Embodiment Construction

[0019] refer to Figure 1 to Figure 4 , the embodiment of the present invention will be described as follows.

[0020] figure 2 is a sectional view of a compressor according to an embodiment of the present invention. As shown in the figure, a compressor 1 is equipped with a pair of cylinders, that is, a front cylinder 2 and a rear cylinder 3, which are axially butted on their end faces to form a cylinder assembly, and a sealing ring 4 is provided at the joint. The front cylinder body 2 and the rear cylinder body 3 are made of aluminum or aluminum alloys.

[0021] The front cylinder body 2 and the rear cylinder body 3 each have a through hole 5 at their centers. A drive shaft 6 is inserted into the through hole 5; the drive shaft 6 is rotatably supported by a radial bearing 7, the bearing 7 is installed in the through hole 5 of the front cylinder block 2, and another radial bearing 8 is installed in the rear cylinder Inside the through hole 5 of the body 3. A swash plate ...

Abstract

The present compressor prevents the deformation of the baffle plate and does not damage the sealing performance of the metal gasket provided between the casing member for closing the compression chamber of the cylinder block assembly and the discharge valve forming plate. The discharge valve forming plate is disposed between a valve plate and the cylinder assembly, wherein the valve plate has at least one outlet through which fluid compressed in the compression chamber of the cylinder assembly is injected into a discharge chamber of the housing. The baffle plate used to limit the opening range of the injection valve is integrally formed on a metal gasket, and the gasket is arranged between the forming plate of the discharge valve and the casing. The casing is provided with a restricting portion at a position corresponding to the base of the raised portion of the baffle for restricting an adjacent portion of the top surface of the raised portion.

Description

technical field [0001] The present invention relates to a compressor for use in, for example, a vehicle air conditioning system. Background technique [0002] Swash plate compressors for vehicle air conditioning systems are known. For example, Japanese Patent Application No. 59-113278 published on June 29, 1984 in the name of Nippon Denso Ltd. and European Application published on October 28, 1994 in the name of Sanden Corporation This swash plate compressor disclosed in the object 0595313A1 has a cylindrical compression chamber in the cylinder assembly. The fluid to be compressed is compressed by pistons, which are used as fluid compressing elements and are arranged in each compression chamber. [0003] The swash plate compressor is also equipped with a front cover and a rear cover as casing members for protecting the compression chamber of the cylinder assembly. The valve plates are respectively arranged between the front cover and the cylinder assembly and between the ...
