Inventor: TOWNEND RICHARD
IPC: B60G23/00
Filed: 1992-04-16
Abstract: A vehicle suspension system has hydraulically extensible and contractable actuators 14 connected between the vehicle body and the wheel assemblies 17. The actuators 14 are controlled by valves 25 to control the vehicle attitude. The valve 25 of each of the actuators 14 is controlled by a first device such as a digital processor 100, 200, 300 and 400 respectively which is individual to the respective actuator and a second device such as a digital processor 500 which controls all of the actuators 14. Signals generated from the first and second devices are combined to form control signals for each actuator 14. Signals from the second device 500 are filtered before being combined with those from the first device 100, 200, 300 or 400 to remove signals from the second device 500 that are outside a particular band width. The filtering means may be adjustable to set the band width of frequencies above which signals from the second device are removed.

Patent DE-4300585-A1 (DE)
Inventor: SCHENK RUDOLF
IPC: C02F9/00
Filed: 1993-01-13
Abstract: A liquid treatment plant has several appliances (3, 4, 5) connected in parallel for handling the liquid. These appliances (3, 4, 5) can have different cross-sections. Of three appliances, two (4, 5) are connected in series with one valve device (6, 7) each. These valve devices (6, 7) act as hydraulic limit-value switches and have a valve body (19a, 19b) which is preloaded by a spring and closes the passage through the valve device (6, 7) in its inoperative state. Up to a certain liquid consumption, the liquid flows solely through one appliance (3). As soon as the demand for liquid exceeds a predeterminable value, the pressure difference arising between inlet and outlet of the appliance (3) opens one of the two valve devices (7) so that the liquid flows through a second appliance (5). If the consumption increases still further, the second valve device (6) also opens at a certain pressure drop. Such a design of the liquid treatment plant ensures that liquid passes through the individual appliances (3, 4, 5) as a function of the liquid consumption and that the individual appliances (3, 4, 5) consequently have good efficiency. <IMAGE>
