摘要： The invention relates to an internal gear pump (1), comprising axial discs (16) for lateral sealing, and a separating piece (7) configured to separate a suction area (8) from a pressure area (9) in a pump room (6), and which is also referred to as a sickle. In order to keep the separating piece (7) from co-rotating with the gears (2, 3) of the internal gear pump (1) during low or non-existent counter-pressure in the pressure area (9), according to the invention a fixation (18) is formed by way of bonding points on the axial discs (16), which retains the separating piece (7).

摘要： The invention relates to an internal gear pump having a sickle-shaped separator (7) which, in a sickle-shaped pump chamber between an internal gear and a pinion of the internal gear pump, separates a suction region (8) from a pressure region (9). The invention proposes that pilot control ducts (16) be provided in the outer side and in the inner side of the separator (7), which pilot control ducts are open at the pressure-region-side end, that is to say communicate with the pressure region, and taper and end counter to a delivery direction of the internal gear pump. The pilot control ducts (16) effect a continuous pressure rise in tooth spaces of the internal gear and of the pinion from the suction to the pressure region (8, 9), and prevent an abrupt pressure rise at the pressure-region-side end of the separator (7).
摘要翻译：本发明涉及一种具有月牙形状的切削件（7），该分离的抽吸区域的内齿轮泵中的环形齿轮和所述内啮合齿轮泵的小齿轮之间的月牙泵室的压力区域（9）（8）。本发明提出了在分离器（7）导频信道（16），其在打印区域侧的端部开放的，D的外侧和内侧提供。小时。与压力范围进行通信，并朝向内齿轮泵和端部的传送方向逐渐变细。导频信道（16）使在所述环形齿轮的齿间空间的连续压力增加与小齿轮从吸入到压力区域（8,9），并且避免在分离器（7）的压力区域侧的端部的突然的压力增加。
