Abstract
The invention relates to an electromagnetically actuatable valve, which serves in particular to inject fuel into the intake 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 member which cooperates with a fixed valve seat and embodied as a ball element. The flat armature is pivotably supported on its side remote from the valve seat or on the side oriented toward the valve seat on a spring tongue preferably embodied out of a remnant air disc. The one-sided fixation of the flat armature on the spring tongue assures an unequivocal up-or-down movement of the flat armature.
Claims7
An electromagnetically actuatable valve for fuel injection systems of internal combustion engines, including a housing, a magnetic element in said housing, a flat armature positioned relative to said magnetic element for operation by said magnetic element, said flat armature having a side, a movable valve element and a fixed valve seat in said housing, said armature being firmly connected with said movable valve element which in turn cooperates with said fixed valve seat in said housing, a remnant air disc of nonmagnetic material fixed in said housing along an edge of said disc and disposed between said flat armature and said magnetic element, said remnant air disc including recesses therein and a portion extending between said recesses therein that form a spring element, said spring element being fixedly attached to said side of said flat armature at only one location, said spring element being attached to said flat armature to provide a pivotal movement for said armature about said one location, and a closing spring disposed between said armature and said magnet element which produces a force counter to said pivotal movement of said armature.
