Document Type and Number:
Japanese Patent JPS61142182
Kind Code:
U
Abstract:
A piston-type refrigeration compressor having a more secure valve plate seal is disclosed. A cylinder housing is provided with a cylinder block having a plurality of cylinders at one end. The end surface of the cylinder block near the cylinder is coupled to a cylinder head through gaskets and a valve plate. A circular depression is formed on the end surface of the cylinder block to accommodate the gasket substantially within the depression and thereby seal the cylinder block and valve plate. In this way, the outward expansion of the gasket is prevented which prevents the gasket from deteriorating.
