Abstract: A torque meter includes a casing and a part is configured to move in the casing in translation in a longitudinal direction under the effect of an axial thrust representative of the torque to be measured. The torque meter further includes a bearing surface connected to the casing via at least one of the ends thereof. The bearing surface extends at least partially in a plane that is substantially perpendicular to the longitudinal direction. One longitudinal end of the movable part is configured to be brought into contact with the bearing surface so that a longitudinal displacement of the movable part leads to a deformation of the bearing surface. The torque meter also has a device configured to measure the deformation of the bearing surface.

Abstract: The invention relates to a mechanical fuse intended to be rigidly mounted between a drive unit (8, 9), and a receiver unit (10), each rotating about the same axis (7) of rotation, said fuse comprising a body (13) extending in a longitudinal direction parallel to said axis (7) of rotation, once the fuse is mounted between said drive unit (8, 9) and receiver unit (10). The invention is characterized in that said body (13) comprises a plurality of longitudinal bars (14), each bar (14) being deformable by bending, such as to form a twist-breakable mechanical fuse.

Abstract: A filler device for a fluid tank, including: a filler duct; a first stopper, for preventing overfilling of the tank, and a second stopper for preventing fluid from leaving the tank in unwanted manner; a first float mechanically connected to the first stopper such that, on being placed in a predetermined position, the first float closes the first stopper; and a holder system for holding the second stopper, which system, when fluid leaves the tank, closes the second stopper, and when fluid enters into the tank, opens the second stopper. In an operating position of the device, and under effect of a heavy element, the holder system acts continuously on the second stopper, tending to maintain the second stopper permanently in its closed position.
