    • At sufficiently high pressure in a closed container, filling of, or discharge from the pneumatic suspension of a motor car is controlled by a level switch whose positions represent different relative positions between a chassis and wheel shafts of a motor car, depending on a load variation. When the pressure in the container drops, a pressure responsive switch causes a control valve to connect the pressure conduit and the suction conduit, of a compressor with the closed container and the outside air, respectively, unless the level switch is operated by load variation. Below a minimum pressure in the container, charging by the container is continued even if the level switch is operated.
    • 在密闭容器中的足够高的压力下,通过液位开关来控制电动汽车的气动悬架的填充或排出,其位置表示机动车的底盘和车轮轴之间的不同相对位置,这取决于负载变化 。 当容器中的压力下降时,压力响应开关使得控制阀分别将压缩机的压力管和吸入管与密封容器和外部空气连接,除非液位开关由负载变化操作。 在容器内的最小压力以下,即使操作液位开关,容器仍能继续充电。

    • A coiled strip of filter material includes a pair of superimposed longitudinally coextensive strip portions each having a longitudinally extending free edge and a transversely spaced connected edge connected with the respectively other strip portion. A plurality of at least substantially parallel transverse corrugations is provided in only one of these strip portions and the convolutions of the coiled strip define with one another two spirally intercalated internal filter chambers one of which is open at one axial end of the coil and the other of which is open at the other axial end of the coil.

    • A sealing structure for a system which rotates a driven coupling member in a contaminated compartment has a sleeve which extends into an opening of a wall of the cell defining the contaminated compartment and has an internal annular shoulder sealingly engaging an external shoulder of the driven coupling member in the compartment. The driven coupling member has an axial bore which is sealed from the contaminated compartment and can receive a torque-transmitting part of a second coupling member which is located without the compartment and is driven by a motor through the intermediary of a clutch. The sleeve is in sealing engagement with the wall, and the likelihood of leakage between the sleeve and the driven coupling member is further reduced by the provision of one or more packings, U-rings and/or liquid seals. The two shoulders bear against each other to prevent leakage of contaminating matter from the compartment when the second coupling is detached. The opening in the wall is evacuated prior to detechment of the second coupling member and remains evacuated until after attachment of a fresh second coupling member.
    • 用于使受污染隔间中的从动联接构件旋转的系统的密封结构具有延伸到限定污染隔室的单元的壁的开口中的套筒,并且具有密封地接合从动联接构件的外肩部的内部环形肩部 在隔间。 从动联接构件具有轴向孔,所述轴向孔与被污染的隔室密封并且可以容纳第二联接构件的扭矩传递部分,该第二联接构件位于没有隔室的位置,并且由电动机通过离合器驱动。 套筒与壁密封接合,并且通过设置一个或多个密封件,U形环和/或液体密封件,进一步减小了套筒和从动联接构件之间泄漏的可能性。 两个肩膀相互抵靠,以防止第二个联轴器脱离时污染物质从隔间泄漏。 在第二联接构件被拆除之前,将壁中的开口抽真空并保持抽空,直到附接新的第二联接构件。
