  • Fluid flow control valve equipped with a conical flap and system comprising such valve
    Patent number: 11236831
    Abstract: A valve for controlling a fluid flow includes a valve body, a shutter component configured to be able to transition from an open position allowing the circulation of fluid, to a closed position preventing the circulation of fluid. The component is characterized in that it includes a fixed conical support integral with the valve body, a conjugate conical flap rotationally movable relative to the fixed support, and fluid passage apertures respectively arranged in the conical flap and in the fixed support, and an actuator of the shutter component adapted to be able to control the position of the shutter component.

  • Torque motor including a winding support for stator windings and method for assembling a torque motor of this type
    Patent number: 10897186
    Abstract: The invention relates to a torque motor comprising a stator and a rotor that extend along a common central axis. The stator includes an integral magnetic body and at least one pair of radial teeth that extend along the central axis and define slots for receiving stator windings, and at least one permanent magnet supported by the integral magnetic body. The torque motor also includes a winding support for the stator windings that has a hollow body that extends along the central axis and that delimits a chamber for receiving the rotor, and cavities for receiving the stator windings. In this way, the stator windings are integrated in the stator by the winding support, fitted with the stator windings, being axially inserted into the integral magnetic body.
