PCT No. PCT/DE96/01524 Sec. 371 Date Sep. 29, 1997 Sec. 102(e) Date Sep. 29, 1997 PCT Filed Aug. 16, 1996 PCT Pub. No. WO97/21570 PCT Pub. Date Jun. 19, 1997A vehicle hydraulic brake system having brake pressure modulation valve assemblies, between a dual-circuit master cylinder and wheel brakes of vehicle wheels. The pump device is embodied as a low-pressure pump with the brake pressure modulation valve assemblies be assigned a first and second return pump and that in the automatic braking mode the first pressure chamber is made to communicate with a first return pump and the second pressure chamber is made to communicate with the second return pump, on the inlet side in both cases. The low-pressure pump, in the automatic braking mode, generates charge pressure for the return pumps that is substantially below a maximum brake pressure, and the return pumps generate the maximum projected brake pressure and serve, in the additionally possible anti-lock mode, to return pressure fluid from the wheel brakes to the master cylinder. The vehicle brake system is an inexpensive low-pressure pump that offers a high possible capacity of the return pumps in the automatic braking mode. |
