    • The invention relates to a lubricating device for a turbomachine with a main oil pump mechanically connected to a central rotor shaft, which main oil pump exhibits an input port or, respectively, an output port which is connected for fluid with a suction line or, respectively, a discharge line, and including a hydraulically driven oil pump unit, including a motor and a pump, disposed in the region of the oil container, which oil pump unit pumps lubricating oil from the oil container via a main supply line to the consumer points. The motor of the oil pump unit is driven by the oil flowing out of the discharge line of the main oil pump, and the pump is mechanically driven by the motor, and withdraws oil from the oil container. In order to create such a device or apparatus, it is disclosed that the main oil pump (4) and the motor (11) of the oil pump unit (10), where the output port of the oil pump unit (10) is connected to the suction line (6) of the main oil pump (4), together with the lines (6, 8) form a closed circulation placed under pressure. The pump (12) of the oil pump unit (10) pumps oil into the main supply line (21). The suction line (6) of the main oil pump (4) exhibits a connection line (28) with a pressure regulator (25) to the main supply line (21), as well as a discharge line (24), provided with a baffle, and running to the oil container (9), are provided for the balancing of the leakage losses and for the discharge of the occurring friction load output.
    • 本发明涉及一种用于涡轮机的润滑装置,其具有机械地连接到中心转子轴的主油泵,该主油泵分别具有输入端口或分别与吸入管路连接用于流体的输出端口,或者分别 ,排出管线,并且包括设置在油容器区域中的包括马达和泵的液压驱动油泵单元,该油泵单元将润滑油从油容器经由主供应管线泵送到消费点 。 油泵单元的电机由从主油泵排出管线流出的油驱动,泵由电机机械驱动,从油箱中取出油。 为了制造这样的装置或装置,公开了油泵单元(10)的输出端口与油泵单元(10)的主油泵(4)和马达(11)连接 与主油泵(4)的吸入管线(6)一起形成在压力下的封闭循环。 油泵单元(10)的泵(12)将油泵送到主供应管线(21)中。 主油泵(4)的吸入管线(6)具有与主供给管线(21)的压力调节器(25)的连接管路(28)以及排出管线(24) 挡板和运行到油箱(9),用于平衡泄漏损失和排出所产生的摩擦负荷输出。

    • A card index comprises a housing containing a drawer which holds a stack of punched cards. All the cards have punched holes in which a row of dogs in the bottom of the drawer engage and the cards also have punched selection holes in which selection stop cams can engage. Each card has selection holes in register with all of the stop cams except one. To select a card, a button corresponding to the card is pressed and this rocks a key lever to move the corresponding stop cam downwards. The cam passes through the selection holes in all the cards until it reaches the selected card which has no hole in register with that cam. Accordingly, the selected card and the cards, if any, below are pressed downwards and are held on the dogs. The drawer is released by depression of the button and is opened by a spring. As it opens, the drawer moves the cards which are pressed down on the dogs out of the housing with the selected card on top, but the cards above the selected card are retained in the housing by the stop cam. The arrangement has the great advantage over existing card indexes that it is not necessary to arrange the cards in any particular sequence in the stack in order for them to be correctly selected.
    • 卡片索引包括一个容纳一个夹持一叠打孔卡的抽屉的外壳。 所有的卡都有穿孔,其中抽屉底部的一排狗啮合,并且卡还具有穿孔选择孔,选择停止凸轮可以啮合。 每个卡都有一个与所有止动凸轮对齐的选择孔。 要选择一张卡片,按下与该卡片相对应的按钮,这样会摇动一个按键杆,将相应的停止凸轮向下移动。 凸轮通过所有卡中的选择孔,直到其到达所选择的卡,其中没有孔与该凸轮对齐。 因此,所选择的卡片和下面的卡(如果有的话)被向下按压并保持在狗上。 抽屉被按下按钮释放,并被弹簧打开。 打开时,抽屉将卡上的卡片从机壳中按下,将所选卡放在顶部,但所选卡上方的卡片通过止动凸轮保持在外壳中。 该布置与现有的卡索引相比具有很大的优点,因此不需要以堆栈中的任何特定顺序布置卡,以使它们被正确地选择。
