Abstract: A device for the actuation of a gas shuttle valve in an internal combustion engine that allows an optimization of both engine performance and fuel consumption by providing a variable valve lift. The lift of the gas shuttle valve can be varied by adjusting the effective axial distance of the actuators. As needed, the valve lift is increased or decreased in order to either improve engine performance or fuel consumption.

Abstract: A valve having a sleeve-like screening element for protecting an internal combustion engine against deposits in a region extending up from a hollow throat to a stripping edge. The screening element has a separate contactor guide surface for the combustion air supplied to the combustion chamber whose surface temperature is lower than the critical temperature for deposits at which fuel particles coke.

Abstract: A device for rotating a valve for producing rotations of a gas charging valve in an internal combustion engine during its opening and closing movements. The device has a basic body having a plurality of pockets oriented in a peripheral direction for receiving rolling bodies. There is also a valve shaft disposed in the basic body. In addition, there is also a plurality of rolling bodies and a plurality of tangential springs for holding the plurality of rolling bodies adjacent to the plurality of pockets on the basic body. Finally, there is a cover serving as a valve spring support and force transmitter or energy reservoir for each of the valve rotations, wherein the basic body and the cover consist of reshaped metal components. This design allows for a simple construction process resulting in lower manufacture costs.
