Electromagnetically-actuated two-way valve

aaaAn electromagnetically-actuated two-way two-position valve is normally closed and comprises an axially-mobile group which has an upper end that faces a fixed group and which is attracted thereby. An obturator is intercepted and then drawn in an opening movement by the mobile group when the mobile group is at a short distance from an end of its run. A return spring, which displaced the obturator towards a closed position when the fixed group is deactivated, is entirely located behind the upper end of he mobile group. An air gap is comprised, in a radial direction, between a coil for activating the fixed group and the upper end of the mobile group. The valve is constructionally simple and economical and has a higher fatigue resistance than known valves.
