Abstract (en)
[origin: US4631005A] In a control device for limiting the maximum permissible input torque or power for a hydraulic pump, a control valve is provided with a first piston area which is acted upon by pressure from a torque sensor. A second piston area effective to more the control valve against a return means is acted upon by pressure from a remote control device so as to reduce the maximum possible input torque and thus create an input torque control device also effective as a power preselecting device.
