Embodiment Construction

[0033] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0034] Such as figure 1 As shown, the present invention provides a piston assembly.

[0035] The piston assembly is arranged in the cylinder 10 , and the piston assembly includes a piston 20 , a driving rod mechanism 30 and a flexible connection mechanism 40 . Specifically, the driving rod mechanism 30 is drivingly connected with the piston 20, and the driving rod mechanism 30 drives the piston 20 to perform reciprocating motion. The flexible connection mechanism 40 is connected between the piston 20 and the drive rod mechanism 30 , and the drive rod mechanism 30 pushes and pulls the piston 20 through the flexible connection mechanism 40 . The radial rigidity of the flexible connection struc...

Abstract

The invention provides a piston assembly and a compressor with the same. The piston assembly is arranged in an air cylinder and comprises a piston, a drive rod mechanism and a flexible connection mechanism, wherein the drive rod mechanism is connected to the piston in a drive mode, and the flexible connection mechanism is connected between the piston and the drive rod mechanism for driving the drive rod mechanism to drive the piston to do reciprocating motion in the center direction of the air cylinder. The radial stiffness of the flexible connection mechanism is small, the piston can be concentric with the air cylinder when moving, the lateral force exerted on the piston from the air cylinder is lowered when the piston moves, frictional loss between the piston and the air cylinder is reduced, and the working performance is improved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a piston assembly and a compressor with the same. Background technique [0002] At present, the reciprocating compressors used in refrigerators and air conditioners on the market include the main components such as cylinders, pistons and motors. The gas is compressed into high-temperature and high-pressure gas, and finally completes the entire refrigeration system cycle through the condenser, capillary tube and evaporator. [0003] In order to reduce the friction between the piston and the cylinder, the compressor should try to ensure that the piston and the cylinder are concentric during the assembly process, so as to reduce the lateral force generated by the cylinder during the movement of the piston. But in fact, due to the design itself, as well as factors such as parts processing errors and assembly errors, it is impossible to ensure that the piston and the cylinder are comp...
