Benefits of technology

The present invention relates to a compressor for a vehicle air conditioning system. The compressor includes a housing, a cylinder block, a valve plate, a discharge valve forming plate, and a retainer gasket. The discharge valve forming plate is positioned to open and close a discharge port and is supported by a plurality of discharge valve support portions. The retainer gasket is positioned to ensure airtightness between the housing and the cylinder block. The discharge valve forming plate and the retainer gasket are connected together to improve the compressor's performance and stability.

Problems solved by technology

However, a sophisticated technology is required to perform the polishing while leaving convex portions in the valve plate 81, leading to an increase in manufacturing costs.

Embodiment Construction

[0025]The following will describe a compressor according to a first preferred embodiment of the present invention with referring to FIGS. 1 through 9. Referring to FIG. 1, reference numeral 1 designates a swash plate type compressor according to the first preferred embodiment of the present invention. The swash plate type compressor 1 (hereinafter referred to as “compressor”) includes a front cylinder block 3 and a rear cylinder block 4 which have a column shape. The front end surface of the rear cylinder block 4 is joined to the rear end surface of the front cylinder block 3 thereby to form a cylinder assembly 2 of the swash plate type compressor. The cylinder assembly 2 serves as a cylinder block of the present invention. The front cylinder block 3 and the rear cylinder block 4 are formed of aluminum or aluminum alloy. A front housing 5 is provided on the front end surface of the front cylinder block 3 through a front valve port assembly 10 for covering the front end surface of th...

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

BACKGROUND OF THE INVENTION[0001]The present invention relates to a compressor and, more particularly, to a compressor including a retainer gasket and a discharge valve forming plate.[0002]Japanese Patent Application Publication No. 11-230040 discloses a swash plate type compressor used for a vehicle air conditioner. Referring to FIG. 14, a swash plate type compressor 71 includes a cylinder assembly 76 formed by joining a gasket 88 to the rear end surface of the front cylinder block 76A and joining the front end surface of a 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 columnar cylinder bores 75 are formed in the cylinder assembly 76. A piston 74 which reciprocates in the cylinder bore 75 is provided in the cylinder bore 75. The piston 74 is connected to a swash plate 73 through a shoe 89. The sw...
