Solenoid valve control circuit

Abstract

Title: Control circuit of a solenoid valve The invention relates to a control circuit (1) of a solenoid valve (200), in particular for being mounted on a motor vehicle, comprising: a line (30) to a first voltage source (31) capable of delivering a direct current voltage at a first voltage value (Up); a line (40) to a second voltage source (41) capable of delivering a direct current voltage at a second voltage value (Um), the first voltage value (Up) being greater than the second voltage value (Um); an inductor coil (2) configured to be connected: in a pull-in phase (PhA), to the first voltage source (31) in order to be able to move a plunger (201) of the solenoid valve (200) from a closed position to an open position of the solenoid valve (200);in a holding phase (PhM), to the second voltage source (41) in order to be able to hold the plunger (201) of the solenoid valve (200) in the open position of the solenoid valve (200).
