CLOSED TYPE COMPRESSOR

摘要

PURPOSE: To provide a high performance closed type compressor capable of improving sealability between a piston and a cylinder block by reducing the effect of deformation of a cylinder bore in assembly. CONSTITUTION: A hollow part 10a is provided in a bolt hole 10 of a cylinder block 2, and its depth H1 is made larger than the thickness H2 of a compression chamber V when a pressure in the compression chamber V is equal to a delivery pressure Pd.
