Abstract

An autochecking arrangement for a hydraulic system, which includes an actuating piston displaceable under the action of a pressure source and controllable as to displacement independently of the pressure of the pressure source by a valve arrangement, comprises a pressure sensor connected into the hydraulic system and emitting signals corresponding to at least two sensed pressure thresholds, a switching system for providing sequentially different actuation states of the hydraulic system and a monitor for monitoring the correct actuation of the hydraulic system in cooperation with the signals from the pressure sensor.
