Bernhard Rust has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Hydraulically operated valve actuation and internal combustion engine with such a valve actuation
    Patent number: 8381693
    Abstract: According to the invention, recuperation may be optimized for a hydraulically-operated gas exchange valve by provision of two fluid-filled pressure chambers and a movable regulating piston with two active faces each defining one of the pressure chambers. The pressure chambers are each connected to two hydraulic valves of which the first hydraulic valves may be pressurized from a first pressure reservoir and the second hydraulic valves may be connected to a base pressure reservoir. The first hydraulic valves may furthermore be connected to a second pressure reservoir. A control or regulation device switches the valves, from a rest position in a first accelerating phase and a braking phase.

  • HYDRAULICALLY OPERATED VALVE ACTUATION AND INTERNAL COMBUSTION ENGINE WITH SUCH A VALVE ACTUATION
    Publication number: 20100307433
    Abstract: According to the invention, recuperation may be optimised for a hydraulically-operated gas exchange valve by provision of two fluid-filled pressure chambers and a movable regulating piston with two active faces each defining one of the pressure chambers. The pressure chambers are each connected to two hydraulic valves of which the first hydraulic valves may be pressurised from a first pressure reservoir and the second hydraulic valves may be connected to a base pressure reservoir. The first hydraulic valves may furthermore be connected to a second pressure reservoir. A control or regulation device switches the valves, from a rest position in a first accelerating phase and a braking phase.
