Abstract
A gasket having a surface thereof coated with an elastic membrane and adapted to be interposed, together with a valve plate and a discharge valve member, between a cylinder block and a housing of a refrigerant compressor under compression. The gasket includes an outer sealing portion for sealing an outer circumference of the compressor against an atmospheric environment therearound, and an inner sealing portion, connected to the outer sealing portion, for sealing between a high pressure region and a low pressure region within the compressor. Each of the outer and inner sealing portions includes in its entirety a deformable ridge which is shaped as a convexly curved projection with an apex line continuously extending along a length of the each outer and inner sealing portion. When the gasket is located in a proper position in the compressor, the apex lines of the ridges of the respective sealing portions are abutted to the front or rear housing of the compressor.
