  • Patent number: 11473455
    Abstract: This disclosure relates to a control valve for a hydraulic camshaft phaser. The control valve includes a screw body having a cavity, a plurality of connections opening into the cavity, and a sleeve-shaped hydraulic guide element firmly inserted radially inside the cavity. At least part of the hydraulic guide element consists of plastic. The hydraulic guide element includes a plurality of pressure medium channels which open into its radial interior, each of which is connected to at least one of the connections. A control piston is displaceably accommodated in the hydraulic guide element, and, depending on the position of the control piston, connects the connections to each other. A sealing contour provided on a radial outer side of the hydraulic guide element contacts the screw body, sealing the pressure medium channels with respect to each other and/or with respect to axial ends of the hydraulic guide element.

  • Patent number: 11220188
    Abstract: A motor vehicle charging cable for DC voltage charging of an electrical energy store of a motor vehicle has a cable sheath that encloses conductors, such as first and second cooling-fluid-cooled electrical conductor for first and second DC voltage phases, a ground conductor or equipotential bonding conductor and/or at least one control conductor. Shaped elements are arranged between the cable sheath and the conductors at positions of the motor vehicle charging cable that are fixed in mounts. The shaped elements guide, clamp and restrict a relative movement between the conductors. The cable sheath restricts a relative movement between the conductors between those positions at which the motor vehicle charging cable is fixed in mounts.
