Abstract: A gas metering valve for an internal combustion engine. The gas metering valve includes a housing in which a gas chamber is formed, which includes an inlet opening and an outlet opening. A movable valve element is situated in the gas chamber, which is movable by an electrical actuator against the force of a return spring and which cooperates with a valve seat for opening and closing the inlet opening. A blocking valve is situated between the valve element and the outlet opening, which opens in the flow direction to the outlet opening and blocks in the opposite flow direction.

Abstract: A method and a control unit, using which the damping of one or more damping elements on a vehicle that is able to be propelled by the driver, particularly a bicycle, is able to be varied. The propelling power of the driver or his behavior during the operation of the vehicle is recorded, in order to control or regulate the damping of the damping element as a function thereof. This is achieved by the setting of the damping taking place as a function of a power variable, which represents the propelling power of the driver or his behavior.

Abstract: What is disclosed is a lifting magnet assembly for a servo valve or control valve comprising a proportional magnet which acts on a valve spool of the control valve or servo valve through a tappet. Between the spool and the proportional magnet a failsafe magnet is provided which is penetrated or encompassed by the tappet of the proportional magnet.
