Problems solved by technology

Therefore, when the discharge cover 41 is tightened, the degree of deviation of the discharge cover 41 is the diameter difference between the screw hole 41c and the fixing hole 1a, and the result that the cylinder 10 tightly inserted in the discharge cover 41 deviates from the discharge cover 41 simultaneously, so that the cylinder 10 and the discharge cover 41 deviate together. The concentricity deviation of the piston 20 exists, causing wear or friction noise

Embodiment Construction

[0032] The deviation preventing structure of the discharge cover for the reciprocating compressor of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0033] In the figure, the same parts as before are given the same symbols.

[0034] As shown in Figures 1 and 4, the compressor portion of the reciprocating compressor includes: a cylinder 10 that is inserted into a cylinder assembly hole fixed to the frame 1 through a through hole 11 that forms a compression space P inside; Inserted piston 20 that can move linearly in the through hole 11; combined with the end of the piston 20, open and close the suction valve 30 that penetrates the gas passage F formed in the piston 20; combined with the end of the cylinder 10 to cover the through hole 11 and discharge Valve assembly 40 .

[0035] The cylinder 10 includes a main body part 12 that is formed into a cylindrical shape and extended and tightly ...

Abstract

The present invention discloses one kind of deviation preventing structure for exhaust cover in reciprocating compressor. The deviation preventing structure includes cylinder with compressing space and inserted in fixing frame; piston combined with the runner of reciprocating motor to move linearly inside the compression space of the cylinder; and exhaust cover with exhaust valve limiting the exhaust of compressed fluid and to cover the compressing space of the cylinder. The exhaust cover is fixed to the frame with screws and at least one hole for the screw to pass through is slotted hole. The exhaust cover is so assembled that no deviation between the exhaust cover and the cylinder is produced and this can avoid the wear and friction noise of cylinder and piston during operation.

Description

technical field [0001] The present invention relates to a discharge cover of a reciprocating compressor, and more particularly to a displacement prevention structure for a discharge cover for a reciprocating compressor that prevents cylinder deviation caused by an assembly error when assembling the discharge cover. Background technique [0002] In general, a compressor is a machine that compresses a fluid such as air or refrigerant. A compressor generally includes a motor unit installed inside a closed container to generate a driving force, and a compressor unit that receives the driving force transmitted by the motor unit and sucks compressed gas. [0003] Such compressors are classified into scroll compressors, reciprocating compressors, scroll compressors, etc. according to the gas compression mechanism of the motor part and the compressor part. [0004] The reciprocating compressor transmits the driving force of the motor part to the piston, and the piston sucks, compre...
