Vibration reduction compressor

Abstract

The invention provides a vibration reduction compressor comprising a cylinder body, an adjusting screw plug and a positioning gear. A cylinder hole is formed in the cylinder body, and a high-pressure vibration reduction cavity extending from the end face of the positioning gear to the interior of the positioning gear is formed in the end, close to the adjusting screw plug, of the positioning gear. A throttling device communicating with the cylinder hole and the high-pressure vibration reduction cavity and making gas in the cylinder hole enter the high-pressure vibration reduction cavity is arranged in the cylinder body. By forming the high-pressure vibration reduction cavity and arranging the throttling device, one gas suction and exhaust process is achieved every time a piston of the compressor runs by a circle. During exhaust, most of the high-pressure gas mixed with high-pressure refrigerant and oil in the cylinder hole is exhausted through an exhaust port, a small part of the gas enters the high-pressure vibration reduction cavity of the positioning gear through the throttling device, and therefore the pressure of the high-pressure vibration reduction cavity is gradually increased, the positioning gear can be pushed to be far away from the adjusting screw plug, and the buffering and vibration reduction effects are achieved. No mechanical noise can be generated, and therefore, the noise reduction effect is achieved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a vibration damping compressor. Background technique [0002] The rapid development of the automobile industry must also drive the development of the auto parts industry. A complete car is assembled by many parts. Among the many accessories of the car, the car air conditioner compressor is an important part. The automobile air-conditioning compressor is the heart of the automobile air-conditioning refrigeration system, which plays the role of compressing and transporting refrigerant vapor. [0003] like figure 1 As shown, the automobile air-conditioning compressor currently used in the market, the clutch is engaged during operation, and the attraction force is transmitted to the planetary plate a1 through the main shaft swash plate assembly, and then transmitted to the positioning gear a3 through the steel ball a2, and finally buffered by the spring a4 Balance, so that th...

Problems solved by technology

However, during this process, the spring a4 suddenly contacts the positioning gear a3 and the adjusting screw plug a7, which will generate mechanical noise instantly, and during the operation of the compressor, the pressure on the spring a4 has been fluctuating because the system pressure has been fluctuating. That is, mechanical noise continues to be generated; because the pressure on spring a4 has been fluctuating, spring a4 is prone to failure and thus affects the operation of the compressor
