    Abstract: The present invention relates to a rotary fuel pump (101). The pump (101) has a rotor (107) and at least one pumping element (115) for supplying high pressure fuel. A cam box (123) containing a cam arrangement (103) is provided for actuating the at least one pumping element (115). A speed dependent fuel pressure line (129) is provided for supplying speed dependent fuel pressure to an advance arrangement (125) for adjusting the timing of fuel delivery by the pump (101). A first vent line (131) is provided for venting air from the speed dependent fuel pressure line (129). The first vent line (131) is in fluid communication with a collection chamber (137) for collecting air vented from the speed dependent fuel pressure line (129). A second vent line (141) is provided for venting air from the collection chamber (137). The second vent line (141) is a helical groove (141) formed in the rotor (107) or a pump housing (105). The present invention also relates to a rotor (107) for a fuel pump (101).

    Abstract translation: 本发明涉及一种旋转燃料泵(101)。 泵(101)具有用于供应高压燃料的转子(107)和至少一个泵送元件(115)。 提供了包含凸轮装置(103)的凸轮箱(123),用于致动所述至少一个泵送元件(115)。 提供速度依赖燃料压力线(129),用于将速度相关的燃料压力提供给用于调节泵(101)的燃料输送定时的提前装置(125)。 提供第一排气管线(131),用于从速度依赖燃料压力管线(129)排出空气。 第一排气管路131与收集室(137)流体连通,用于收集从速度依赖燃料压力管线(129)排出的空气。 第二排气管(141)用于从收集室(137)排出空气。 第二排气管线(141)是形成在转子(107)或泵壳体(105)中的螺旋槽(141)。 本发明还涉及一种用于燃料泵(101)的转子(107)。
