description In a fuel injector for an internal combustion engine comprising an injector housing including a valve element as well as a number of piezo-crystals stacked on top of one another for actuating the valve element, wherein the stack of piezo-crystals is supported by a carrier element which is disposed in a cavity of the injector housing in spaced relationship therefrom, a first seal is provided in a gap between the housing and the carrier element to close a fuel space in a sealed fashion and a further sealing element is located at a distance from the first seal in the gap so that a cavity is formed between the first seal and the sealing element for collecting fuel possibly leaking through the first seal.
