    • The invention relates to an impeller for a pump, particularly for a cooling water pump of an internal combustion engine, comprising a hub (11), a cover disk (14) which is disposed on the intake side and is provided with a central opening (15) for sucking in a conveyed medium, and at least one blade (13) that is connected to the cover disk (14) located on the intake side so as to form a single piece therewith and is provided with an inner section (13a) located in the region of the central opening and an outer section (13b) located in the region of the cover disk (14). The aim of the invention is to obtain a high degree of efficiency while keeping the production simple. Said aim is achieved by embodying the impeller (5) in a completely open manner on the pressure side lying opposite the cover disk (14) and by configuring the inner section (13a) of the blade (13) in a three-dimensionally bent manner while configuring the outer section (13b) thereof in an essentially two-dimensionally bent manner.
    • 本发明涉及一种用于泵的叶轮,特别是一种用于内燃机的冷却水泵的叶轮,包括轮毂(11),盖板(14),其设置在进气侧并设置有中心开口 15),以及至少一个叶片(13),其连接到位于进气侧的盖盘(14)以便与其形成单件,并且设置有内部部分(13a) )和位于所述盖盘(14)的区域中的外部(13b)。 本发明的目的是在保持生产简单的同时获得高效率。 所述目的通过在与盖盘(14)相对的压力侧上以完全打开的方式实现叶轮(5)并且通过将叶片(13)的内部部分(13a)以三维弯曲 同时以基本上二维弯曲的方式构造外部部分(13b)。
