chrysler a/c compressor as air compressor

Rotary screw compressors do this, but they run a pretty strong oil mist to cool and lube the compressor rotors and housing. No reason you couldn't do the same.

York compressors are commonly used as air compressors. See

Cool. These compressors you showed has own oil sump and is seperate from the rest of fridgent. Basically same as other air compressors.

C-171 compressors circulates oil & freon. This is 3 double headed pistons in motion by swash plate.

This is the reason I asked about the oil circulation/separtor system.

Sorry, I thought the C171 was a York, or at least York-style. I'd be pretty pessimistic about being able to capture ALL the oil from the exhaust, and anything less will steadily run the compressor low on oil. It works in a/c compressors from refrigerators used as vacuum pumps because the actual mass flow rate of air is only appreciable during the first few seconds of pumping on a closed system, but here you will be moving lots of air all the time. Good luck.

Talking (bouncing off on yours gave me new thoughts and found trivas on this oiling system). A trivia: screw and vane compressors uses oil spray from sump that collects oil back from output.

This gave me idea:

Make up a oil trap/seperator and oil sump on pressure side, oil from sump is under pressure filtered then thru a regulator to few lb-sq pressure to the spray mist nozzle on intake side.

Vent the air pressure (unloader) when motor is off.

How about that?

Is there diagrams or pointers on oil seperator design?

Guys are using the York style compressors for vehicle mounted air compressors all over the place. The offroad jeep guys put air and welders onboard so they can repair breakage on the trail.
