Problems solved by technology

[0005] That is to say, part of the balance conduit in the above-mentioned patent document is set on the cylinder body, and a part is set on the upper and lower flanges. Therefore, multiple parts need to be processed, the processing cost is high and the matching accuracy is also high, otherwise it is easy to cause leakage and affect compressor performance

Abstract

The invention relates to a compressor, in particular to a pump assembly of a rolling rotor compressor. The pump assembly of the rolling rotor compressor comprises an air cylinder, a roller and a slide sheet. A guiding channel enabling a gap, close to the suction port side, of the slide sheet to communicate with a spring hole is formed in the slide sheet or a hollow cavity. According to the pump assembly of the rolling rotor compressor, the pressure on the two sides of the slide sheet is balanced, the machining cost is low, the requirement for the assembling precision is low, and the technical problems that in the prior art, the pressure on the two sides of a slide sheet is not balanced, the machining cost is high, and the requirement for the assembling precision is high are solved.

Description

technical field [0001] The invention relates to a compressor, in particular to a pump body assembly of a rolling rotor compressor. Background technique [0002] The compressor usually includes a closed shell, a compression pump body, a motor assembly, a crankshaft, a gas-liquid separator, a suction pipe and an exhaust pipe. The stator and rotor form the motor assembly of the compressor, and the compression pump body includes a cylinder, an upper flange, a lower flange and a roller fixed on the eccentric part of the crankshaft. When working, the rotor rotates inside the stator, and drives the rollers to roll eccentrically in the cylinder through the crankshaft. The cylinder is divided into a high-pressure area and a low-pressure area through the sliding plate. Under the action of the eccentric rolling of the rollers, the low-pressure refrigerant passes through the The suction pipe in the high-pressure zone is sucked into the cylinder for compression until it is compressed to...
