  • Patent number: 5997327
    Abstract: The present invention relates to a power connection device (1) which includes, on the one hand, a female part (2) with a lyre-shaped profile contained within and secured by an insulating support (3), which assembly is fixed inside a panel and is only accessible from one side, and on the other hand, a male part (6) to be plugged into said female part through said accessible side. This device is remarkable in that, in order to transfer high-intensity currents, the female part is composed of a thick, rigid multiclip (2) into which the male part, composed of a single thick plate (6), is inserted during the connection, which female part has a clamping zone (P) and which male part has a thickness (W) such that the insertion force is between 1.5 and 5 daN and that the resultant of the contact resistances is less than 60 N.OMEGA..

  • Patent number: 4503670
    Abstract: The invention relates to a deceleration limiter for a turbine engine. Through a rotary cam and a compressed spring, the throttle lever acts on a regulator for the fuel injector, for instance on the beam of a tachometric scale. According to the invention, the piston of a hydraulic damper and a push rod are interposed between the spring and the periphery of the cam. The chamber is connected to a source of ambient fluid under pressure p, which also acts on the other side of, through a damper valve which enables only the fluid to penetrate into, and by a diaphragm. The invention applies particularly to turbojet regulators to limit the magnitude and speed of development of the system parameters controlling the operation of the turbine engine following an abrupt deceleration command initiated by the pilot.
