The utility model discloses a following technical scheme realizes:
a rear cover of a compressor comprises a rear cover main body, wherein an inner cavity of the rear cover main body is axially provided with an annular plate, the annular plate divides the inner cavity of the rear cover main body into a high-pressure cavity and a low-pressure cavity, the high-pressure cavity is positioned on the outer side of the annular plate, and the low-pressure cavity is positioned on the inner side of the annular plate;
the rear cover body further comprises an air suction port and an air exhaust port, the air suction port is provided with a low-pressure one-way valve, the air suction port is communicated with the low-pressure cavity, and a high-pressure one-way valve is arranged at a channel where the air exhaust port is communicated with the high-pressure cavity.
Preferably, a plurality of support columns are circumferentially arranged in the low-pressure cavity.
Preferably, the rear cover main body further comprises a plurality of threaded holes arranged circumferentially.
An intelligent electric control compressor comprises a cylinder body, a front cover, a clutch assembly, a main shaft swash plate assembly and the compressor rear cover.
The utility model has the advantages that:
the utility model adopts the structure and design, the noise is lower when the compressor electric control valve is not started, so that the air inlet and outlet of the compressor have no air flow pulsation fluctuation, and the tiny air flow is sealed in the compressor to save energy;
and the utility model discloses novel structure, reasonable in design, convenient to use has stronger practicality.
