how does an eccentric oil pump work

The idea behind this pump is different pressure zones (or volume changes)

In this pump there are only 2 moving parts, the red rotor which spins by the engine power (either by a little metal chain or sprockets), it moves the passive yellow rotor.

This movement causes CONSTANT VOLUME CHANGES in certain areas of the pump. At the left you can see the empty space (which is shown as stripes) always expanding - exactly there you will find the oil entrance to the pump.

On the right side you will see the space is constantly getting smaller - there is the oil exit pipe located.

The oil is sucked-in on the left, it is then carried in the space between the two rotors, and then finally being squeezed out on the right side exit.

A more clearer flash movie of the pump is here: http://www.motoetc.com/home/2010/03/eccentric-oil-pump/

I've got these in my MGs, when my MGA engine self destructed at 100mph on the M3 it was the only component still salvageable

motordan tahrik alan saft hangisine bağlı?

[golbis]

on some scooters this pump is moved by a little metal chain that is attached to the crankshaft. on motorcycles it moves by a sprocket attached to to a moving part, like the clutch or magneto or whatever

the written explanation was extremely helpful, thank you!

nice job

some one should make a new Wankel rotary engine out of this technology

[GSpotter63]

I have been working on a similar design now for a few years. I use rotating valve holes as well.

[jallaguri]

Let diesel and air mixture enter the pump, and let it be compressed to ignition point at the bottom of the wheel. Use valves to control inlet and exhaust. This should work well as a true none eccentric rotary engine - even better than the conventional rotary engine as we know it?

THANKS FOR SHARING..CIAOOO

I wonder if this would work as a motor? With some modification it might work as a rotary engine.
