An electromagnetically controlled valve is described for controlling additional air flow delivered by feed equipment associated with an internal combustion engine. The feed equipment includes at least an engine intake passage and a throttle valve disposed in the passage. The electromagnetically controlled valve consists of: an air inlet for air coming from a first part of the intake passage, the air inlet being positioned upstream of the throttle valve: an air outlet for air moving toward a second part of the intake passage, the air outlet being positioned downstream of the throttle valve; a hollow tubular element connected to the air inlet and having primary connecting orifices between the air inlet and the air outlet; a movable obturator housed within the tubular element, the obturator comprising a bushing of non-magnetic material and a magnetic keeper housed within the bushing, the obturator being slidable within the tubular element; first and second stopping means for stopping movement of the obturator at limit positions within the tubular element; magnetic field generating means for generating a magnetic field to move the obturator between the limit positions, the generating means including a core disposed in a winding energizable by electrical control means.
