PISTON TYPE COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To suppress the leak of a high-pressure coolant out of a compressor through the end surface of a cylinder block to suppress the deterioration of performance of the compressor resulted from the leak of coolant gas. SOLUTION: A cylindrical part 1a integrally provided on a rear housing 3 is located on the radial outside of a front fitting surface F constituted between the front end surface of a cylinder block 1 and the rear end surface of a front housing 2 and a rear fitting surface R constituted between the rear end surface of the cylinder block 1 and the front end surface of the rear housing 3, and the front fitting surface F and the rear fitting surface R are shielded by the cylindrical part 3a. The front end surface of the cylindrical part 3a is bonded to the rear end surface 20a of a motor housing 20 to form an internal sealed space. The sealing property in the front fitting surface F and the rear fitting surface R is improved, so that the leak of a high-pressure coolant out of the compressor through the front fitting surface F and the rear fitting surface R can be suppressed.
