Abstract
A hermetic type compressor that includes a cylinder having a compression chamber with a cylinder head coupled to the cylinder to seal the compression chamber. A fastener fastened to the cylinder couples the cylinder head to the cylinder. A fastening hole is formed in the cylinder into which the fastener is received. A bush may be disposed between the fastener and fastener hole. The fastener may be made of a material having a thermal expansion coefficient less than that of the cylinder. Additionally, the bush may be made of a material having a thermal expansion coefficient greater than that of the cylinder.
