    • A pumping apparatus includes a gear pump (16) in fluid communication with a boost pump. The gear pump (16) includes a pump housing (28), a first gear (30), and a second gear (32). The first and second gears have gear teeth and trunnions (26,34) on opposite sides thereof, and are disposed in the pump housing (28). The gear teeth of the first and second gear are meshed in a mesh region (52). An inlet cavity (58) is defined adjacent to the first and second gears, on one side of the mesh region (52). A pump outlet (60) is defined on an opposite side of the mesh region (52) from the inlet cavity (58). A bearing (36,38) is configured to support at least one trunnion (26,34) of the first gear and/or the second gear. A bearing interface (40) is defined between the bearing and the at least one trunnion. A flow path (68) is defined between the bearing interface (40) and the inlet cavity (58).
    • 泵送装置包括与增压泵流体连通的齿轮泵(16)。 齿轮泵(16)包括泵壳体(28),第一齿轮(30)和第二齿轮(32)。 第一和第二齿轮在其相对侧上具有齿轮齿和耳轴(26,34),并且设置在泵壳体(28)中。 第一和第二齿轮的齿轮啮合在网状区域(52)中。 在所述网状区域(52)的一侧上,限定与所述第一和第二齿轮相邻的入口腔(58)。 泵出口(60)限定在与入口腔(58)相对的网状区域(52)的相对侧上。 轴承(36,38)构造成支撑第一齿轮和/或第二齿轮的至少一个耳轴(26,34)。 轴承接口(40)被限定在轴承和至少一个耳轴之间。 流动路径(68)被限定在轴承接口(40)和入口腔(58)之间。

    • An internal gear pump includes a ring gear and a pinion configured to mesh with the ring gear. The ring gear and pinion delimit a pump chamber extending from a suction region to a pressure region. The internal gear pump also includes an axial disk arranged on front faces of the ring gear and the pinion and includes a lubricant feed from the suction region between the axial disk and the ring gear and pinion. The lubricant feed includes a lubricant channel which passes through the axial disk. A wedge gap is delimited between the axial disk and the ring gear and pinion. The wedge gap communicates with the suction region and, when the ring gear and the pinion are driven in rotation, a lubricating film forms between the axial disk and the ring gear and pinion.
    • 内齿轮泵包括齿圈和与齿圈啮合的小齿轮。 环形齿轮和小齿轮界定从抽吸区域延伸到压力区域的泵室。 内齿轮泵还包括布置在齿圈和小齿轮的前表面上的轴向盘,并且包括从轴向盘和齿圈和小齿轮之间的抽吸区域的润滑剂供给。 润滑剂供给装置包括穿过轴向盘的润滑剂通道。 楔形间隙在轴向盘和环形齿轮和小齿轮之间界定。 楔形间隙与抽吸区域连通,并且当齿圈和小齿轮被驱动旋转时,在轴向盘和齿圈和小齿轮之间形成润滑膜。
