真空泵
摘要：
本发明涉及机械式汽车真空泵(10)，具有壳体装置(9)，其包围泵送室(11)，并可旋转地支撑泵转子(16)，泵转子具有转子本体(22)，转子本体具有轴承区段(35)和腔室区段(36)。转子本体(22)在腔室区段(36)处具有径向轮叶狭缝(19)，其中，可径向偏移的泵轮叶(18)被支撑，在轴承区段(35)处，转子本体具有柱形轴承表面(39)，其与壳体装置(9)的柱形轴承表面(37)一起限定出摩擦轴承(38)。转子本体轴承区段(35)具有圆形润滑环槽(60)，壳体轴承表面(37)具有对应的润滑入口开口(6)，对应的润滑入口开口位于与环槽(66)相同的横向平面中，并与环槽(60)相对，入口开口(66)在真空泵(10)的壳体装置(9)处直接连接到润滑剂泵连接器(70)。
摘要（英）：

The invention refers to a mechanical automotive vacuum pump (10) with a housing arrangement (9) enclosing a pumping chamber (11) and rotatably supporting a pump rotor (16) with a rotor body (22) with a bearing section (35) and a chamber section (36). The rotor body (22) is at the chamber section (36) provided with a radial vane slit (19) wherein a radially shiftable pump vane (18) is supported. The rotor body (22) is at the bearing section (35) provided with a cylindrical bearing surface (39) which defines together with a cylindrical bearing surface (37) of the housing arrangement (9) a friction bearing (38). The rotor body bearing section (36) is provided with a circular lubrication ring groove (60) and the housing bearing surface (37) is provided with a corresponding lubrication inlet opening (66) lying in the same transversal plane as the ring groove (60) and opposite to the ring groove (60). The inlet opening (64) is directly connected to a lubricant pump connector (70) at the housing arrangement (9) of the vacuum pump (10).
