    摘要: A hydraulic valve (3, 3′) of a servo-control for feathering the blades (1) of a rotorcraft rotor. The hydraulic valve (3, 3′) comprises a main valve member (5) and an emergency valve member (6) blocked relative to a valve cylinder (4) of the hydraulic valve (3, 3′) by means of a pin (23) in sliding thrust engagement in a cavity (24) of the emergency valve member (6). Relative movement between the emergency valve member (6) and the valve cylinder (4) initiating sliding movement of the pin (23) inside the cavity (24) and causing mover means (27) for moving the pin (23) to be put into operation, thereby releasing the emergency valve member (6) to move freely.

    摘要: A servo-control having at least one movable cylinder that includes a hydraulic directional control valve. The hydraulic valve includes a control shaft that is rotatable about a longitudinal axis, the control shaft being connected to a distributor slide. The servo-control including a stationary abutment member secured to a cylinder and an input lever situated outside the cylinder. The input lever is connected to the control shaft and includes a stop portion arranged in the abutment member. The servo-control includes movement means for moving the input lever longitudinally, a first abutment surface of the abutment member limiting a travel amplitude of the stop portion when the input lever is in a first position.

    摘要: A pressure-balance valve for balancing the pressures of fluids admitted into the pressure-balance valve via respective second ducts. The pressure-balance valve has both a chamber for guiding movement in translation of a piston, and also fluid flow paths, each comprising a said second duct and a first duct for admitting a fluid coming from the same fluid source as the fluid flowing in its second duct. Each of the first ducts is provided with a shutter co-operating with a ramp arranged on the piston. Movement of the piston in translation as a result of a pressure difference between the fluids respectively admitted into the second ducts causes one of the shutters to slide along the corresponding ramp and consequently allows additional fluid to be delivered from a first duct to the second duct of the same fluid flow path.

    摘要: A lead-lag damper arranged inside a blade of a rotor of a rotary wing aircraft. The lead-lag damper (comprises an inner strength member provided with a cage in which a ball-joint connection is arranged, an outer strength member for securing to the blade, and an elastomer material member arranged between the two strength members. The two strength members and the elastomer material member extending beyond the zone around the cage so that the relative movements between two strength members resulting from the movements of the blade are damped by deformations of the elastomer material member, at least a portion of the lead-lag damper being designed to occupy a portion of the inside of the blade that is conventionally filled with foam.
