ABSTRACT:
To limit the power output of a hydraulic assembly consisting of plural driven hydraulic motors, hydraulic pumps driving said motors, a single pump driving motor and control means for controlling the hydraulic flow to said drive hydraulic motors, a controller is provided which is supplied with an input signal from a subtractor which in turn is supplied with signals from a reference value setting device and an actual value setting device, the actual value setting device sensing the speed of the driving motor. An output signal of the controller is applied to all of the control means and is multiplied in each control means by a signal proportional to the setting of said control means, in order to obtain the flow control signal.
