Thin Foil Encapsulated Assemblies
An injector tube assembly that includes thin foil insulation around a receiver tube and a relatively rigid housing secured to the thin foil and bearing on tube insulation while also being packed with junction insulation.
1 . A tube junction housing comprising:
a receptacle portion defining an insulation space;
a receptacle portion lip joined to the injector housing and defining an injector flange opening; and
a base flange joined to the a receptacle portion and including a thin-walled connection surface.
2 . The tube junction housing of claim 1 , wherein the
receptacle housing portion defines an injector tube axis through the injector flange opening and the base flange is substantially arcuate to define a receiver tube axis spaced apart from the base flange.
3 . The tube junction housing of claim 2 , wherein the injector tube axis and the receiver tube are disposed to define an angle of less than 90°.
4 . The tube junction housing of claim 1 , wherein the receptacle portion lip defines connector openings.
5 . The tube junction housing of claim 1 , wherein the base flange extends outwardly from the receptacle portion.
6 . The tube junction housing of claim 1 , and further comprising:
an injector flange disposed in the tube junction housing adjacent to and substantially co-planar with the injector flange opening.
7 . The tube junction housing of claim 1 , and further comprising:
insulation disposed in the insulation space.
8 . A tube junction assembly comprising:
a receiver tube defining a receiver tube axis;
tube insulation substantially surrounding the receiver tube; and
a thin foil spaced apart from the receiver tube and substantially surrounding the tube insulation;
an injector tube joined to the receiver tube at a tube junction and defining an injector tube axis; and
a tube junction housing having;
a receptacle portion defining an insulation space, and an injector opening, and a base flange joined to the receptacle portion and including a thin foil connection surface joined to the thin foil, and the base flange rests on the tube insulation and is spaced apart from the receiver tube.
9 . The tube junction assembly of claim 8 , wherein the base flange is substantially arcuate relative to, and spaced apart from, the receiver tube axis.
10 . The tube junction assembly of claim 9 , wherein the injector tube axis and the receiver tube axis are disposed to define an angle of less than 90°.
11 . The tube junction assembly of claim 8 , wherein the receptacle portion lip defines connector openings.
12 . The tube junction assembly of claim 8 , wherein the base flange extends outwardly from the receptacle portion.
13 . The tube junction assembly of claim 8 , and further comprising:
an injector flange disposed in the receptacle portion adjacent to and substantially co-planar with the injector flange opening.
14 . The tube junction assembly of claim 8 , and further comprising:
junction insulation disposed in the insulation space.
