Embodiment Construction

[0038] see in combination 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 provided in the pump body assembly. One end is communicated with the working chamber, there is an air supply channel 5 between the air supply port 1 and the valve hole 4, and a valve core 6 is slidably arranged in the valve hole 4. The valve core 6 is used when the roller 2 separates the air supply port 1 and the suction port The air supply port 1 is communicated with the compression chamber of the working chamber, and / or the air supply passage 5 is closed when the pressure of the compression chamber of the working chamber is greater than the air 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 ...

Abstract

The invention provides a pump body assembly and a compressor. The pump body assembly comprises an air sucking opening, an air supplementing opening (1), a roller (2) and an air cylinder (3), the air cylinder (3) is provided with a working cavity, a valve hole (4) is further formed in the pump body assembly, one end of the valve hole (4) is communicated with the working cavity, an air supplementingchannel (5) is arranged between the air supplementing opening (1) and the valve hole (4), a valve element (6) is arranged in the valve hole (4) in a sliding manner, the valve element (6) enables theair supplementing opening (1) to be communicated with a compression cavity of the working cavity when the air supplementing opening (1) and the air sucking opening are isolated through the roller (2),and / or the air supplementing channel (5) is closed through the valve element (6) when the pressure of the compression cavity of the working cavity is larger than the air supplementing pressure. According to the pump body assembly, compressor supplementing air backflow can be avoided, sufficient compressor supplementing air is guaranteed, and the compressor working energy efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of air compression, and in particular relates to a pump body assembly and a compressor. Background technique [0002] At present, there are two types of air supply technologies for single-cylinder compressors. One is to open the air supply port on the cylinder near the compressor exhaust port, and the other is to open the air supply port on the upper or lower flange. [0003] The main drawback of these two structures is that the injection refrigerant cannot be prevented from flowing back to the suction pipe, or the area of ​​the injection port is limited, which leads to unsatisfactory performance of the compressor. If the air supply port is opened on the cylinder, when the roller rotates through the air supply port, the air supply port and the suction hole are connected, so that the supply air flows back to the suction hole, which reduces the energy efficiency of the compressor. When the air supply port is ...
