An anti-locking brake system for a land vehicle, which is set up in particular for traction control and vehicle dynamics control, comprises a pump ( ) for actuating a wheel brake ( ) which removes brake fluid from a brake pressure generating unit ( ) and supplies it to the wheel brake ( ), wherein a first valve arrangement ( ) blocks in a non-actuated (normal) position ( ) the connection between the brake pressure generating unit ( ) and an input connection ( ) of the pump ( ) and in at least one actuated position ( ) establishes a primary flow connection (A), a first electromagnetic valve ( ) establishes in a non-actuated position ( ) the connection between an output connection ( ) of the pump ( ) and the brake pressure generating unit ( ), and blocks it in an actuated position ( ), a second electromagnetic valve ( ) blocks the connection between the wheel brake ( ) and the input connection ( ) of the pump ( ) in a non-actuated position, and in an actuated position establishes it, and a third electromagnetic valve ( ) establishes the connection between the output connection ( ) of the pump ( ) and the wheel brake ( ) in a non-actuated position ( ) and blocks it in an actuated position ( ). To generate a more accurate pressure modulation during the operating phase &ldquo;maintain pressure&rdquo; (II), the third electromagnetic valve ( ) is in the actuated position during said operating phase.

Anti-locking brake system for a land vehicle

A hydraulic control unit for a motor-vehicle braking system includes a pump ( ) delivering hydraulic fluid under pressure, the pump being capable of being controlled by an electronic control unit (ECU) and supplying the hydraulic fluid for at least one braking device ( ) which is coupled to a wheel of the vehicle, and also a first reservoir ( ) for pressureless hydraulic fluid, which is assigned to the pump ( ) on the input side, and a second reservoir ( ) for hydraulic fluid under pressure, which is assigned to the pump ( ) on the output side. In order to design the control unit for good packaging and installation space considerations, the pump ( ), the first reservoir ( ), and the second reservoir ( ) are arranged in a common casing ( ), and integrated as an electrohydraulic modular unit.

Hydraulic control unit for a motor vehicle braking system

The present invention relates to a brake actuation unit comprising a cylinder/piston arrangement which acts on at least one brake lining which can be brought into frictional engagement with a brake disk, a hydraulic pump which is hydraulically connectable with a pressure chamber of the cylinder/piston arrangement in order to move the cylinder of the cylinder/piston arrangement relative to the piston of the cylinder/piston arrangement, and a motor for driving the hydraulic pump.
