Embodiment Construction
[0038] see in conjunction Figures 1 to 10 As shown, according to the embodiment of the present invention, the pump body assembly includes a suction port, an air supply port 1, a roller 2 and a cylinder 3, the cylinder 3 has a working chamber, and a valve hole 4 is also arranged in the pump body assembly, and the valve hole 4 One end communicates with the working chamber. There is an air supply channel 5 between the air supply port 1 and the valve hole 4. A valve core 6 is slid inside the valve hole 4. The valve core 6 is used when the roller 2 separates the air supply port 1 from the suction port. The gas supply port 1 communicates with the compression cavity of the working cavity, and / or closes the gas supply channel 5 when the pressure of the compression cavity of the working cavity is greater than the gas supply pressure.
[0039] During the air supply process of the compressor, the air supply channel 5 can be opened or closed by the movement of the valve core 6 in the val...
