  • Electromechanical actuator device, in particular for the actuation of fluid valves
    Patent number: 8393595
    Abstract: The device (1) includes a housing (2) in which an electric motor (5) is secured, the shaft (6) of this motor being coupled to a rotary control member (11) having on one surface a cam profile (11c) cooperating with a coordinated profile (20d) of a controlled member (20) which may move in translation in the housing (2) such that when the motor (5) is actuated, the rotation of the rotary control member (11) is adapted to cause the controlled member (20) to move in translation into a first position remote from the control member (11) or to enable this controlled member (20) to move in translation into a second position close to the control member (11).

  • Valve control device
    Patent number: 7156369
    Abstract: The device (1) comprises a support structure (2) in which at least a first opening (8, 9) is defined, a shutter (13) which is mounted for piloting in that structure (2) and which is adapted to take up a least a first and a second angular position, in which it closes and opens at least partially the first opening (8, 9) of the structure (2), respectively, and an actuator device (25) which is capable of bringing about a controlled angular movement of the shutter (13) relative to the support structure (2).
