FLUID EJECTION DEVICE
The disclosed embodiments relate to a pressurised fluid ejection device. More especially, the disclosed embodiments relate to such a device especially intended for fire fighting with improved reliability and efficiency, especially concerning the device placing the tank in communication with the fluid distribution circuit, including: a tank containing fluid, a fluid ejection port, ejection port closing means, a device capable of opening the said closing means including a breakable seal and means capable of retaining the seal after breakage comprising a pivot with an axis perpendicular to the ejected fluid flow.
1 . Fluid ejection device characterised in that it includes:
a tank ( 1 ) containing the fluid ( 10 )
a fluid ejection port ( 2 )
closing means ( 3 ) for the ejection port including a breakable seal ( 3 , 3 a , 30 , 300 )
a device capable of causing the opening of the closing means ( 5 )
means ( 20 , 32 , 37 , 320 , 364 ) for retaining the broken section ( 31 , 301 b , 361 b ) of the seal after breakage forming a pivot with the said broken section, the axle of the said pivot being perpendicular to the ejection flow ( 11 ) of the fluid.
2 . Device according to claim 1 characterised in that the seal includes a weakened zone ( 31 , 7 , 301 a , 361 a ) capable of initiating the breakage of the said seal over at least a section of its periphery.
3 . Device according to claim 2 characterised in that the pivot consists of a deformable link ( 32 , 364 ).
4 . Device according to claim 3 characterised in that the pivot consists of an unweakened zone ( 32 ) of the seal.
5 . Device according to claim 3 characterised in that the axle of the pivot is off-centred in relation to the central axis of the fluid ejection port.
6 . Device according to claim 1 characterised in that the seal includes a weakened zone over its complete periphery ( 7 , 301 a , 361 a ).
7 . Device according to claim 6 characterised in that the fluid ejection port has a more or less rectangular section.
8 . Device according to claim 7 characterised in that the axle of the pivot is attached to the seal and that it includes sliding guide means ( 321 ) of the said axle in a plane parallel to the ejection flow ( 11 ).
9 . Device according to claim 8 characterised in that it includes sliding guide means ( 322 ) for the axle in an oblique plane with regard to the ejection flow.
10 . Device according to claim 8 characterised in that the broken section of the seal located in the ejection flow has a profile ( 304 ) capable of favouring its retraction by hydrodynamic effect.
11 . An aircraft characterised in that it includes a device according to claim 1 .
