Abstract
The return pumps of brake systems with a precharging device are greatly stressed by the precharging pressure and subjected to premature wear. Significant leakage occurs in the long run which will damage the pump motors in the worst case. This is prevented by controlling the pressure fluid supply from the precharging source to the suction side of the return pump as a function of the pressure gradient in this connecting line. To this end, an electromagnetically operated on-off valve ( ) with a hydraulically insertable throttle is used.
