ABSTRACT:
A drive shaft (17) is rotatably supported in a cylinder (12) by means of bearings (28), (29). A swash plate (24) fixed to the shaft (17) causes a piston (33) to reciprocate in a bore (18), (23) of the cylinder (12) upon rotation of the drive shaft (17) and swash plate (24). The piston (33), in combination with inlet (113) and outlet (58) valves communicating with the cylinder bore (18), (23) cause refrigerant fluid or the like to be compressively displaced through the bore (18), (23) and compressor (11). Passageways (123), (124) connect the cylinder bore (18), (23) to the bearings (28), (29) in such a manner that lubricant oil entrained in the refrigerant is forced by refrigerant pressure in the bore (18), (23) through the passageways (123), (124) to positively lubricate the bearings (28), (29 ) even during startup of the compressor (11).
