  • Patent number: 10968840
    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.

  • Patent number: 9938893
    Abstract: An electromechanical actuator to operate a component in an internal combustion engine comprising an actuator body housing, on the inside, an actuator device, which controls the movement of the component so as to move it between a maximum opening position and a maximum closing position, and vice versa. The actuator device includes an electric motor and a gear drive that transmits the motion from the electric motor to the component. The electromechanical actuator is made of a first metal material and comprises a conditioning circuit comprising a pipe for the passage of a conditioning fluid, which is made of a second thermally conductive material. A method of manufacturing the electromagnetic actuator is also disclosed.

  • Patent number: 7815167
    Abstract: A valve for adjusting the air flow rate in an internal combustion engine; the valve presents: a valve body; a cylindrical tubular pipe obtained within the valve body and in which an air introduction channel is defined; a valve seat obtained along the air introduction channel of the tubular pipe; an actuation system; a shutter, mobile under the bias of the actuation system; and a connection flange, which is integral with a first end of the tubular pipe and presents a plurality of through holes which are crossed in use by corresponding fastening screws for rigidly fixing the valve body; the connection flange is provided with a lower plate and an upper plate, which are reciprocally parallel, facing and distanced and are arranged radially with respect to the cylindrical tubular pipe, and a number of ribs, which reciprocally connect the plates, are arranged perpendicularly to the plates, and are arranged axially with respect to the cylindrical tubular pipe.

  • Patent number: 7759930
    Abstract: An actuator having a fixed part, a movable part movable with respect to the fixed part in a travelling direction, and a non-contact position sensor connected to the movable part to read the position of the movable part. The position sensor has a reading device connected to the fixed part and having a ferromagnetic core; and a magnetic cursor, which is integrated in the movable part, is defined by a magnetized portion of the movable part, and is so magnetized as to locally saturate the ferromagnetic core at the magnetic cursor.
