Abstract: An aircraft door actuator, including: a pneumatic cylinder for the opening of the door including a chamber into which a pressurized gas is injected via a first port, means for supplying the chamber of the cylinder with pressurized gas, via a supply pipe and said first port, means for setting the chamber to atmospheric pressure when the piston is in the position for opening the door, so as to allow said door to be moved into the closing position, including: a pressurized gas exhaust pipe a gate-valve means for guiding the opening of the gate-valve via the pressurized fluid located in the chamber when the door is in the opening position, so as to open the exhaust pipe in order to set said chamber of the cylinder to atmospheric pressure in a rapid manner once the door is open.

Abstract: An aircraft hatch emergency opening actuator, includes, a cylinder connected to the hatch at one end to a reference frame at the other end to which the hatch is connected, fluid means feeding the cylinder for emergency opening of the hatch, means for injection of the fluid means at a point of a fluid circuit feeding the cylinder for emergency opening of the hatch, said injection means configured to adopt: a rest position, in which the fluid means are isolated from the cylinder, and an active position, in which the fluid means are injected at the point of the fluid circuit, means for delaying the injection of the fluid means into the cylinder including a mobile element in the fluid circuit, delaying opening of the circuit when the injection means are in the active position, the injection delay being determined by a time of movement of the mobile element.

Abstract: The present invention relates to devices for damping the movement of a body Co between two positions at the end of travel. The device according to the invention is essentially characterized in that it comprises two abutments B1, B2, a cylinder 10, a wall 11 closing off the end 12 of the cylinder 10, a piston 14 delimiting a chamber 16 with variable volume, a cylinder 20 with an external section at most equal to the internal section of the cylinder 10, a mounting unit for mounting the cylinder 20 in cooperation with the piston 14 so that the latter closes off the end 21 of this cylinder 20, a piston 24 delimiting a chamber 26 with variable volume, a first fluid Li filling the two chambers 16, 26, a communicating unit 30 for communication under pressure loss between the chambers 16, 26, an abutment 40 mounted in cooperation with the piston 24 so that this abutment 40 has a movement correlative with that of the piston 24, and a connecting unit 50 for connecting the cylinder 20 to the body Co.
