Abstract:
Electrohydraulic unit for pressure control in brake systems for automotive vehicles, comprising:a one-part housing including a plurality of parallel accommodating bores provided with control valves and disposed in pairs side by side in two rows in a first housing surface,parallel bores for forming pressure accumulators and damping chambers in a second housing surface which extends in the direction of the rows, and connecting bores for pressure fluid lines in a third housing surface, the said pressure fluid lines leading to a master and a slave cylinder of the brake system, wherein between the two rows of accommodating bores for the control valves there are arranged cylinder bores which extend in the direction of the rows and accommodate a piston and a valve of a pump,an accommodating bore for a pump drive, wherein the bores of the pressure accumulators are disposed between the bores of the damping chambers, wherein the accommodating bores for the control valves which are connected to a slave cylinder of one vehicle axle that have a volume requirement lower than the volume requirement of the slave cylinders of the other vehicle axle, have a smaller diameter and are arranged offset from the middle of the row in the direction of the third housing surface.
