Patent DE-19830089-A1 (DE)
Title: Arrangement for controlling hydraulic system, esp. steering system
Inventor: BRENNER PETER
IPC: B62D5/065
Filed: 1998-07-06
Abstract: The arrangement switches on a charging device (2) if the pressure in a pressure storage device (1) falls below a lower value, and switches it off if the pressure exceeds an upper value, so that the pressure remains within a specified range. The transducers for driving the charging device are switching valves (3) arranged between the charging device and the pressure storage device. The charging device comprises a hydraulic oil pump and an electric motor. The pump acts as a hydraulic motor when the oil flow is reversed, in which case the electric motor is driven backwards and the induced negative voltage is the switch-on information for the charging device.
