Oscillating Rotor Compressor

Abstract

The invention discloses a swing rotor type compressor, and belongs to the technical field of compressors. The swing rotor type compressor is characterized in that an exhaust channel is formed in an eccentric wheel shaft, a high-pressure exhaust hole and a low-pressure exhaust hole are formed in a cylinder face of a swing rotor, and a high-pressure exhaust opening and a low-pressure exhaust opening are formed in a front end cap of an air cylinder. A cylinder face of an eccentric part of the wheel shaft is communicated with one end face through the exhaust channel in the eccentric wheel shaft. Within one rotating period of the eccentric wheel shaft, in the compression process, the exhaust channel in the eccentric wheel shaft, the exhaust holes in the swing rotor and the exhaust openings in the front end cap of the air cylinder are staggered; and in the high / low-pressure exhaust process, the exhaust channel in the eccentric wheel shaft, the low / high exhaust holes in the swing rotor and the low-high-pressure exhaust openings in the front end cap of the air cylinder are communicated. The swing rotor type compressor has the beneficial effects that the swing rotor type compressor achieves two-stage exhausting through changes of relative positions of the swing rotor, the eccentric wheel shaft and the front end cap of the air cylinder; compared with the manner that a two-stage compressor is adopted for achieving the same aim, the structure is simpler, and cost is lower.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a swing rotor compressor. Background technique [0002] Oscillating rotor compressors have the characteristics of being able to withstand large pressure differences and high mechanical efficiency, and are often used as compressors for heat pump systems. In a heat pump system that can provide two different heating temperatures at the same time, in order to meet different exhaust pressure requirements, a two-stage compressor is often used, and the structure is relatively complicated, and the cost will increase accordingly. Contents of the invention [0003] In order to solve the problem that the traditional single swing rotor compressor cannot provide two different exhaust pressures, the present invention provides a swing rotor type that relies on the mutual position changes of the swing rotor, eccentric wheel shaft and cylinder front end cover to realize two-stage exhaust. ...
