  • Electrical driver circuit for direct acting cantilever solenoid valve
    Patent number: 6392864
    Abstract: An electrical driver circuit for a cantilever solenoid valve includes first and second electrical switching devices for converting logical control input signals into respective control outputs. Third and fourth electrical switching devices are controlled as a function of the control output produced by the first switching device. Fifth and sixth electrical switching devices are controlled as a function of the control output produced by the second switching device. A voltage potential difference is created between a first electrically common point, defined between the third and fourth switching devices, and a second electrically common point, defined between the fifth and sixth switching devices, as a function of the logical signals received into the first and second switching devices.
