Abstract
Device for controlling by means of a current program a plurality of solenoid valves operating independently. Each solenoid is provided with a current flow control circuit having two inputs. The first input receives a first control signal which determines the duration of each actuation of the corresponding solenoid valve. The second input receives a second control signal derived from the first signal and of lesser duration. The current flow control circuit then provides a pull current to actuate the solenoid in response to these input signals.
