Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2022/158680
Kind Code:
A1
Abstract:
A scroll compressor is disclosed. A scroll compressor according to an embodiment of the present invention comprises: a compression part for discharging, to the inner space of a casing, a refrigerant compressed in a compression chamber; a discharge port for forming a flow path through which the refrigerant compressed in the compression chamber is discharged to the outside of the compression chamber; and a valve member, which has, at one end portion thereof, a root part fixed to a valve seat part of the compression part, forms a free end on the other end portion thereof, and has a head part to open/close the discharge port. A spacing part is provided between the head part of the valve member and the valve seat part to space the head part from the valve seat part in a state in which the compression part stops. Therefore, during operation of the valve member, the moving speed of the head part is reduced by means of the stiffness of the valve member so that impact force generated when the head part of the valve member collides with one surface of the compression part is reduced and impact noise generated thereby can be decreased.
