Refrigerator compressor and cylinder cover assembly for refrigerator compressor

Abstract

The invention relates to a refrigerator compressor and a cylinder cover assembly for the refrigerator compressor, and belongs to the technical field of compressors. The cylinder cover assembly comprises a cylinder cover, wherein the cylinder cover is provided with an oil baffle plate and a cooling fin; an exhaust cavity is formed in the cylinder cover, and a limiting piece mounting base is arranged in the exhaust cavity; a mounting table is arranged on the upper surface of the limiting piece mounting base; the exhaust cavity is further provided with a limiting piece in contact with an exhaustvalve plate; a positioning table is arranged on the surface, facing the exhaust cavity, of the limiting piece; and the positioning table and the limiting table are connected with each other through anelastic piece. The cylinder cover is provided with an oil blocking structure, one part has multiple purposes, oil drops can be effectively prevented from being sucked by a silencer, the oil circulation rate of the system is reduced, and the problem that a box body is not refrigerated due to oil blockage is avoided. The oil blocking structure is arranged in the direction of an oil line throwing path, so that an oil line can be prevented from being thrown to an inlet of the air suction silencer.

Description

technical field [0001] The disclosure belongs to the technical field of compressors, and in particular relates to a cylinder head assembly for a refrigerator compressor and a refrigerator compressor. Background technique [0002] The statements herein merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The cylinder head is a key part of the refrigerator compressor, which can realize the separation of high and low pressure chambers during the operation of the compressor, and ensure the normal suction and exhaust cycle of the compressor. The cylinder head exhaust chamber plays the role of cushioning and noise reduction in the exhaust system. [0004] The inventor found that during the working process of the existing compressor motion system, in order to block the oil line and prevent the refrigerating machine oil thrown out by the crankshaft from being sucked into the muffler, it is usually realized by ...

AI Technical Summary

Problems solved by technology

[0004] The inventor found that during the working process of the existing compressor motion system, in order to block the oil line and prevent the refrigerating machine oil thrown out by the crankshaft from being sucked into the muffler, it is usually realized by changing the structure of the cylinder block, and different product platforms are not universal , the comprehensive cost is high, and the existing exhaust valve plate is installed in the groove of the valve plate, and is pressed and positioned by the exhaust valve reed and the exhaust valve limit plate. Depending on the plate structure, the optimal lift height cannot be selected for different product platforms and different displacements, which is not conducive to the optimization of compressor efficiency measurement, and the exhaust cavity of the cylinder head is equipped with reinforcing ribs and a limiting plate compression structure, which occupies The large volume of the exhaust chamber affects the exhaust efficiency
