ABSTRACT:
The invention is based on an injection valve which serves in particular to supply fuel to internal combustion engines having fuel injection systems. The injection valve includes a movable valve element, which cooperates with a fixed valve seat provided on a nozzle body.
Additionally, the movable valve element and the fixed valve seat each have complementary formed confronting surfaces, at least one of these surfaces being provided with a support such as a rib, thereby maintaining these surfaces in space relation. The rib may be provided on either the movable valve element or the fixed valve seat and can comprise an annular configuration whereby a collection chamber is provided between the respective surfaces. The confronting surfaces may be either concave or convex.
