Method and device for controlling at least one valve
First Claim
1. A method of controlling at least one valve, the valve being actuated by an activation signal, which represents the current through the valve coil, it being determined whether a leak, which may be related to a malfunction of the valve, arises in the control system which includes the at least one valve, wherein, in response to a detected leak, an activation signal of selected length and/or intensity and/or rate of change is output to activate the valve, thereby briefly opening the at least one valve and closing it again, or moving the valve ball onto the valve seat.

12. A device for controlling at least one valve, comprising a control unit, which includes at least one computer element, which produces an activation signal, for actuating the at least one valve, the computer element including means which detect a leak which may be related to a malfunction of the valve in the system that includes the valve, wherein the computer unit also includes means which, in response to a detected leak, operate the valve, using an activation signal of a selected length and/or intensity and/or rate of change, so that the valve opens briefly and closes again or the valve ball moves onto the valve seat.
