Housing for a swash plate compressor

摘要

The piston type compressor of the present invention prevents high pressure refrigerant from leaking out of the compressor through the end face of the cylinder block and also prevents the degradation of the performance of the compressor due to the leakage of the refrigerant gas. The cylindrical wall (3a), which is placed radially outside the front coupling surface (F) formed by the front end face of the cylinder block (1) and the rear end face of the front housing (2), and the rear coupling surface (R) formed by the rear end face of the cylinder block (1) and the front end face of the rear housing (3), is formed integrally with the rear housing (3) and encloses the front coupling surface (F) and the rear coupling surface (R). The front end face of the cylindrical wall (3a) and the rear end face (20a) of the motor housing (20) are coupled together and a hermetic space is formed internally. The sealing ability at the front coupling surface (F) and the rear coupling surface (R) is improved and the high pressure refrigerant can be prevented from leaking out of the compressor through the front coupling surface (F) and the rear coupling surface (R). <IMAGE>
