<p>This drive for a supply valve has an operating line (1) and a device for controlling the pressure in the operating line (1). The device comprises three valves (2, 3, 4) which are connected to one another to form a hydraulic 2-of-3 circuit. …<??>It is intended to create a drive for a supply valve, which is suitable for a comparatively high oil pressure and whose functional capability can be monitored by simple means. This is achieved by it being possible to apply pressure to a test system (14) via the device, and by it being possible to detect a pressure drop in the test system by means of a sensor. …<IMAGE>… </p> |
