Abstract: A discharge valve for an aircraft includes a cylindrical body having an inlet and an outlet, a first valve, and a second valve arranged inside the body. The first and the second valves are rotatable around a first axle and a second axle, respectively, between a closed position and an open position. A mechanism for locking the second valve in the closed position includes a control lever arranged around a third axle, an interface arranged on the second valve, and a device for rotating the third axle. The control lever is rotatably movable around the third axle between an unlocking position, in which the interface is in abutment against the drive device, and a locking position, in which the interface is engaged in the drive device.

Abstract: A magnetic head for a magnetic detector for detecting metal particles in a hydraulic circuit includes an axial body internally including at least one magnet, at least a first electrode defining an air gap zone located in the magnetic field created by the magnet, such that the circuit creates a particle alignment zone in the air gap, and an electrical connector for electrically connecting the electrodes. The magnet can be a diametrically magnetized magnet.

Abstract: This magnetic head (11) for a magnetic detector for detecting metal particles in a hydraulic circuit comprises an axial body (14) internally comprising at least one magnet (15, 16), at least a first electrode (17, 18) defining an air gap (E) located in the magnetic field created by the magnet, such that the circuit creates a particle alignment zone in the air gap, and means for electrically connecting (C) the electrodes. The magnet is a diametrically magnetized magnet.

Abstract: The invention relates to a coupling collar (5) for sealingly coupling two pipes (2) comprising: a first shell (8) and a second shell (9), each having a first end (8a, 9a) and a second end (8b, 9b); a pipe-connection element (30, 31) in contact with one of the shells (8, 9) and comprising a first portion (30a, 31a) and a second portion (30b, 31b), electrically connected to the first portion (30b, 31b). The first shell (8) and/or the second shell (9) comprises a sheath-connection element (36, 37) comprising a contact tab (38, 39, 38a, 38b, 39a, 39b, 57, 58) extending into a space arranged between the first ends (8a, 9a) and/or the second ends of the first shell (8) and the second shell (9), when the coupling collar (5) is in closed position.
