Patent DE-4136109-A1 (DE)
IPC: B60T8/175
Filed: 1991-11-02
Abstract: In a regulated slip brake system which operates on the feedback principle in anti-blocking mode and is fitted with a self-priming pump (9), fast response of the wheel brakes is to be facilitated in drive slip control mode without the use of a high-pressure reservoir. This is achieved by a specially designed low-pressure reservoir (6) which has a separate intake channel (7, 8) on the intake side of the pump for the anti-blocking (ABS) and drive-slip control (ASR) modes, whereby only partial draining of the low-pressure reservoir (6) via the ABS intake channel (7) is possible up to a defined permanent ready-use volume (x), since then a valve (24, 25) controlled by the piston travel closes. This ready-use volume (x) is available to the intake side of the pump (9) under slight intake pressure via the ASR intake channel (8) to be electromagnetically opened at the start of drive slip control, thus avoiding long intake distances.
