Abstract

The invention relates to a by-pass valve assembly of a positive-displacement rotary compressor. The main structure of the invention comprises a valve board moving with pressure difference to open and close a by-pass hole, a valve board guide mounted on the joint face between the by-pass hole and the assembling space holding the valve board inside it and guiding the valve board to move to thickness direction, a fixing member communicated on an inner peripheral surface at the front of the valve guide making the valve board and the valve guide modularized together.

Description

Technical field [0001] The present invention relates to a bypass valve of a compressor, and more specifically, to a bypass valve assembly of a rotary compressor with a variable capacity. Background technique [0002] Generally speaking, a compressor is a device that compresses fluids such as refrigerant gas. According to the fluid compression method, compressors can be divided into rotary compressors, reciprocating compressors and scroll compressors. [0003] The rotary compressor has an electric mechanism part and a compression mechanism part inside a casing, and the electric mechanism part and the compression mechanism part are respectively combined on both ends of a rotating shaft, and the rotational force of the electric mechanism part is transmitted to the compression mechanism part. , Thereby compressing the refrigerant in the compression mechanism. [0004] Such a rotary compressor is suitable for most air conditioning devices such as air conditioners. Moreover, recent tre...
