Abstract

PURPOSE: To obtain a check valve which can be manufactured easily with very low cost, by limitting the length of stroke of the valve and preventing falling down of it, and providing a throttle portion to flow the fluid from the valve seat annular material to the valve body made of a pipe.
CONSTITUTION: With refrigerant flowed from side A to side B, a valve 13 is touched to the center recess 15 of the throttle portion 14 by the refrigerant pressure, the refrigerant flows through the gap 16, 17, 18, 19 between the throttle portion 14 and the valve 13 respectively, and flows to side B. In this case, since the valve 13 is touched to the center recess 15 of the throttle portion 14 by refrigerant pressure, noise does not issue due to touching to the wall surface 20 of the valve body 12 made of pipe. On the other hand, if the refrigerant tries to flow from side B to side A, as the valve 13 is sealed to the valve seat annular material 2 by its refrigerant pressure, the refrigerant does not flow.
