Abstract
A suction valve assembly of a reciprocating compressor includes: an inertial valve having a valve plate detachably attached at a valve seat of a piston, and opening and shutting the suction passage, and a support bar extended from a rear side of the valve plate, inserted into the suction passage and a plurality of guide grooves at regular intervals in a circumferential direction thereof; and guide pins slidably inserted into the guide grooves of the inertial valve and fixed at the piston to limit an opening rate of the valve plate, thereby minimizing a dead volume inside a compression chamber by making a valve side forming the compression chamber to be plane and strengthening a structural coupling strength of a valve.
Claims8
A suction valve assembly of a reciprocating compressor comprising:
- a piston disposed to be linearly movable at a cylinder forming a compression chamber and having a suction passage for sucking a fluid and a valve seat formed at a front side thereof;
- an inertial valve having a valve plate detachably attached at the valve seat of the piston, and opening and shutting the suction passage, and a support bar extended from a rear side of the valve plate, inserted into the suction passage and a plurality of guide grooves at regular intervals in a circumferential direction thereof;
- and
- guide pins slidably inserted into the guide grooves of the inertial valve and fixed at the piston to limit an opening rate of the valve plate.
