Claim 0:
1. A method for determining a switching state of an inlet valve that is actuated by a coil, wherein the method comprises:
respectively ascertaining a current flowing through the coil and a voltage applied to the coil at several times which follow one another with a prespecified time interval, calculating an inductance variable of the coil based on the currents, the voltage and the time interval,
determining the switching state based on the inductance variable, and
monitoring the switching state of the inlet valve by monitoring whether a tappet of the inlet valve falls back to a tappet starting position after the coil is switched off, and without a non-return valve.
