ABSTRACT:
A reciprocating piston type compressor for compressing refrigerant gas is provided with a main housing which includes a plurality of parallel cylinder bores arranged around the longitudinal axis of the cylinder block. The main housing has first and second cylinder blocks connected to each other by a plurality of bolts, the cylinder blocks including inner clamping faces and abutting faces. A plurality of pistons are slidably provided within the cylinder bores. An axially extending drive shaft is supported by the main housing for rotation through a pair of bearings. A swash plate is mounted on the drive shaft for rotation with the drive shaft. A pair of thrust bearings are provided between the swash plate and the inner clamping faces of the cylinder blocks to clamp and hold the swash plate therebetween. The clamping force on the thrust bearings from the inner clamping faces is controlled so that the clamping force does not exceed a predetermined allowable upper limit when the compressor is assembled.
