Abstract: A throttle body or actuator for an engine, comprising a main body which defines at least one supply duct having a through lumen for a gas mixture, a choke valve placed inside said supply duct so as to modify said through lumen. The choke valve is provided with an occluding body connected to a control shaft, at least partially housed in a seat in the main body. The control shaft, inside the seat and on the side of the occluding body, is provided with a first gasket adapted to prevent the penetration of dirt and gas from the supply duct. Downstream of the first gasket, on the side of the control shaft, at least one vent is provided, adapted to allow the expulsion, outside the seat, of any gas which has leaked through the first gasket.

Abstract: A method to manufacture a throttle valve for an internal combustion engine comprising a valve body having a seat and a tube for the passage of conditioning fluid; an actuating device, which controls the rotation of a throttle plate; and a substantially uniform layer of a structural and heat-conducting resin interposed between the seat and the tube and applied on the entire available surface of the seat; the method comprising the steps of manufacturing the valve body provided with the seat by causing a first metal material to undergo a die casting process; applying a trace of the structural and thermosetting resin on the bottom of the seat; and inserting the tube into the seat so as to obtain a substantially uniform layer of the structural and thermosetting resin, which is interposed between the seat and the tube.

Abstract: An actuator comprising a main body which delimits a kinematic chamber inside which a valve and/or a relative drive mechanism of the valve is at least partially housed, a closing lid that can be associated to close the kinematic chamber of the main body, wherein the throttle body contains a position sensor, of the magnetic or magneto-resistive type, facing a slider of the valve and/or a component of the drive mechanism so as to read the position of the slider and therefore of the relative valve and/or of the relative component of the drive mechanism. Advantageously, the closing lid is provided with a screening device of electromagnetic fields for the position sensor and the slider, positioned near the position sensor, on the side opposite the kinematic chamber with respect to the position sensor.

Abstract: Actuator for automotive applications, comprising a main body that houses a motor, a transmission, a control shaft, kinematically connected to the motor by the transmission. The control shaft extends from a first transmission end, connected to the transmission, to a second operating end operatively connected to a user device. The control shaft is controlled in a reciprocating linear motion along an axial direction (Y-Y) by the transmission which transforms a rotation movement along a drive axis (X-X) of the motor into a translation movement of the control shaft along said axial direction (Y-Y). The motor and the control shaft are oriented so that the drive axis (X-X) and the axial direction (Y-Y) are perpendicular or parallel and spaced apart from each other.
