A method of diagnosing a valve is described, which has an electrodynamic actuator, which includes a coil, a movable magnet arrangement for generating a magnetic field, and a movable control element which is coupled to the movably arranged magnet arrangement. At least one electrical variable of the electrodynamic actuator is measured. The electrical variable is evaluated with respect to a reference variable to determine at least one induction-dependent valve variable which is assigned to the motion profile of the electrodynamic actuator. A diagnosis module and a valve are furthermore described.

Method of diagnosing a valve, diagnosis module, and valve

A valve includes an electrodynamic actuator which has a magnet arrangement for generating a magnetic field and a control element movable relative to the magnet arrangement. The control element includes an energizable coil which is arranged in the magnetic field and is firmly coupled to a coil carrier. The control element is movable between at least two defined positions. There are provided permanent-magnetically interacting holding force which retain the control element in at least one of the defined positions, even when the coil is currentless.
