    Abstract: The invention concerns a reverse osmosis system (1) with at least one membrane unit (2) comprising an inlet (3), a permeate outlet (4) and a concentrate outlet (5), a high-pressure pump (8) that is connected to the inlet (3), a pressure exchanger (11) comprising at least one high-pressure concentrate connection (HPC), and a booster pump. It is endeavoured to achieve the lowest possible energy consumption. For this purpose, the booster pump is made as a displacement pump (16) that is arranged between the concentrate outlet (5) and the high-pressure concentrate connection (HPC) of the pressure exchanger (11).

Date Jun. 23, 1994A steering system for vehicles or ships is provided, with a steering handwheel and a steering element with no mechanical linkage line therebetween, with a steering handwheel sensor device, a steering element sensor device and a control arrangement which, in dependence on the output signals of the sensor devices, operates an electromechanical transducer, on the output side of which the steering element is arranged. It is desirable to increase the reliability of such a steering system For that purpose, the control arrangement comprises at least two independent control units, and a fault-monitoring device is provided which precludes a defective control unit from influencing the steering element.

    Abstract: A hydraulic system is proposed, with a pressure source (P), a pressure sink (T), a work motor (4), a main valve (3) which is arranged between the pressure source (P) and the pressure sink (T) on the one hand and the work motor (4) on the other hand and is connected to the work motor (4) by way of work connections (73, 74), and a compensating valve (2) between the pressure source (P) and main valve (3) and an additional valve arrangement (5) between the main valve (3) and the pressure sink (T), which controls the volume flow from the main valve to the pressure sink (T). In a system of that kind it is desirable to provide better control facilities. To that end, the valve arrangement (5) has an externally controllable degree of opening.

    Abstract: A valve (10) is specified, having a closing member (2), co-operating with a valve seat (11), said closing member (2) and said valve seat (11) each having in their contact area a closing surface (16, 17), which bear against each other in the closed state. With such a valve the improvement of the tightness must also be possible, even with a simple construction. For this purpose one of the closing surfaces (16, 17) is coated with a coating material (18), which is softer than the material of the other closing surface.
