    • The invention relates to a displacement pump for delivering pressure medium to a consumer, in particular to an assisted steering system for motor vehicles. A pump stack (2) having a rotor (3), a cam ring (4) and a plurality of working slides (5) is inserted in the interior of a housing (1), which is closed axially on one side with a cover (7). Working chambers (6), which are divided by the working slides (5) and are delimited in the axial direction by control plates (9), are formed between the cam ring (4) and the rotor (3). Supply kidneys (10, 11) for supplying oil to the working slides (5) and the working chamber (6) are formed in the end faces, which face the rotor (3), of the control plates (9). An annular web (19) is situated between the supply kidneys (10, 11) and a bore (20) for a drive shaft (13). At least one of the supply kidneys (10, 11) is provided with at least one oil pocket (18). The at least one oil pocket is arranged such that it protrudes at least partially into the web (19).
    • 本发明涉及一种用于压力介质泵送到消费者,尤其是动力转向用于机动车辆的正排量泵。 内部的壳体(1),它是由一个盖轴向封闭在一侧(7),泵封装(2),其具有转子(3),凸轮环(4)和多个工作载玻片(5)的被插入。 所述凸轮环(4)和转子(3)由工作幻灯片之间(5)分割(6)形成的作用腔,它们在轴向方向上由控制板包围(9)。 在与转子(3)的面向所述控制板的前侧(9)(5)和所述工作腔(6)形成为用于工作滑动供给油肾供应(10,11)。 供应肾脏(10,11)和一个通孔(20),用于驱动轴(13)之间是一个环形腹板(19)。 至少一个供应肾脏的(10,11)设置有至少一个油兜(18)。 所述至少一个油腔(18)被布置成使得它至少部分地伸入到所述幅材(19)。
