A hydraulic unit includes a housing block, a pump receptacle formed on the housing block, and a pump element inserted into the pump receptacle. The pump element forms a separating point with the housing block. The separating point hydraulically separates low-pressure and high-pressure regions of the pump element. Known separating points are divided into sections. A first section forms a force closure between the housing block and pump element and a second section forms an axial stop where the pump element mechanically abuts the housing block. Pressure medium, under high pressure, from the high-pressure region can reach the section of the separating point forming the axial stop and cause corrosion. The section of the separating point forming the force closure faces the high-pressure region of the pump element to prevent access of pressurized pressure medium to the section of the separating point forming the axial stop and avoid corrosion. |
