ABSTRACT:
The method provides for applying to the solenoid valve, during its movement of closure by the action of a spring, a voltage signal the purpose of which is to brake this closure movement. The circuit comprises a static switch connected between the coil of the solenoid valve and earth, and an intermediate tap between these two components from which a voltage signal is withdrawn and is transformed by a microcontroller into a control signal for the static switch, such as to apply the braking signal to the solenoid valve.
