ABSTRACT:
A refrigerant compressor for effecting successive compression and exhaust strokes by the reciprocating action of a piston driven by an inclined oscillating plate. A rotor chamber communicates with an air inlet chamber through an air inlet silencer chamber while an exhaust chamber communicates with an outlet via an exhaust silencer chamber. The exhaust silencer chamber communicates with a lower sump chamber through a separator so that lubricating oil can be separated in the exhaust chamber and can flow to the sump chamber wherefrom the lubricating oil can flow back to the rotor chamber through a bore in a rotor drive shaft which communicates with the sump chamber through an orifice.
