Summary: | A mechanical automotive vacuum pump includes a housing with a housing cylindrical bearing surface. A pumping chamber is arranged in the housing. A pump rotor which includes a rotor body having a rotor body bearing section and a chamber section is rotatably supported by the housing. A radial vane slit is arranged at the chamber section. A rotor body cylindrical bearing surface is arranged at the rotor body bearing section. The rotor body bearing section includes a circular lubrication ring groove. A radially shiftable pump vane is supported in the radial vane slit. A friction bearing is defined by the rotor body cylindrical bearing surface and the housing cylindrical bearing surface. The housing cylindrical bearing surface includes a lubrication inlet opening which lies in a same transversal plane as and opposite to the circular lubrication ring groove. The lubrication inlet opening is directly connected to a lubricant pump connector. |
