ABSTRACT:
Electrically operated valve for liquid or gaseous media, suitable for internal combustion engines, possessing an electrically-activated actuating element with a short actuating displacement, this actuating element acting on a control valve, and possessing a nozzle element which unblocks a nozzle when a defined pressure is present in the supply line. The actuating element is connected to an actuating-element base and is pressed, by means of an actuating-element spring, against the control-valve plate of the control valve, this control-valve plate being pressed, by a stronger control-valve spring, against a fixed reference plane. In order to compensate for changes in the length of the actuating element, resulting from mechanical forces and/or from temperature changes, a collect-type clamping device is provided, which is subjected to the pressure of the medium and clamps the actuating element while it is being operated.
