Abstract
The present invention relates to a valve system for the hermetic reciprocating compressor, and more particularly, to reduce the gap volume of the spouting hole so as to help smoothly spout out the refrigerant through the spouting hole formed at the valve plate, to increase the amount of the refrigerant to be sucked into the cylinder, to increase the density of the sucked refrigerant, and finally to improve the efficiency of the hermetic reciprocating compressor. This invention comprises refrigerant leakage preventive part formed on the upper side of the valve plate to prevent the leakage of the refrigerant being sucked into the cylinder placed in front of the suction valve; the spouting part to open and close the spouting hole formed within the refrigerant leakage preventive part; the elastic part on the spouting part to open and close the spouting hole by the gap of small pressure while maintaining the small interval with the spouting part; the movement height limiting part to restrict the movement height of the spouting part by inserting and connecting the limiting part with the refrigerant leakage preventive part; and the spouting valve breakaway preventive part to prevent the b…
