Abstract: A valve arrangement for a motor vehicle has a valve plunger fixedly connected to a closure member, a valve housing, a valve seat, an electric motor configured to move the valve plunger, and a worm gear has an outer thread and an inner thread. The valve plunger has, at least in a sub-region, an outer thread and the valve arrangement has a threaded sleeve with an inner thread or a spindle nut with an inner thread, or the valve plunger is fixedly connected to a component having an inner thread and the valve arrangement has an outer thread. The valve plunger is connected to a first gearwheel, and the valve arrangement has at least one second gearwheel. The second gearwheel is arranged such that it can transmit a rotational movement directly, or via an intermediate gearing, to the first gearwheel.

Abstract: A valve for opening up or closing off a flow path includes: a valve disk; a valve tappet having: a central axis, a first end region adjacent to the valve disk, and a second end region facing away from the valve disk; and a transmission device configured to transmit a rotational movement into a translational movement. The transmission device includes: a toothed segment, and a rocker lever mounted so as to be rotatable, about a rocker lever axis of rotation, by a drive plate via the toothed segment. The rocker lever is connected to the valve tappet by pushrods, the pushrods being mounted rotatably in relation to the rocker lever and the valve tappet.

Abstract: The invention relates to a valve for opening and closing a flow path, comprising a drive motor, comprising a valve disk, comprising a valve tappet and comprising a transmission device for converting rotational movement of the drive motor into translatory movement of the valve disk, wherein the valve disk is connected to the valve tappet and is able to be moved by way of movement of the valve tappet, wherein the transmission device is formed from flexible elements and at least one toothed segment which is mounted so as to be rotatable about an axis of rotation, wherein only tensile forces are able to be transmitted by the flexible elements, and wherein the toothed segment is able to be at least partially wrapped around by the flexible elements by way of rotational movement.

Abstract: A valve for opening or closing a flow section has: a valve disk, a valve plunger and a transmission for converting rotary motion into translational motion. The transmission has a rocker arm mounted to rotate about an axis of relation, the rocker arm is linked to the valve plunger by connecting rods, and the connecting rods are mounted to rotate relative to the rocker arm and the valve plunger. A restoring device generates a force component to counteract a movement of the valve plunger transmitted to the valve plunger by the rocker arm and the connecting rods.

Abstract: A linear actuator for driving an actuating member of an internal combustion engine of a motor vehicle, the linear actuator having two rolling bearings for scanning mutually opposing sides of a rib that is formed as a guide curve. The rib has a variable width, against which the two sensing bodies are biased to reduce or eliminate undesired reaction forces.

Abstract: A linear actuator for driving an actuating element of an internal combustion engine of a motor vehicle has two scanning elements for scanning opposite sides of a guide cam. The guide cam has a protruding rib against which the two scanning elements are pre-tensioned to permit a play-free scan of the guide cam.
