Abstract (en)

[origin: DE19828963A1] The hydraulic switch system to control at least one low-load and one high-load operating unit (4,6), with a setting pump (2), has a bypass (32) which links the outlet from the measurement diaphragm through the pressure scales (16a) to at least one connection for the low-load operating unit (6). The measurement diaphragm (14a,14b) is formed by a proportional valve, so that the operating connections can be linked to the connections at the pump or tank. The bypass (32) is controlled according to the position of the valve slide at the proportional valve.
