Abstract

The invention discloses an exhaust device of a rolling rotor compressor pump body, mainly comprising an air cylinder provided with a round pore passage, a bent valve plate, a lift limiter with steps, an air cylinder end cover with a stepped exhaust hole, and a gasket, wherein the valve plate, the gasket and the lift limiter are installed in the pore passage of the air cylinder; after the compressor is assembled, the upper end cover of the air cylinder, the lower end cover of the air cylinder and the shell of the compressor seal the pore channel on the air cylinder to form an exhaust space which takes an opened valve plate as an inlet and the stepped exhaust hole on the air cylinder end cover as an outlet. The exhaust device has the advantages of small exhaust loss, low exhaust noise and being easy in processing and assembly.

Description

technical field [0001] The invention belongs to the technical field of rotary refrigeration compressors, and in particular relates to an exhaust device for a pump body of a rolling rotor compressor. Background technique [0002] The widespread use of refrigeration and air conditioning makes it one of the main equipment for energy consumption. High efficiency and low noise are the main goals of the development of refrigeration compressor technology. The existing research results show that the exhaust device of the pump body has a direct impact on the efficiency and noise of the compressor. The pump body of the rolling rotor compressor is composed of a cylinder, a crankshaft, a roller sleeve, an upper end cover of the cylinder, a lower end cover of the cylinder, a sliding vane and a sliding vane spring. In order to discharge the compressed gas out of the pump cavity, the exhaust device is generally assembled from the exhaust hole on the pump body, the valve plate and the lift...
