Abstract: A device and a method for cleaning a hydraulic control circuit such as the hydraulic circuit serving to control a hydraulic element, for example, a cylinder/damper assembly used for controlling the angle of an aircraft landing gear assembly and providing shock absorption on landing. The device comprises a cleaning circuit comprising a filter that is connected to the control circuit instead of the controlled element.

Abstract: A method and a tool for remotely pivoting an element mounted in a structure is provided. The method includes exerting a lever effect on the element by way of a control bearing on the structure coupled to a connection engaged with the element to cause it to pivot in a pivoting plane. The method also includes applying an angular offset to this connection in a plane different from the pivoting plane, in which the lever effect is produced, in order to render the control remotely operable.

Abstract: A secure corset is applied in particular to the immobilization in the maximum opening position of an aircraft landing gear cage hatch. The corset has two half-shells that are able to enclose the piston of the actuator having an axis coincident with the common longitudinal axis of the half-shells once they are closed around the piston. Locking pins are able to hold the half-shells around the actuator. The corset also has a casing secured to at least one of the half-shells and equipped with a hooking unit that is able to be coupled to a fixed point on the structure. A structure for varying the distance between the casing and the hooking unit are able to move the hooking unit away from or towards the corset along the common longitudinal axis of the half-shells.

Abstract: A bleeding system includes an open conduit and, upstream, a control controlling the hydraulic fluid flow, toward the open conduit. The bleeding system includes a dismountable connection device including connection mechanism adapted to be connected to the bleeding system; an outlet adapted to be connected to a pipe; a first central portion including the connection mechanism, a cylindrical bearing, and a conduit extending from the connection mechanism up to the surface of the cylindrical bearing; and an annular second portion including a bore adapted to pivot on the cylindrical bearing, at least one conduit connecting the outlet and the surface of the bore. The first portion and/or the annular portion include a groove ensuring the hydraulic fluid flows between the conduits. The central portion includes a section arranged between the connection mechanism and the cylindrical bearing to ensure the connection of the connection device to the bleeding system.

Abstract: A tool for holding the wheel bearing or the wheel bearing seal of a vehicle wheel. This tool is useful in the fields of aircraft manufacture and aircraft maintenance. The aircraft wheel is of the kind comprising a rim that has a flange on the hub side and a wheel bearing, mounted on a stub axle. The holding tool comprises a plate bearing a collar that presses against the wheel bearing. An arrangement to lock the tooling onto the rim of the wheel flange brings the pressing collar into locked contact with the wheel bearing.
