    • The fluid pump has an impeller (10), provided with vanes (12) and driven to rotate in a pump chamber. The pump chamber is defined in the direction of the pivot axis (18) of the impeller (10) by wall parts (24), in each end face (25) of which toward the impeller (10) there is one annular feed conduit (32). An intake opening discharges in the region of the beginning of the feed conduit of one wall part, and an outlet opening (34) discharges in the region of the end of the feed conduit (32) of the other wall part (24). The outlet opening (34) is embodied as elongated in the circulation direction (11) of the impeller (10), and in the radial direction with respect to the pivot axis (18) of the impeller (10), it has a width (b) that is less than the width (B) of the feed conduit (32) in the radial direction. Instead of the elongated outlet opening (34), it is also possible for a plurality of separate outlet openings to be provided, which are offset from one another in the circulation direction (11) of the impeller (10).
    • 流体泵具有设置有叶片(12)并被驱动以在泵室中旋转的叶轮(10)。 泵室通过壁部分(24)在叶轮(10)的枢转轴线(18)的方向上限定,在其每个端面(25)中朝向叶轮(10),存在一个环形进给导管 32)。 吸入口在一个壁部分的进料管道的开始区域中排出,并且出口开口(34)在另一个壁部分(24)的进料管道(32)的端部的区域中排出。 出口开口(34)被实施为在叶轮(10)的循环方向(11)上细长并且在相对于叶轮(10)的枢转轴线(18)的径向方向上具有宽度( b)小于馈送导管(32)在径向方向上的宽度(B)。 代替细长的出口开口(34),也可以设置多个单独的出口,其在叶轮(10)的循环方向(11)上彼此偏移。

    • A pumping unit having a pump chamber in which a rotor is mounted in a rotatable manner, and which is formed by a circumferential wall and two end walls, is already known. The circumferential wall is formed on an annular collar of a pump part and, on the inside, forms a track on which sealing bodies of a rotor roll. The track of the pump chamber is subjected to high compressive loading which, if the pump part is made of plastic, may result in the track rupturing. In the case of the pumping unit according to the invention, the pump part is improved in respect of strength and service life. Deformation of the pump part by hydraulic forces or by pressing-in forces is avoided. The invention provides that ribs are arranged on the outside of the circumferential wall, the outside being directed away from the pump chamber, or that arranged on that side of the end wall which is directed away from the pump chamber is at least one shoulder which is connected in a force-fitting manner, by means of a press fit, to the pump housing and is designed with thin walls to the extent where the pressing forces do not result in any deformation to the end wall of the pump chamber.
    • 具有可旋转地安装有转子并且由周向壁和两个端壁形成的泵室的泵送单元是已知的。 圆周壁形成在泵部件的环形套环上,并且在内侧上形成有转子卷轴的密封体的轨道。 泵室的轨道受到高压缩负荷,如果泵部分由塑料制成,则可能导致轨道破裂。 在根据本发明的泵送单元的情况下,泵的部件在强度和使用寿命方面得到改进。 通过液压力或压入力避免泵部件的变形。 本发明提供的肋条布置在圆周壁的外侧上,外部远离泵室,或者设置在远离泵室的端壁的该侧的至少一个肩部 通过压力配合方式以压配合的方式连接到泵壳体,并且被设计成具有薄壁,其压力不会导致对泵室的端壁的任何变形。
