back to the reservoir tank so here once again we are going to be controlling inlet controlling in that side in the previously controlling here also inlet so here the miter inflow is nothing but we are going to be controlling whatever the oil is going to be flowing inside the piston either it is in the front side or it is in the back side the reverse of this one you are going with the next as miter out system so here once again the working of this one you are going to be understanding with the next this clip the working model of miter in circuit here you can observe it so the oil is going to be flowing this way this path is going to be taken place and through this one it will come to this one and here it is not allowing to flow so here this is a high pressure oil is going to flowing through this flow control wall so then it will come to this one this is going to be repeated so now the oil is going to be flowing in this way so it is reversed means it is we have shifted to the another side out of these three control so flowing this way and load is coming this side and this one outlet it will come through this way it is once again I will repeat the same thing flowing taking place like this the control is going to be taken place inlet miter in so that will come here the outlet is coming through this way without any resistance it will flow back to the reservoir here it is come to act to the reservoir hero mark is indicating the flow and red color indicating as a high pressure and here blue color is back to the reservoir the same thing we have shifted this one next in this shift shifted to the reverse direction so now the flow is going to be taking place through this way and it will come to the backside of the piston now it is moving in the forward direction at the same time this flow is in the normal condition it is coming back to the reservoir through this one it will come back to the reservoir so just it is for the working model the miter in circuits so just let me know the what are the application of miter in circuits what are the application of miter in circuits so here one thing you understand as what exactly the flowing is going to be taken place inside by that one utilization how exactly you are going to be considering it as a working and that applications what are the application of miter in circuits a miter in circuit is ideal in application where a load always offers a positive resistance to flow during a control stroke positive resistance to flow during a control stroke just you see this line as a positive resistance to flow during a control stroke okay this is what you are observed in the diagram also so here the examples would be feeding grinder tables welding machines milling machines and rotary hydraulic motor drives so here once again just this is a line i'm i'm explained because of positive resistance to flow during a control stroke so just you can observe it this is a positive resistance to flow during this control this is what we are explained there in that particular diagram so here for this further details you may refer this particular site even as a oil hydraulic system
