METHOD FOR CONTROLLING AN ELECTROMAGNETICALLY CONTROLLABLE GAS VALVE, AND CONTROL DEVICE

Abstract: a method for controlling an electromagnetically controllable gas valve. in order to open a seal seat, a solenoid coil acting on an armature is supplied with current so that a valve member interacting with the seal seat is lifted out of the seal seat by the armature and, in order to close the seal seat, the current supply to the solenoid coil is terminated so that the valve member is returned into the seal seat by the spring force of a closing spring, wherein the return of the valve member into the seal seat causes the armature to disengage from the valve member and perform a free stroke. a braking current is applied to the solenoid coil during the closing and, depending on the direction of movement of the armature, the current supply to the solenoid coil is interrupted and/or the current level is varied. a control device is also described.
