ABSTRACT:
A valve for metering a fluid including a small upper plate, a small middle plate and a small lower plate. The small middle plate has a closing element with a diaphragm region surrounding the closing element. The stroke of the closing element is limited in an axial direction by the small upper plate and by a valve seat of the small lower plate. As a result, very accurate metering of the fluid is possible. The valve is especially suitable as an injection valve for injection systems of mixture-compressing internal combustion engines with externally supplied ignition.
