<P>PROBLEM TO BE SOLVED: To provide a means for mounting a check valve to a housing having a fluid path therein, capable of securing a closing property between a valve element and a valve seat by preventing the deformation of the valve seat, and of securing the flow amount of fluid required for a start by preventing the rattling of the check valve relative to the housing having the fluid path therein. <P>SOLUTION: The check valve 10 and a wave washer 54 are put in a housing space 52 of the housing 46 having the fluid path therein, and the check valve 20 and the wave washer 54 are prevented from coming out of the inside of the housing space 52 by removal preventing means 58, 62. In a state where the check valve 10 and the wave washer 54 are mounted within the storage space 52, repulsive force is applied to the wave washer 54. The wave washer 54 absorbs the vibration of the check valve 10 due to its valve operation to reduce an impact on the valve seat 24 and prevent the occurrence of rattling between the housing 46 and the check valve 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
