COMPRESSOR CHECK VALVE

摘要

The present invention relates to a check valve for a compressor capable of reducing a flow noise of a refrigerant (P) using resonance in a specific frequency by the Helmholtz resonance effect. The check valve for a compressor (200) comprises: a valve cap (210) having a suction hole (213); a valve case (230) coupled to one side of the valve cap (210); a core (250) enabling a suction slit (231) and the suction hole (213) to selectively be communicated; a spring (S) installed in an inner space (233) of the valve case (230); and a resonance unit (270) coupled to the other side of the valve cap (210) and having a communication hole (273).
