Abstract
An electromagnetic valve is provided with at least one coil containing at least one coil former. The coil former is provided with at least two separate wire windings, of which, in each case, two are connected in series or in parallel with one another.
Claims7
An electromagnetic valve, comprising:
- at least one coil containing at least one coil former;
- and
- at least two separate wire windings provided for the coil former, the two separate wire windings being operably configured to permit selective wiring in series or in parallel with one another during manufacture of the valve,
- wherein a number of wire windings and winding parameters of the wire windings are selected such that the coil supplies substantially identical electrical and magnetic characteristic variables when the wire windings are connected in series and a first voltage is applied and when the wire windings are connected in parallel and a second voltage is applied.

A method for producing an electromagnetic valve, the method comprising the acts of:
- providing at least one coil former of at least one electromagnetic coil with at least two separate wire windings;
- connecting, in each case, the two separate wire windings in series or in parallel with one another;
- arranging the connected wire windings of the at least one electromagnetic coil in a receptacle of the electromagnetic valve, and
- selecting a number of wire windings and winding parameters of the wire windings such that said coil supplies substantially identical electrical and magnetic characteristics variables when the wire windings are connected in series and a first voltage is applied and when the wire windings are connected in parallel and a second voltage is applied.
