Pressure-limiting valve |
摘要 |
A pressure-limiting valve comprises a cylindrical actuator piston guided displaceably in a bore and held under the pressure of a spring in the closure position of the valve. Longitudinally-directed throughflow passages are formed in the actuator piston on the pressure-loaded end and are arranged concentrically with respect to the central axis and open into an annular groove extending around and in the circumferential surface of the actuator piston. This groove is sealed off by a gasket mounted in the bore wall. When the set pressure predetermined by the closure spring is exceeded, the actuator piston travels with the gasket over the annular groove so that the pressure medium can flow away through the outlet opening.
