Patent DE-4021655-A1 (DE)
Title: Antilocking and antislip braking installation - has hydraulically-operated inlet valves which remain open for wheel-spin correction
Inventor: BURGDORF JOCHEN
IPC: B60T8/42
Filed: 1990-07-07
Abstract: The inlet valves (2,3) for the wheel-brakes are operated hydraulically while the venting valves (4,5) are electro-magnetic. The inlet valve (2) for the drive wheels is operated by both the master brake cylinder pressure and the servo pressure. This ensures that the valve is reduced to the control level when both systems operate, i.e. for braking, while for wheel-spin control only the servo pressure operates and the valve remains open. The undriven wheels' inlet valve is operated only by the servo pressure and closes when the ABS operates and when wheel-spin correction is applied, i.e. the undriven wheels are not braked for wheel-spin control. USE/ADVANTAGE - Simple wheel-spin control in ABS system; uses simple inlet valves.

Abstract: An electrical power-supply device 1 for very-low-voltage DC loads, for example DC motors of air-conveyor devices and for window and door fitting actuating drives is described, which consists of photovoltaic elements 2 (solar panels) and an accumulator 3 on which said elements 2 act and which is connected upstream of the load as a buffer device.   In order that the accumulator can be maintained in a charge state which ensures the correct operability of the DC load in all circumstances, a mains-powered transformer 4 is allocated to the accumulator 3 in addition to the photovoltaic elements 2. In this case, the accumulator 3 can be connected to the photovoltaic element 2 and/or to the secondary part of the transformer 4 via a charging regulator 5 which, in turn, can be switched over between three different switching states, as a function of the charge state of the accumulator 3. In this case, the one switching state connects the photovoltaic elements 2 and the transformer 4 in parallel with one another to the accumulator 3, while the second switching state isolates the transformer 4 from the accumulator 3, and the third switching state also isolates the photovoltaic elements 2 from the accumulator 3. <IMAGE>
