A gas distribution assembly for providing gas to an actuator for opening an aircraft door and to an aircraft evacuation slide, the assembly comprising a single common gas supply and valve means for controlling distribution of gas from the common supply between the slide and the door actuator based on door opening position.

Gas supply assembly for aircraft door actuator and evacuation system

A device according to the present invention comprises:

Device for assisting the operation of an aircraft door

Door actuator comprising means for setting to atmospheric pressure in a rapid manner at the end of opening the door

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:

Aircraft hatch emergency opening actuator including opening delay means

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 B, B, a cylinder, a wallclosing off the endof the cylinder, a pistondelimiting a chamberwith variable volume, a cylinderwith an external section at most equal to the internal section of the cylinder, a mounting unit for mounting the cylinderin cooperation with the pistonso that the latter closes off the endof this cylinder, a pistondelimiting a chamberwith variable volume, a first fluid Li filling the two chambers, a communicating unitfor communication under pressure loss between the chambers, an abutmentmounted in cooperation with the pistonso that this abutmenthas a movement correlative with that of the piston, and a connecting unitfor connecting the cylinderto the body Co. Application notably to the control for opening and closing an aircraft door.
