ABSTRACT:
The sealing element has a ring consisting of an elastic material. The ring consists of a continuous support section, a first sealing lip, formed thereon for sealing the injector casing and a second sealing lip for sealing the cylinder head. The sealing lips project substantially inwards in a radial direction and together with the support section form a continuous groove of the ring. An alignment member is at least partially positioned in the groove of the ring, the alignment member is configured such that when a valve stem portion of the injector casing is positioned through the ring, the alignment member physically contacts the valve stem portion at two or more distinct locations to fix the ring non-positively around the valve stem portion such that the ring is prevented from physically contacting the valve stem portion.
