ABSTRACT:
A valve includes an air inlet for air coming from a first part of an engine intake passage, which is positioned upstream of a throttle valve and an air outlet for air moving toward a second part of the intake passage which is positioned downstream of the throttle valve. A hollow tubular element is connected to the air inlet and has primary connecting orifices between the air inlet and the air outlet. A movable obturator is housed within the tubular element. A magnetic core and winding is energized by an electrical control unit to generate a magnetic field to move a conical edge of the obturator to selectively open the primary connecting orifices to obtain laminar air flow across the primary connecting orifices, with this laminar air flow being directly proportional to the air passage section provided by the opened primary connecting orifices.
