Abstract

The invention provides a pump body and a compressor comprising the same. The pump body comprises a crankshaft, an eccentric sleeve, a limiting part, a kinetic scroll plate and a static scroll plate, wherein the crankshaft comprises a drive shaft and an eccentric shaft eccentrically arranged on the drive shaft; an eccentric hole is formed in the eccentric sleeve, the eccentric hole is eccentricallyarranged relative to the external circumference of the eccentric sleeve, the eccentric sleeve can be arranged on the eccentric shaft asway in a sleeving manner through the eccentric hole, and a limiting groove is formed in the eccentric sleeve; the limiting part is connected with the crankshaft, is matched with the limiting groove, and is capable of limiting a radial movement range of the eccentric sleeve relative to the drive shaft; the kinetic scroll plate is connected with the eccentric sleeve; and the static scroll plate is matched with the kinetic scroll plate. According to the technicalsolution provided by the invention, the problems that the kinetic scroll plate and the static scroll plate of the compressor are abraded seriously due to contact under a severe working condition, andtooth breaking can be easily caused by liquid slugging in the prior art can be solved, so that reliability of the compressor is increased.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a pump body and a compressor having the same. Background technique [0002] With the development trend of new energy, electric vehicles and passenger car air conditioners are constantly emerging. The reliability requirements for electric vehicle and passenger car air conditioning systems are higher, and the reliability requirements for air conditioner compressors are higher, and the compressor's shock resistance and anti-turbulence adaptability The requirements are higher, so the compressor structure needs to be designed with corresponding anti-shock and anti-turbulence structure to improve the reliability of the compressor. [0003] When the air conditioning system operates in a low temperature environment, it is easy to form liquid refrigerant in the compressor. When the liquid refrigerant passes through the movable scroll and the fixed scroll, it is easy to cause the teeth...
