摘要： A restriction valve device for fluid under hydraulic pressure in the shock-absorbing mechanism for vehicles comprises a seat member (10) valve with at least onemain opening (4) for passing the pressurized fluid, said main opening ( 4) closable by avalve body (5) movable spring-biased, and at least one auxiliary opening (7) for thepressurized fluid, said auxiliary opening being selectively closed by a closure member (2).In order to obtain an order or for rapid and reliable changes in the functional
characteristics of the damper, however, simple and economical way, a variable enclosedspace (11) is delimited by the seat member (10) and the valve body (5) valve. The auxiliaryopening is connected with the closed space to admit fluid under pressure when theclosure member is opened, thereby also applying the pressure of fluid on the body (5)valve to increase the strength of the pressure exerted on the body against the force ofthe tension spring and thereby change the functional characteristics of the restrictionvalve device.
