ABSTRACT:
A slant plate compressor with a variable displacement mechanism including a driving mechanism having a drive shaft is disclosed. The compressor includes a compressor housing having a cylinder block. A plurality of peripherally located cylinders are formed through the cylinder block. A piston is slidably fitted in each of the cylinders and is reciprocated by the driving mechanism. An inner end of the drive shaft is rotatably supported in the cylinder block by bearing which is fixedly disposed within a central bore formed through the cylinder block. Both rearward and radial forces acting on the drive shaft are effectively received and compensated for by the bearing without providing an axial position adjusting element, such as, a washer having the various thicknesses for adjusting an axial position of the drive shaft.
