Abstract
An electromagnetically actuatable valve is proposed, which serves in particular to inject into the intake tube a mixture-compressing internal combustion engines with externally-supplied ignition. The valve includes a flat armature which is firmly connected with a ball arranged to cooperate with a fixed valve seat. The flat armature is pivotably supported on its end remote from the valve seat on a spring tongue preferably embodied out of a remnant air disc. A tubular inflow stub is disposed concentrically to the valve axis, communicating on one end with a fuel distributor line and on the other end protruding as deeply as possible into the valve. A tubular outlet stub leading away from the valve seat is concentrically guided in the inlet stub, and arranged to have its end remote from the valve seat discharge into a fuel return flow line. As a result, a cooling of the valve and the return of heated fuel which contains vapor bubbles to its supply source is assured.
