  • Patent number: 9709003
    Abstract: The invention relates to an actuator device (8) for moving a movable cowl of a thrust reverser, including: an actuator (12) including a screw (14) and a nut (15) capable of engaging with the screw (14) such that a rotation of the screw relative to the nut translates the nut relative to the screw; a locking device (30) including a locking part (31, 57) which is movable relative to the screw (14) between a locked position in which the locking part (31, 57) prevents the rotation of the screw (14) and an unlocked position in which the locking part (31, 57) allows the rotation of the screw (14), in which the screw (14) includes a body (17) and a lock-inhibiting device (38), the lock-inhibiting device (38) including an inhibiting part (47, 48) which is movable relative to the body (17) between a first position in which the part (47, 48) allows the locking part (31, 47) to move between the locked position and the unlocked position, and a second position in which the inhibiting part (47, 48) prevents the locking part

  • Patent number: 8829416
    Abstract: The invention relates to a passive mechanical athermalization device, comprising: a barrel (1) that is made of a first material having a first thermal expansion coefficient (11) and that has a longitudinal axis (AA), said barrel comprising at least one first portion (11) and at least one second portion (12), the device being characterized in that it comprises: at least three beams (7) made of the first material, each of the beams (7) circumferentially connecting the first portion (11) and the second portion (12) relative to the longitudinal axis (AA); at least three bars (8) made of a second material having a second thermal expansion coefficient (12) that is different from the first thermal expansion coefficient, circumferentially distributed around the barrel (1) relative to the longitudinal axis (AA), each bar (8) axially connecting the first portion (11) and the second portion (12) relative to the longitudinal axis (AA) such that the thermal expansion of the barrel (1) results in a deformation of the beams

  • Publication number: 20080079521
    Abstract: An electromagnetic actuator comprising an actuator member (7, 8) movable under the action of at least one electromagnet (1) comprising a coil (3) associated with a core (2) arranged to channel magnetic flux generated by the coil (3) so that it loops through the actuator member, the coil comprising a winding (21) of conductor wire covered in a casing (20), and the electromagnet including at least one permanent magnet (4) disposed relative to the core (2) in such a manner that the core channels flux generated by the permanent magnet so that it loops through the actuator member. According to the invention, the casing of the coil covers at least part of the permanent magnet (4) in such a manner as to secure the permanent magnet (4) to the winding (21) of conductor wire, such that the conductor wire winding and the permanent magnet form a one-piece unitary assembly suitable for being fitted on the core.

  • Patent number: 6651954
    Abstract: The electromagnetic valve actuator has an armature (22) of ferromagnetic material fixed to the stem of the valve, springs are provided to hold the valve at rest in a middle position between a fully open position and a closed position, and a single coil (38) is mounted on a ferromagnetic circuit. In combination with the armature, the magnetic circuit presents two stable magnetic flux paths both of which correspond to an airgap of small size.
