Abstract
The electromagnetic valve comprises a movable core (8) adapted to be drawn toward a fixed core (7) under the influence of a magnetic field of an excitation winding (5). The lower portion of the core (8) has a skirt (11) surrounding a cylindrical member (9) which is shaped such that the fluid moving from passage (2) to passage (3) will be directed radially relative to the skirt (11), so as to avoid the exertion of a force on the core (8) in its direction of movement.
