Therein among embodiment, described spring line comprises head arcuate segment, neck arcuate segment and tail straight segment three parts successively, described spring line integral body axisymmetricly, described neck arcuate segment caves inward with respect to head arcuate segment and tail straight segment, smooth transition between described head arcuate segment, neck arcuate segment and the tail straight segment.
Among embodiment, the distance between two the Line Segment of the tail straight segment of described spring line is 8 to 12 millimeters therein.
Therein among embodiment, the width between two curved lines of the neck arcuate segment of described spring line be between two Line Segment of described tail straight segment width 70% to 90%.
Among embodiment, described spring line is non-closed loop wire, and the two ends of the tail straight segment of described spring line end at the submarginal position of described valve block therein;
Described spring line is gap structure.
Among embodiment, described a plurality of screw mounting holes are symmetricly set on the marginal position of described suction valve chip therein, and its number is four.
Therein among embodiment, the center of the terminal point at the two ends of the tail straight segment of described spring line and two screw mounting holes wherein point-blank.
Among embodiment, described suction valve chip is the sheet rectangular configuration therein, and wherein three angles are fillet, and another angle is chamfering.
Among embodiment, described suction valve chip also comprises the vent that be arranged in parallel with the tongue center line therein.
Among embodiment, described exhaust hole is circular therein, and described vent is square.
The beneficial effects of the utility model: the exhaust port of the suction valve chip that above-mentioned Piston Refrigerant Compreessor is used is positioned at the tongue afterbody, and size is less, make the tongue of suction valve chip be easy to open, the suction valve chip integral rigidity increases simultaneously, can guarantee that suction valve chip closes in time, be difficult for occuring flutter, thereby the clearance volume that produces be less, guarantee the volume of pressurized gas, promote refrigerating capacity.
