  • Control assembly of a solenoid valve, solenoid valve assembly and associated methods
    Patent number: 11470997
    Abstract: A control assembly of a solenoid valve for a delivery device; the control assembly comprising a first input configured to be coupled to a control device of the delivery device and to be supplied by a power supply voltage from the control device; a first output configured to be coupled to a second input of a solenoid valve; a control unit being coupled to the first input; and a drive unit coupled to the first output and to the control unit; the control unit being configured to detect a first voltage at the first input; the control unit being configured to control the drive unit so that, when the control unit detects a first voltage equal to a power supply voltage, the first output of the control assembly delivers: a rated voltage for a first period of time, and a hold voltage different from the rated voltage for a second period of time following the first period of time, and wherein the hold voltage is lower than the rated voltage.
