Abstract
A method for actuating a solenoid valve, which is used for throughflow rate control, of an agricultural spreading machine, wherein the solenoid valve has a valve armature, comprising: energizing the solenoid valve in order to cause an opening movement of the valve armature and/or in order to hold the valve armature in an open position in which the solenoid valve is open, interrupting or changing the energization of the solenoid valve in order to cause a closing movement of the valve armature in the direction of a valve seat, and causing a reduction in the movement speed of the valve armature during the closing movement of the valve armature.
Claims15
A method for actuating a solenoid valve of an agricultural spreading machine which is used for throughflow rate control, wherein the solenoid valve has a valve armature, comprising:
- energizing the solenoid valve in order to cause an opening movement of the valve armature or hold the valve armature in an open position in which the solenoid valve is open;
- and
- Interrupting or changing the energization of the solenoid valve in order to cause a closing movement of the valve armature in the direction of a valve seat;
- characterized by the step:
- causing a reduction in the movement speed of the valve armature (24) during the closing movement of the valve armature.
A system for actuating a solenoid valve of an agricultural spreading machine used for throughflow rate control, comprising
- a solenoid valve having a movable valve armature, and
- a control unit via which the solenoid valve can be energized to cause an opening movement of the valve armature and/or to hold the valve armature in an open position in which the solenoid valve is open;
- wherein the control unit is adapted to cause the energization of the solenoid valve to be interrupted or changed to cause a closing movement of the valve armature in the direction of a valve seat;
- characterized in that the control unit is adapted to cause a reduction in the movement speed of the valve armature during the closing movement of the valve armature by a control intervention, in particular by causing the solenoid valve to be energized.
