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.
