Abstract (en)
A servo controlled valve (1) for adjusting the intake air flow rate in an internal combustion engine; the servo controlled valve (1) presents: a valve body (2), in which an air passage channel (3) is defined; an electrical motor (7) carried by the valve body (2); a valve seat (4) obtained within the valve body (2) and along the air passage channel (3); and a shutter (5) which engages the valve seat (4) and is rotationally mounted about an axis of rotation (6) perpendicular to the air passage channel (3) to turn between an opening position and a closing position of the air passage channel (3) under the bias of the electrical motor (7); the shutter (5) has a cylindrical shape, a longitudinal axis of symmetry coaxial to the axis of rotation (6), and presents an internal pipe (8) which is through and perpendicular to the axis of rotation (6) so as to be aligned with the air passage channel (3) in the opening position and to be perpendicular to the air passage channel (3) in the closing position.
