Abstract
The invention relates to an electromagnetically actuatable valve, which serves in particular to inject fuel into the suction tube of mixture-compressing internal combustion engines having externally supplied ignition. The valve includes a flat armature which is firmly connected with a movable valve element, embodied as a ball which cooperates with a fixed valve seat. The flat armature is provided on its side remote from the valve seat with recesses into which spring tongues formed from a remnant air disc protrude, resting under the influence of voltage on the flat armature and guiding it in parallel fashion.
Claims8
An electromagnetically actuatable fuel injection valve for fuel injection systems of internal combustion engines having a housing, a magnetic element in said housing, a flat armature positioned relative to said magnetic element for operation by said magnetic element, a movable valve element secured to said flat armature and arranged to cooperate with a fixed valve seat in said housing, characterized in that a remnant air disc of non-magnetic material is disposed within said housing between said flat armature and said magnetic element, said remnant air disc further including at least four spring tongues arranged to guide said flat armature and urge (it) said valve element in a closing direction of said valve seat.
