Problems solved by technology

During this process, the valve noise is caused by the collision between the suction valve (43) and the front face of the piston (42). When the impact is severe, the valve will be damaged by the impact

Embodiment Construction

[0030] The valve shock buffer device of the reciprocating compressor of the present invention will be described in detail below with reference to the preferred embodiment shown in the figure.

[0031] Such as image 3 , 4 , 5, the valve shock buffer device of the reciprocating compressor of the present invention includes: inserted and fixed on the frame mechanism (refer to figure 1 ) (20), and a cylinder (41) forming a compression space (P) inside; a piston (110) slidably inserted into the compression space (P) of the cylinder (41), and a gas is formed inside the piston (110) Flow path, piston (110) and reciprocating motor (refer to figure 1 ) (30) The mover of (30) performs linear reciprocating motion together, and changes the volume of the compression space (P); it is arranged on the front end of the piston (110) to open and close the suction valve (120) of the suction through hole (112); An elastic component (130) inserted around the suction through hole (112) of the piston (...

Abstract

A valve impingement cushioning device of the reciprocating compressor comprises cylinder forming the compressing space, piston which can slide into the compressing space of piston and gas flow path in the piston. The piston and mover make straight reciprocating motion together, inbreathe the air into the compressing space through gas flow path, discharge it after being compressed, connect with the suction valve on the front end of piston which adjusts the suction of gas dismountablly and has the bleeder valve on the front end of cylinder. Its features lie in: there is flexible assembly absorbing the impact force of the suction valve at the front end of piston facing with the the suction valve and buffer unit at the end of the flexible assembly to buffer and absorb the impingement between the suction valve and the front end of piston. Thus, it can reduce the valve noise caused by the suction valve and the front end of piston when closing the suction valve, prevent the dilapidation caused by the impingement of suction valve and increase the reliability of reciprocating compressor.

Description

Technical field [0001] The invention relates to a reciprocating compressor, in particular to a valve buffer device of the reciprocating compressor. Background technique [0002] Generally, the reciprocating compressor sucks, compresses, and discharges refrigerant gas while the piston reciprocates linearly inside the cylinder. [0003] Such as figure 1 As shown, the conventional reciprocating compressor is composed of a casing (casing, 10), a frame mechanism (20), a reciprocating motor (30), a compression mechanism (40), and a resonance spring mechanism (50). The housing (10) is in communication with the gas suction pipe (SP) and the gas discharge pipe (DP); the frame mechanism (20) is elastically supported and arranged inside the housing (10); the reciprocating motor (30) is fixed Inside the housing (10) and supported by the frame mechanism (20); the compression mechanism (40) is connected to the reciprocating motor (30) and is supported by the frame mechanism (20); the resonanc...
