Embodiment Construction

[0050] figure 1 Examples of actuators for emergency opening of aircraft doors Co are shown, including:

[0051] - a cylinder 1 adapted to be connected at one of its ends 3 to a door Co and at its other end 4 to a reference frame Re of an aircraft (not shown) (the door is connected to said a frame of reference Re), such as the structure of an aircraft or any other intermediate connecting member between the door Co and said structure, said connecting member being movable during opening or closing of the door,

[0052] - fluid means 2, such as pressurized gas, for supplying the cylinder 1 for emergency opening of the hatch Co,

[0053] - means 5 for injecting a fluid measure 2 at a first point 19 of the first fluid passage 6, supplying the cylinder 1 for emergency opening of the hatch Co, the injecting means 5 can assume at least the following two positions:

[0054] - a first position, called the rest position, in which the fluid means 2 is isolated from the cylinder 1, as F...

Abstract

An aircraft hatch emergency opening actuator includes a cylinder connected to the hatch at one of its ends and at its other end to a reference frame of the aircraft. Fluid is fed to the cylinder for emergency opening of the hatch by a device able to adopt two positions. In a rest position the fluid is isolated from the cylinder, and in an active position the fluid is injected into a fluid circuit. A device for delaying the injection of the fluid into the cylinder includes a mobile element in the fluid circuit delaying opening of the circuit when the injection device is in the active position, the injection delay being determined by a time of movement of the mobile element.

Description

technical field [0001] The aircraft cabin door emergency opening actuator related to the present invention includes: [0002] - a cylinder arranged to be connected at its one end to said door and at its other end to a reference frame of the aircraft to which said door is connected, [0003] - fluid means for supplying said cylinder for emergency opening of said hatch, [0004] - injection means 5 for the injection of said fluid means at a first point of a first fluid channel supplying said cylinder for emergency opening of the hatch, said injection means being able to employ two Location: [0005] - a first position, called the idle position, in which said fluid means is isolated from said cylinder, and [0006] - a second position, called active position, in which said fluid measure is injected at said first point of said first fluid passage. Background technique [0007] Actuators of this type are known, for example actuators supplied by a reservoir of pressurized gas ...
