Rotary compressor operating as an air motor

I was thinking about the reason why these rotary compressors have reed valves on the output when theoretically they shouldn't be needed, and after a quick test with an air compressor, it's quite apparent why: Without the valve, the high discharge pressure would turn the compressor into a motor, and would spin it up to high speed in reverse, potentially damaging the motor or compressor.

does it always turn in the same direction or can you switch it from counter clock wise to clockwise??

@vaticinus If you removed the one way valve on the output and connected tubes to both intake and output, you could run both ways by reversing the air flow. There will still be positions that it won't start from though.

This sounds hilarious..

Hi!! I´m searching the rpm of this compressor, could you help me?? and why not some rules for regulates this rpm. Thanks!

sounds like it should be making bubbles

@hhohydrogen

Yes, and you can use water as fuel too.

can i use my ac compressor as a supercharger into the intake for boost??

I guess if you remove the discharge valves and open up the ports to the same size as the inlet with a die grinder it would work as a good hydraulic motor, or vice versa, an oil pump!

lubrication wouldn't be a problem at all.

ya i assumend the capacity or cfm would be crazy say 200 or so to run it but i wonder if oil could be used in place of air

this would drasticly improve the turbine efficiancy i know its not a turbine but its a standerd rule that slow moving heavy fluid is far more efficiant then high volocity

gases as a power transfer medien this would require you to bore out the intake maybe ,one day i may fill a compressore tank halve full of oil andpressure it up the oil could discharge into another .....

I tried it last night with that big Mitsubishi I had in my disassembly video wit the valves in and it works okay, but theirs next to no torque, unless of course you can feed it a continuous 3/4" 200 psi line. but that's a lot of liters per min of air!

lubircation is a major issue too, you'd have to press off the motor rotor and house the pump in a new oil filled housing with just the shaft sticking out.
