The specific implementation mode is as follows:
the present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 to 5, the utility model discloses a single cylinder vane type vehicle air conditioner compressor, including cylinder 1, the quantity of cylinder 1 is one, and 1 hole of cylinder is circular, and the front end of cylinder 1 is equipped with front baffle 4, and the rear end of cylinder 1 is equipped with backplate 5.
A rotor 2 is arranged in the cylinder 1, and the rotor 2 is eccentrically arranged relative to the cylinder 1. The front end of the rotor 2 penetrates through the front baffle 4 and is connected with an air-conditioning engine, and the rear end of the rotor 2 is arranged on the rear baffle 5 through a bearing. The end face of the front baffle 4, the surface of the inner hole of the cylinder 1, the end face of the rear baffle 5 and the outer surface of the rotor 2 form a working cavity of the rotary vane compressor, and the exhaust port 9 is located at the position, closest to the rotor 2, of the cylinder 1.
Three blades 3 are evenly distributed on the rotor 2, the blades 3 are installed in a sliding groove 6 on the circumferential surface of the rotor 2, the sliding groove 6 penetrates through the rotor 2 along the axial direction, and the length of each blade 3 is consistent with the length of an inner hole of the cylinder 1. 4 terminal surfaces of preceding baffle, the rear portion of rotor spout 6, blade 3 one side and 5 terminal surfaces of backplate have constituted three back pressure chamber 14, it has back pressure hole 10 and back pressure groove 11 to open on the backplate 5, back pressure groove 11 and back pressure chamber 14 intercommunication, inject highly compressed oil-gas mixture into back pressure groove 11 through back pressure hole 10, oil-gas mixture gets into back pressure chamber 14 through back pressure groove 11, make blade 3 opposite side and 1 inner wall of cylinder keep laminating through oil-gas mixture, blade 3 through the last rotatory of rotor 2 separates into three compression chamber 7 with the working chamber.
