Valve assembly for variable swash plate compressor

Abstract

Disclosed herein is a valve assembly for a variable swash plate compressor. Since an opening hole of a suction reed of the valve assembly for the variable swash plate compressor is enlarged toward a suction port of a valve plate and refrigerant is also introduced into a cylinder bore through the opening hole when the suction port is opened, performance of a compressor may be enhanced by an increase in flow rate.

Description

technical field [0001] The present invention relates to a valve assembly of a variable swash plate compressor, and in more detail, relates to a variable swash plate compressor capable of improving the performance of the compressor by increasing the flow rate and improving durability, thereby prolonging the life of the compressor valve components. Background technique [0002] Compressors that perform the role of compressing refrigerant in vehicle refrigeration systems have been developed in various forms, and are basically classified into reciprocating compressors that perform compression by reciprocating motion and compression by rotary motion according to the driving method. rotary compressor. [0003] As a kind of reciprocating compressor, there is a swash plate compressor, and the swash plate compressor includes a fixed capacity type in which the setting angle of the swash plate is fixed and a variable capacity type in which the discharge capacity can be changed by chan...

Problems solved by technology

[0028] In addition, since the both side leg portions 64b of the suction reed 64 are arranged parallel to each other, the structure is weak against the torsional load applied to the suction reed 64 during the opening and closing operation.

[0029] Therefore, when deterioration occurs due to repeated opening and closing, the base end portion 64c is likely to be broken.

If the base end portion 64c breaks, the suction reed 64 cannot operate normally, therefore, the suction of the refrigerant through the suction port 62 of the valve plate 60 cannot be normally realized, thus, the process of compressing and discharging the refrigerant cannot be normally realized. Therefore, there is a problem that the compressor 10 eventually becomes inoperable.
