Abstract

The invention provides a compressor. The compressor comprises an air cylinder, a roller, a crankshaft and a springback structure, wherein the air cylinder is provided with a first movable cavity; the roller is movably arranged in the first movable cavity and provided with a second movable cavity; the crankshaft is movably arranged in the second movable cavity; and the springback structure is arranged in the second movable cavity and located between the roller and the crankshaft or in the crankshaft, so that at least part of the crankshaft rebounds in the second movable cavity through the springback structure. Through the technical scheme provided by the invention, the technical problem that a compressor in the prior art is prone to being damaged can be solved.

Description

technical field [0001] The present invention relates to the technical field of compressors, in particular to a compressor. Background technique [0002] At present, the rotary compressor in the prior art reduces the volume of the compression cavity in the pump body through rotational movement, so as to realize the function of the compressor to compress the refrigerant. In order to reduce the leakage during the compression process, the matching clearance of the pump body is made relatively small (generally around 20um) to have a better effect. In some special equipment, a large amount of refrigerant needs to be injected, resulting in a large amount of liquid return from the compressor. [0003] However, during the compression cycle of the compressor, the liquid is not easy to discharge, because the liquid refrigerant is basically incompressible, and finally only the deformation of the crankshaft avoids the liquid, which is easy to cause damage to the pump body. For example:...
