These members may comprise either a gear (29) that can be selectively engaged in rotation with peripheral toothings (28) of the rings (10) when the rotating body (13) is stopped, to bring the rings (10) to a relative angular position to which the situation of balance of the rotating body (13) corresponds, or locking elements to be selectively engaged with peripheral notches in the rings (10) to retain the rings (10) one by one while the rotating body (13) is rotated relative to the rings (10) through such an angle that the angular balance position is achieved.

Abstract: An electromagnetically-actuated two-way two-position valve is normally closed and comprises an axially-mobile group (5) which has an upper end (5a) that faces a fixed group (6) and which is attracted thereby. An obturator (4) is intercepted and then drawn in an opening movement by the mobile group (5) when the mobile group (5) is at a short distance from an end of its run. A return spring (9), which displaced the obturator (4) towards a closed position when the fixed group is deactivated, is entirely located behind the upper end (5a) of he mobile group (5). An air gap (8) is comprised, in a radial direction, between a coil (7) for activating the fixed group (6) and the upper end (5a) of the mobile group (5). The valve is constructionally simple and economical and has a higher fatigue resistance than known valves.
