Date Apr. 20, 1989.In order to avoid energy losses, particularly in the case of actuating operations characterized by energetic cycles, it is suggested to insert a double-lever cam-and-roller transmission mechanism between a hydraulic accumulator and a hydraulic pressure consumer which mechanism has the effect that the accumulator pressure and the consumer pressure are always balanced. The consumer is therefore actuatable by means of slight control forces, the energy used thus remaining at a minimum. Thus, only the slight actuating energy of the control forces and the unavoidable hysteresis loss of the system need to be compensated for. |
