Vortex type compressor

Abstract

The invention relates to a radial sealing device of a vortex type compressor. The vortex type compressor comprises a rotating shaft with a drive pin which is eccentric relative to a rotating center ofthe shaft; a mobile scroll combined with the drive pin of the rotating shaft, which is used for compressing a refrigerant when matched with an immobile scroll to perform the rotating motion; a sliding shaft sleeve capable of sliding in the radial direction between the drive pin of the rotating shaft and the mobile scroll and transferring the rotating force of the rotating shaft to the mobile scroll; also comprises more than one elastic component axially arranged between the drive pin of the rotating shaft and the sliding shaft sleeve, which provides the elastic force to the sliding shaft sleeve in the sliding direction. Therefore, the problem that the sliding shaft sleeve is not necessary to be pushed following with the pressure variation of a compression chamber, thereby reducing the radial leakage of the compressor; and the collision between the sliding shaft sleeve and the drive pin can be buffered, thereby reducing the noise.

Description

technical field [0001] The invention belongs to the field of scroll compressors, in particular to a scroll compressor which can effectively prevent refrigerant from leaking through the side surfaces of scroll plates. Background technique [0002] In general, scroll compressors are not easy to minimize the leakage gap due to their complex scroll plate shape, and the leakage in scroll compressors is formed through the gap between the fixed scroll and the movable scroll of. According to the leakage path of the refrigerant, the above gap can be divided into an axial gap and a radial gap. In particular, the radial clearance refers to the clearance between the side surfaces of the scroll plates of the fixed scroll and the movable scroll. Therefore, in order to reduce the gap between the side surfaces of the scroll plate and expand and contract the movable scroll according to the pressure change of the compression chamber, it is necessary to prevent the pressure of the compressio...

Problems solved by technology

[0007] In order to solve the technical problems existing in the prior art, the present invention provides a device that has nothing to do with the running state, and can make the movable scroll close to the fixed scroll, thereby improving the sealing performance and the compression performance; in addition, even if the compression chamber The rapid rise of the pressure can also make the movable scroll retreat very softly, thereby reducing the impact force between the fixed scroll and the movable scroll, thereby reducing the damage or noise of the plate; and processing at a predetermined angle The angle of the driving pin of the rotation auxiliary can be shared regardless of the capacity of the compressor, so the scroll compressor can reduce the processing cost
