摘要: A drive for a feed valve having an actuating line and a device for controlling the pressure in the actuating line. The device comprises three valves connected to one another to form a hydraulic auctioneering circuit. The drive is suitable for a comparatively high oil pressure, and the drive is provided with a test system which monitors the operativeness of the drive. The test system is pressurized by the device, and a pressure drop can be sensed in the test system by a sensor.

摘要: This hydraulic valve has a housing (2) with a feed line (12) and a discharge line (14) for a fluid. A sealing point is provided between the feed line and discharge line. A spring acts in the closing direction on the sealing point via a piston.The aim is to create a hydraulic valve which requires no additional energy source. This is achieved when the piston (8, 23) can be moved in the opening direction merely by a total of the pressures present in the feed line (12) and in the discharge line (14).

摘要: The switch element for triggering a cut off or control function is accommodated in a shaft (1), for example of a speed monitor. A spring-loaded release bolt (2) is surrounded coaxially by a compensating bush (4) which has a compensating ring (15), a spring plate (13) and a hub tube (14) and the center of gravity (S.sub.Kb) is such that, when the shaft (1) rotates, it compensates the centrifugal force, acting as an additional force to the spring prestressing force, of the spring half adjacent to the spring plate (13) and having the center of gravity (S.sub.F/2).
