A valve is provided having a circuit that includes an electrical conductor with a temperature-dependent electrical resistance. The electrical conductor is connected in series to an electrical series resistor, which includes a parallel circuit of a non-reactive wire and an NTC resistor. The electrical conductor includes a coil wire wound into a magnetic coil that is operable to move an armature to open or close the valve. The effect of the operation of the valve itself on the magnetic force of the coil is minimized by arranging the NTC resistor to be thermally coupled with the coil wire.

Valve with temperature compensation

An arrangement that is as simple as possible and that has very few lines, has a valve with a base element having a regeneration nozzle in which a regeneration channel is formed, having an outflow nozzle in which an outflow channel is formed, and having a drive flow nozzle in which a Venturi tube is accommodated, whereby the regeneration channel, the outflow channel and the Venturi tube are flow-connected is characterized in that a closeable bypass channel is provided which opens up into the drive flow nozzle and which is configured there in such a way that a fluid that is flowing in through the regeneration channel can be discharged through the Venturi tube as well as through the bypass channel.
