Problems solved by technology

However, this design structure easily leads to two main problems. The first is that the cost of the increased rotary compression chamber is too high, and the cost of a series of corresponding structures remains high; the second is that the efficiency of the increased rotary compression chamber is low

Abstract

The invention discloses a cylinder, a compression mechanism, a rotary compressor and a heat pump device. A compression cavity for rolling fit of a roller is defined in the cylinder, a sliding sheet groove and a first air suction port, both facing an opening of the compression cavity are formed in the circumferential wall of the cylinder, a piston cavity is defined in the circumferential wall of the cylinder, and the piston cavity is provided with a communication port formed in the inner circumferential surface of the compression cavity. According to the cylinder, the air discharge amount increasing mode of the cylinder can reduce the number of parts of the compressor, reduce the size and the weight, and greatly reduce the cost.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a cylinder, a compression mechanism, a rotary compressor and a heat pump device. Background technique [0002] At present, there are technologies such as two-stage compression, multi-stage compression, independent compression, and variable volume compression in the air-conditioning industry. Design and match to achieve the above technical goals. However, this design structure easily leads to two main problems. The first is that the cost of the increased rotary compression chamber is too high, and the cost of a series of corresponding structures remains high; the second is that the efficiency of the increased rotary compression chamber is low . Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a cylinder of a rotary compressor, which can add a pisto...
