Abstract

A hydraulic unit, in particular for a controllable-slip vehicle brake system, includes a housing block, a pump, a first fluid duct, and a second fluid duct. The housing block defines a pump receptacle that receives the pump, which has a suction side and a pressure side. The first duct crosses the pump receptacle in a region of the pressure side of the pump. The second duct leads into the pump receptacle in the region of the pressure side. The first and second ducts are sealed off from each over via a separation point. The hydraulic unit is configured to enable contact with a damping device configured to damp pulsations and reduce operating noise of the hydraulic unit without negatively impacting functional properties of the hydraulic unit, in particular on pressure build-up dynamics of the vehicle brake system, or without jeopardizing a compact construction of the hydraulic unit.
