The vibration reduction member (35) includes a sleeve (43) made from a rigid body, through which sleeve the connection member (42) is inserted, and an elastic member (45) surrounding an outer periphery of the sleeve (43). The elastic member (45) includes a tubular body (49) firmly fixed on an outer peripheral surface (44) of the sleeve (43) and an annular plate portion (50) projecting radially outward of the body (49). A fitting groove (58) of an outer peripheral edge portion (57) of the annular plate portion (50) is fitted on a peripheral edge (60) of an installation hole (59). A first and a second face (52, 53) of the annular plate portion (50) include recesses (54, 55), respectively. In the annular plate portion (50), a thin-walled portion (56) corresponding to a portion between bottoms of the recesses (54, 55) of the first and the second faces (52, 53) is formed.

摘要： PROBLEM TO BE SOLVED: To provide a relief valve for suppressing the self-exciting vibration of fluid to reduce noise. SOLUTION: The relief valve 1 comprises a valve element 7 stored in a valve housing 5, a coil spring 8 for energizing the valve element 7 to a first direction S1, and an elastic body 9 arranged inside the coil spring 8. When the valve element 7 is moved to a second direction S2 against an energizing force F1 of the coil spring 8 by a force F2 which the valve element 7 receives from a discharge oil path 2, a valve hole 17 is opened to escape a high pressure fluid to a low pressure side. The vibration of the coil spring 8 is propagated to the elastic body 9 via a receiving member 19 and damped. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To suppress self-excited vibration of a relief valve from being generated and make the relief valve inexpensive.
SOLUTION: The relief valve 3 is equipped with a cylindrical sleeve 10 for forming a valve hole 9 and a piston 11 slidably inserted in the valve hole 9 and energized in a closing direction F2. The piston 11 is a cup form and has a peripheral wall 11b and an end wall 11a. The peripheral wall 11b has an outer peripheral surface 11c slidably contacting with an inner surface 9a of the valve hole 9 and an inner surface 11d for receiving operating fluid pressure. In the case where the operating fluid pressure rises, the peripheral wall 11b is elastically expanded and friction with the inner surface 9a of the valve hole 9 increases. Hence, it is possible to suppress the piston 11 from generating self-excited vibration. In addition, suppression of self-excited vibration is realized by changing the form of the piston 11 to a cup form and increase of the number of parts is suppressed and thus the relief valve 3 can be made inexpensive.

摘要翻译：要解决的问题：抑制安全阀的自激振动的产生并使安全阀便宜。解决方案：安全阀3配备有用于形成阀孔9的圆柱形套筒10和可滑动地插入阀孔9并沿关闭方向F2通电的活塞11。活塞11是杯形，具有周壁11b和端壁11a。周壁11b具有与阀孔9的内表面9a滑动接触的外周表面11c和用于接收工作流体压力的内表面11d。在工作流体压力升高的情况下，周壁11b弹性膨胀，并且与阀孔9的内表面9a的摩擦力增加。因此，可以抑制活塞11产生自激振动。另外，通过将活塞11的形状变更为杯状，能够抑制自激振动的抑制，能够抑制部件数量的增加，能够使安全阀3成本低廉。版权所有（C）2007，JPO＆INPIT
