ABSTRACT:
A metering valve presenting a shutter for a discharge conduit, and an eleomagnet in turn presenting a fixed core and a disk-shaped armature detached from and sliding on the stem by means of a sleeve. The stem is guided by a bush, presents a flange movable inside a swirl chamber with a velocity damping effect, and is fitted, prior to assembling the armature and the electromagnet, by means of a ring nut, which presses a flange, forming one piece with the bush, against the body of the valve via the interposition of calibrated washers so selected as to define the travel of the stem.
