Title: Check valve for feeding fluid under high pressure
Inventor: KAMINARI TSUTOMU
IPC: B01F25/46
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To prolong the service life of a check valve used for feeding fluids under high pressure and to maintain stable high pressure feeding by making one or both of a fixed side valve member and a moving side valve member in the check valve of elastic high molecular materials. SOLUTION: A check valve using a ball-like moving side valve member 9 is constructed in such a manner that a flow passage 7 is provided to penetrate a valve seat disposed in a valve seat case 5 and a moving side housing 8 is provided to face the opening end surface of the valve seat. In the housing 8, the moving side valve member 9 is disposed to fact the opening part of the circular flow passage 7 of the valve seat by pressing it in a valve seat direction with a coil spring 10. In this case, one or both of the moving side valve member 9 and the valve seat constituting the check valve are made of elastic high- molecular materials.  Thus, even when the moving side valve member 9 and the valve seat are repeatedly contacted with and disconnected from each other, damage to contact parts between both is prevented by an impact softening effect and even if small damage occurs, fluid leakage is prevented by an elastic pressing force.
