Abstract:
The invention provides a control circuit arrangement for solenoid valves, which has a timer adapted to supply the solenoid valve with a higher attraction current during an adjustable time starting with the beginning of a switching signal for the solenoid valve. After the time interval a low hold current flows until the end of the switching signal. For this purpose there is a semiconductor switch adapted to switch the flow of current through the solenoid valve. A logic gate arrangement is connected with an input of the switch and the gate arrangement is supplied with the output signal of the timer arranged to be triggered by the switching signal and the output signal of an oscillation generator. This circuit arrangement makes is possible to reduce a higher attraction current to a lower hold current in a simple and cheap manner, there only being a small overall size and as significant advantages it is possible for the arrangement to be converted for complementary logic.
