摘要： 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.

A discharge valve forming plate is provided between a valve plate having at least one discharge port through which a fluid compressed in a compression chamber of a cylinder block assembly is discharged into a discharge chamber of a housing and the cylinder block assembly. A retainer for restricting the magnitude of opening of a discharge valve is integrally formed in a metal gasket which is provided between the discharge valve forming plate and the housing. The housing is provided with a restricting section at a position corresponding to a proximal portion of a rising portion of the retainer for restricting the proximal portion of the top surface of a rising portion.

摘要： A valve structure includes a central valve plate having a valve hole, and a flexible valve element having a root portion lying on the central valve plate and a bendable portion to open and close the valve hole. A retainer element has a retaining surface to restrict deformation of the valve element when it is bent toward the retainer element to open the valve hole. The profile is expressed in a two-dimensional coordinate system (x, y), and the freely bent shape is represented by coordinates (x, f(x)) obtained by pushing the valve element at an abscissa position corresponding to the center of the valve element. The retaining surface has a profile containing a coordinate (x′, f(x′)−K) so that the profile is displaced toward the central valve plate with respect to a freely bent shape of the valve element.

摘要： A compressor includes a cylinder block and a housing connected to the ends of the cylinder block. A suction chamber and a discharge chamber are defined in the housing, respectively, and the chambers are divided by a bulkhead, or wall. A valve plate, which has a discharge port for connecting the cylinder bores with the discharge chamber, is positioned between the cylinder block and the housing. A discharge valve is provided for selectively opening and closing the discharge port. A gasket is positioned between the housing and the valve plate, and the gasket is held to the bulkhead. The gasket has a bulkhead seal portion, which is between the bulkhead and the valve plate for sealing between the discharge chamber and the suction chamber, and a protruding portion, which protrudes radially beyond the bulkhead, extending along and contacting the valve plate.
