    Abstract: A method for operating a fuel system for an internal combustion engine having a metering device, an electrical actuating device, and a valve element includes: activating the electrical actuating device in at least one first cycle in such a way that the valve element switches into a second position corresponding to an open metering device; activating the electrical actuating device in at least one second cycle in such a way that the electrical actuating device is activated from activation to activation, with activation energy which decreases gradually, until a limiting case is reached in which the valve element only just or just no longer switches into the second position; ascertaining a first activation energy, which corresponds to the limiting case; and subsequently activating the actuating device, taking the first activation energy into account.

    Abstract: In a method for actuating a switch element of a valve device between a first end position and a second end position, in a normal mode within a cycle following an end of a first energization, a movement of the switch element in a first direction effected by the loading device is retarded in a first direction by a brief second energization (“braking pulse”) that is introduced within the cycle once a pause period has ended following a characteristic point in time. It is provided that the optimum pause period and/or the optimum variable characterizing the braking pulse be ascertained in an adaptation mode.
