The programmable setpoint storage device 136 can, for example, be a variable diode function generator known from now on, ie it will emit a programmed series of pulses. Such a function generator can be programmed in Reohon machine technology that is customary today by means of analog-digital converting or direct digital input and allows the storage of a correspondingly entered program. The reap from dioaem SoeichergerHt.

Depending on the selected operating mode, one of the two pressure regulating valves 45 «46 determines the pressure medium reduction of the piston 22 in the power drive 20. Following this application, the piston 20 and thus the plant 10 are displaced. This shift also leads to a shift of the endless belt 146 rigidly connected to it via the deflection roller 142 and the drive wheel 143 of the pulse generator 145, so that depending on the shifting displacement, it emits a series of pulses of greater or smaller pulse density per unit of time. Given a suitable relationship between the linear displacement travel bu angle of rotation and the design of the pulse generator 145 with regard to the number of pulses per revolution, each pulse cannot be expressed as a distance. In the digital-to-analog converter 147, the pulse train

Za area of the idea is also the possibility of using the electrohydraulic · !! Pressure regulating valve similar to aeobftnieoh-hydreuliechen pressure regulating valve can be used directly in the differential separating door. For this purpose, the valve has a valve body with inlet and outlet channels and a valve body for changing the valve body through the valve reep. of the pressure gradient above the valve. A solo valve can either be switched directly into the hydraulic power input for power drive or into the control of a pressure regulating valve provided in such a power channel. Such a valve is arranged in such a way that, for example, the valve housing has the Kr .'- ftantr-.eb bsw. to which this movable work is arranged in a rigid movement connection and the Vsnt liqueur is moved along the Vsnt liqueur according to the programmed sword see e.g. duroh So ^!> ritteotor and spindle along the V.'eg- •• rsioh.
