  • Patent number: 10174821
    Abstract: The invention relates to an electrohydraulic actuator comprising a hydraulic piston, a spindle drive for moving the piston along an axis of rotation, wherein the spindle drive comprises a spindle and a nut, and a worm wheel, which is coaxially attached to the nut. Furthermore, an electric motor having a worm, which meshes with the worm wheel, is provided. The nut is radially and axially supported by means of a bearing. In addition, there is a single-armed rotation-prevention mechanism in order to prevent the spindle from rotating. An angle with respect to the axis of rotation is included between a point of action of the worm on the worm wheel and the effective direction of the rotation-prevention mechanism, wherein the angle is selected in such a way that, for a predetermined torque acting on the nut, a radial force acting on the piston is minimized.

  • Publication number: 20080210511
    Abstract: The invention relates to a switchable clutch which requires control power merely for switching from one operating state to another. The clutch is particularly suitable for connecting and disconnecting auxiliary units in internal combustion engines and motor vehicles. The clutch according to the invention has a driving element (9), which is rotationally fixed to a shaft (3) and a clutch disk (5) which is operatively connected to the auxiliary unit, at least one toggle lever (23) being rotatably mounted on the driving element (9), axial displacement of a control sleeve (33) causing it to engage with a first end (29) of the toggle lever (23) so that a second end (29) of the toggle lever (23), as a function of the position of the control sleeve (33), becomes operatively connected to the clutch disk (5), thereby closing or opening the clutch.

  • Patent number: 7288605
    Abstract: A method and apparatus for the removal of free, emulsified, or dissolved water from liquids of low volatility, such as oil, is shown. The liquid of low volatility is removed by contacting the fluid stream of concern with one side of a semi-permeable membrane. The membrane divides a separation chamber into a feed side into which the stream of fluid is fed, and a permeate side from which the water is removed. The permeate side of the chamber is maintained at a low partial pressure of water through presence of vacuum, or by use of a sweep gas.
