Abstract
An injection nozzle for injecting fuel into the combustion chamber of an air-compressing internal combustion engine is provided, having a valve closing member which lifts inwards from its valve seat as a function of the fuel pressure. The valve closing member is formed by a diaphragm which is firmly clamped in the nozzle body and lifts to a greater extent during the opening pressure of the injected fuel in the direction of the spray openings. A dilatant liquid or a non-dilatant liquid with a certain portion of gas is used as a closing spring for the diaphragm.
