Problems solved by technology

[0004] However, the problem with this constraint structure is that when there is a pressure difference between the two ends of the pin, the gas on the high-pressure side leaks to the low-pressure side through the gap between the pin and the pin hole
Therefore, when there is a pressure difference between the two ends of the pin, the cooling capacity of the compressor will be affected due to the existence of leakage

Abstract

The invention provides a compressor. The compressor comprises a cylinder, a flange located at the lower part of the cylinder and a cover plate located at the bottom of the flange. A pin hole is arranged in the flange, a pin is arranged in the pin hole, a part of the cover plate located at the pin is provided with a first vent hole communicated with the pin hole and the other end of the first went hole is communicated with an air suction port of the cylinder through a second went hole on the flange. The compressor can prevent leakage-caused influence on a compressor refrigerating capacity when difference of pressures at two ends of the pin exists. The invention also relates to a method for reducing a leakage amount of the compressor.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a compressor and a method for reducing the leakage of the compressor. Background technique [0002] In a rolling-rotor refrigeration compressor with a multi-cylinder structure, one or more cylinders have two operating modes: idling (the crank rotates but does not participate in compression) and load, to adjust the cooling capacity of the compressor. [0003] For example, in the patent Nos. CN103244412A and CN100564881C, in the structure with the constraint mode of the slide vane as the pin constraint, by controlling the external air circuit, changing the pressure on one side of the pin to control the motion state of the pin, so as to realize the control of the slide vane. Constrain and unconstrain. [0004] However, the problem with this constraint structure is that when there is a pressure difference between the two ends of the pin, the gas on the high pressure side leaks to the low ...
