  • Patent number: 10900571
    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.

  • Patent number: 10634101
    Abstract: Exhaust gas recirculation valve actuator device in an internal combustion engine, comprising an actuator body housing where the stem of an exhaust gas recirculation valve, extends along an axial direction. A motor acts to move the recirculation valve along the axial direction X-X, to pass from an open configuration to a closed configuration. A transmission is interposed between the motor and the exhaust gas recirculation valve. The device also includes support and guide mechanism and a sealing mechanism, in correspondence of a connection interface of the actuator body with an associable valve body, which houses an exhaust gas passage duct, wherein the actuator body is mechanically separable/connectable from/to said associable valve body.

  • Publication number: 20200040990
    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.
