Abstract
An electrohydraulic unit for pressure control in automotive vehicle brake systems includes a housing, wherein channels and accommodating bores for inlet and outlet valves, pressure accumulator, pump, pump valves, pump drive and pressure fluid ports are incorporated, wherein accommodating bores for the inlet and outlet valves open vertically into a first housing plane, and accommodating bores for the pump and the suction channel of the pump are arranged in a second housing plane disposed in parallel to the first housing plane, and the suction channel is connected to an accommodating bore of the pressure accumulator which extends both in the area of the first and the second housing planes. Both the suction channel and the pressure channel are positioned on a joint axis in the second housing plane, and both the suction valve and the pressure valve are arranged in the second housing plane coaxially one behind the other in the area of the suction and pressure valves.
