Embodiment Construction

[0025] The following will refer to Figure 1 to Figure 9 A compressor according to a first preferred embodiment of the present invention will be described. refer to figure 1 , reference numeral 1 denotes a swash plate type compressor according to a first preferred embodiment of the present invention. The swash plate type compressor 1 (hereinafter referred to as "compressor") includes a front cylinder 3 and a rear cylinder 4, both of which are cylindrical. The front end surface of the rear cylinder 4 is coupled to the rear end surface of the front cylinder 3, thereby forming the cylinder assembly 2 of the swash plate type compressor. The cylinder assembly 2 is used as the cylinder block of the present invention. The front block 3 and the rear block 4 are formed of aluminum or an aluminum alloy. A front housing 5 is provided on the front end surface of the front cylinder 3 to cover the front end surface of the front cylinder 3 through the front port assembly 10 . A rear ho...

Abstract

A compressor includes a housing, a cylinder block, a valve plate, a discharge valve forming plate and a retainer gasket. The discharge valve forming plate includes a discharge valve, a connecting portion and a discharge valve engaging portion. The discharge valve opens and closes the discharge port. A plurality of discharge valve support portions extends from the connecting portion to support the discharge valve. The discharge valve engaging portion extends from the connecting portion. The retainer gasket includes a retainer, a gasket and a retainer gasket engaging portion. The retainer restricts an opening and closing operation of the discharge valve. The gasket ensures airtightness between the housing and the cylinder block. The retainer gasket engaging portion is formed by bending a part of the retainer gasket. The discharge valve forming plate and the retainer gasket are positioned by connecting the discharge valve engaging portion and the retainer gasket engaging portion.

Description

technical field [0001] The present invention relates to compressors, and more particularly to compressors comprising a retaining gasket and a discharge valve forming plate. Background technique [0002] Japanese Laid-Open Publication No. 11-230040 discloses a swash plate type compressor for a vehicle air conditioner. refer to Figure 14 , the swash plate compressor 71 includes a cylinder assembly 76 formed by coupling a gasket 88 to the rear end surface of the front cylinder block 76A and coupling the front end surface of the rear cylinder block 76B to the gasket 88 . A front housing 77 is provided on the front end surface of the front cylinder block 76A, and a rear housing 78 is provided on the rear end surface of the rear cylinder block 76B. A plurality of cylindrical cylinder bores 75 are formed in the cylinder assembly 76 . A piston 74 reciprocating therein is provided in the cylinder bore 75 . The piston 74 is connected to the swash plate 73 via a shoe 89 . The swas...
