Abstract

The invention discloses a rotary compressor which includes the casing, the electromotion part and the compression part. The electromotion part locates on the top of the casing; the compression part which includes cylinder, rolling hoop, top axletree and lower axletree locates inside and on the bottom of the casing; there is compression cavity with some cubage in the cylinder; the sucking hole communicates with the compression cavity; the bypass opening locates the place which is some distance away the sucking hole; the discharge hole discharges the compressed gas from the compression cavity. The rolling hoop eccentrically connects with the rotation axis, rolls on the inner surface of the compression cavity and divides the space which is used for sucking and compression together with the inner surface. The spacing block is set between the sucking hole and the discharge hole, maintains spring contact with the rolling hoop and divides the compression cavity into sucking space and the discharge space. The makeandbreak unit selects and opens or closes the by-pass port according to compression module. The invention can get double compression energy by a compressor, provide adequate compression energy corresponding to the run condition realizes double compression energy and saves electric power.

Description

technical field [0001] The present invention relates to a compressor. In particular, it relates to a rotary compressor that can obtain two different compression capacities in a compression mode when rotating in one direction. Background technique [0002] Generally, a compressor is a machine that uses the power of a motor or a steam turbine to pressurize working fluids such as air and refrigerant to increase the pressure of the working fluid. This kind of compressor is widely used in the fields of home appliances such as air conditioners and refrigerators, as well as in production fields. [0003] According to the type of compression, compressors can be divided into volumetric compressors and turbo compressors. [0004] Among them, the volumetric compressor is widely used in the production field. The compression method of the volumetric compressor is to increase the pressure by reducing the volume. Volumetric compressors can be classified into reciprocating compressors a...
