The water injection device for a steam iron comprises a plunger which is capable of axial displacement over a predetermined range of travel within the orifice of a nozzle which is formed of elastic material and closely encircles the plunger. The nozzle orifice provides a communication between a water reservoir and a vaporization chamber. A longitudinal groove is formed along part of the length of the plunger. The range of travel of the plunger is such that the two ends of the groove are located on each side of the nozzle orifice in the injection position and are located on one side of the orifice in the closed position.
