Abstract
A compressor for a refrigerant gas wherein a rotor acts on a rocking plate to effect rocking thereof and reciprocation of pistons in cylinder bores to produce suction and exhaust strokes for refrigerant gas. A lubricant is contained in a sump in the compressor casing and it is atomized and mixed with refrigerant gas which leaks past the pistons. A duct is formed in the casing for conveying the mixture of refrigerant gas and lubricant from the casing under the action of the suction stroke of the pistons. The mixture is delivered at the inlet for refrigerant gas and the total mixture now flows to a separator where the lubricant is separated from the refrigerant gas. The refrigerant gas is then supplied into the cylinder bores during the suction stroke and the lubricant is delivered into a reservoir where it is forceably delivered back into the casing to the sump.
