Embodiment Construction

[0038] see in conjunction Figure 1 to Figure 17 As shown, according to the embodiment of the present invention, the pump body assembly includes a cylinder 1, a roller 2 and a slide 3, the roller 2 is rotatably arranged in the cylinder 1, and the cylinder 1 is provided with a slide groove 4 and an exhaust groove 5 and the suction port 6, the sliding piece 3 is slidably set in the sliding piece groove 4, one end of the sliding piece 3 abuts against the outer circumference of the roller 2, and the side of the sliding piece 3 facing the exhaust groove 5 is provided with a first muffler chamber 7. During one rotation cycle of the roller 2, the first muffler chamber 7 is not connected to the suction port 6.

[0039] When the pump body assembly is working, since the first muffler chamber 7 and the suction port 6 are not connected during the entire rotation cycle of the roller 2, high-pressure gas will be squeezed in from the compression chamber during the exhaust process of the comp...

Abstract

The invention provides a pump body module and a compressor. The pump body module comprises a cylinder (1), a roller (2) and a slide piece (3); the roller (2) is rotationally arranged in the cylinder (1); the cylinder (1) is provided with a slide piece groove (4), an exhaust groove (5) and an air sucking port (6); the slide piece (3) is slidingly arranged in the slide piece groove (4); one end of the slide piece (3) butts against the periphery of the roller (2); a first silencing cavity (7) is formed in the side, towards the exhaust groove (5), of the slide piece (3); and in one rotating periodof the roller (2), the first silencing cavity (7) dose not communicate with the air sucking port (6). The pump body module can effectively prevent the silencing cavity from influencing the air sucking quantity of the compressor, and guarantees the working energy efficiency of the compressor.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a pump body assembly and a compressor. Background technique [0002] Such as figure 1 As shown, it is an existing compressor muffler chamber structure, which includes two parts, the introduction passage 1' and the cavity 2'. The silencer chamber is arranged at the exhaust hole 4' of the cylinder 3'. When the compressor is running, the high-pressure refrigerant in the silencer chamber cannot be discharged from the cylinder 3'. Such as figure 2 As shown, when the roller 5' rotates through the muffler cavity, the high-pressure refrigerant in the cavity is released into the cylinder 3'. At this time, the cylinder 3' is still in the suction state, which will affect the suction capacity of the compressor, resulting in The clearance volume of the compressor increases. In addition, this part of the gas that has been compressed to high pressure is released to the sucti...
