Problems solved by technology

[0014] However, in the discharge device of the above-mentioned conventional reciprocating compressor, in the process of discharging the compressed refrigerant gas by repeatedly opening and closing the discharge valve, the compressed gas is discharged into the discharge cover, thus increasing the Pressure pulses in the exhaust cap
Therefore, the noise inside the exhaust cover increases, and when the exhaust valve 3 collides into the front end face of the cylinder by opening and closing the exhaust valve, the impact noise generated cannot be sufficiently reduced.
[0015] Moreover, in the case of installing a compressor with a discharge device, the return pipe connected to the discharge device receives pressure fluctuations, thus generating secondary noise when the refrigerator itself vibrates in response to the increased vibration level

Abstract

Discharge device for a reciprocating compressor, wherein the compressor comprises: a casing connected to a gas suction conduit for sucking gas; a cylinder located inside the casing; a compression unit including a piston reciprocating inside the cylinder; a reciprocating A type motor having an inner stator, an outer stator, and an armature reciprocating between them; and a frame unit supporting them by connecting the compression unit and the reciprocating motor, the unit including: a first cover part, in which Forming a valve body and at least one gas passage for controlling the discharge of compressed gas by opening and closing the contained cylinder; and a second cover part arranged continuously with the first cover part and connected to the gas discharge hole, so The gas compressed by the linear reciprocating motion in the cylinder can be discharged smoothly, thereby improving the reliability of the compressor.

Description

technical field [0001] The present invention relates to an exhaust device of a reciprocating compressor, in particular to a reciprocating compressor capable of reducing the noise generated by the compression pulse (compression pulse) of the refrigerant discharge gas and the noise generated by the operation of the entire compressor by designing the form of the cover part machine exhaust. Background technique [0002] Generally, the exhaust device of a reciprocating compressor is constructed so that the piston of the compressor and the armature of the reciprocating motor are integrally connected together, and the piston that reciprocates linearly in the cylinder sucks in gas, and then discharges it along the direction of movement of the piston. compressed gas. figure 1 is a cross-sectional view of the discharge device of the reciprocating compressor in the present invention. [0003] Such as figure 1 As shown, the exhaust device of the reciprocating compressor according to ...
