  • Method for actuating an electromagnetic valve, and corresponding fluid system
    Patent number: 10593458
    Abstract: A method for actuating an electromagnetic valve in a fluid system includes, for a specified first time period, a switching current with a specified first amplitude is applied, the switching current switching the electromagnetic valve from a rest state into a switching state. After the specified first time period expires, a holding current with a specified second amplitude is applied, the holding current holding the electromagnetic valve in the switching state. The first amplitude of the first switching current is greater than the second amplitude of the holding current.

  • MAGNET VALVE, AND DRIVER ASSISTANCE DEVICE COMPRISING SUCH A MAGNET VALVE
    Publication number: 20130306891
    Abstract: A magnet valve includes a magnet armature connected to a sealing element and configured to displace the sealing element. The magnet armature has faces. The magnet valve also includes fluid chambers and a flow path via which fluid chambers that lie on opposing faces of the magnet armature are fluidically connected. A damping element is arranged in the magnet valve and is configured to be displaced in an axial direction. The damping element protrudes into the flow path at least in some regions.

  • Method for reliably closing a solenoid valve
    Patent number: 8424978
    Abstract: A method is for closing a solenoid valve in which the solenoid valve is charged with a first current value that results in a first closing of the solenoid valve, and the solenoid valve is subsequently charged with a second current value that results in a renewed partial opening of the solenoid valve, and the solenoid valve is subsequently charged with a third current value that results in a second closing of the solenoid valve, the third current value being selected such that the second closing takes place with a higher closing speed of the solenoid valve than does the first closing.
