Abstract:
An electrical driver circuit for a cantilever solenoid valve, comprising:a first electrical switching device for converting a first logical control input signal into a first valve control output; a second electrical switching device for converting a second logical control input signal into a second valve control output; third and fourth electrical switching devices controlled as a function of the first valve control output produced by the first switching device; and fifth and sixth electrical switching devices controlled as a function of the second valve control output produced by the second switching device, a voltage potential difference being 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, such that either of said first or second electrically common points may have a higher voltage potential compared to the other of said first or second electrically common points, or both the first and second electrically common points may have the same voltage potential, as a function of the logical control input signals.
