Abstract

A high-performance hermetic type compressor in which the influence of a cylinder bore deformation caused during assembly is reduced and the sealing tightness between a piston and a cylinder block is improved. A bore hole in the cylinder block has a hollow portion. Depth H1 of the hollow portion is larger than thickness H2 of compression space V at the moment when the pressure in the compression space V reaches the discharge pressure level Pd.
