Abstract

The device is connected by a constantly adjustable control valve arrangement with a pump and an expiration with a tank. The controller has in a basic position a rotating channel, which is connected with the tank and a rotating pressure limiter is provided. The position of the controller is on an accessible and controllable and a flow pipe for the argument supply of the consumer. The selector movement has an arranged expiration operational sequence (48, 50). The cross-section of the opening is independently adjustable of the control of the control valve (14). The load (2) has two connections, such as in each case an end throttle valve (48, 50) is provided. The device is a constantly adjustable 6-direction control valve (14).
