Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
141 words
A combustion apparatus including, in combination: a hollow body defining a combustion chamber therein, said hollow body formed with an opening therein, and a housing disposed outwardly of said combustion chamber, said housing including a downstream wall formed with an outlet of generally circular flow area in the fluid flow communication with said hollow body Opening, an upstream wall facing said outlet, an involute outer wall extending between and joining said upstream and downstream walls so as to define a spin chamber internally of said housing and a generally tangential inlet to said spin chamber, an annular array of swirl vanes extending between said upstream and downstream walls around said outlet, and passage means in fluid flow connection with said tangential inlet for delivery of liquid fuel and air to said spin chamber at a point radially outwardly of said vanes.
Claim 2
Dependent Claim
141 words
A combustion apparatus including, in combination: a hollow body defining a combustion chamber therein, said hollow body formed with an opening therein, and a housing disposed outwardly of said combustion chamber, said housing including a downstream wall formed with an outlet of generally circular flow area in the fluid flow communication with said hollow body Opening, an upstream wall facing said outlet, an involute outer wall extending between and joining said upstream and downstream walls so as to define a spin chamber internally of said housing and a generally tangential inlet to said spin chamber, an annular array of swirl vanes extending between said upstream and downstream walls around said outlet, and passage means in fluid flow connection with said tangential inlet for delivery of liquid fuel and air to said spin chamber at a point radially outwardly of said vanes.
Claim 3
Dependent Claim
44 words
The apparatus of claim 14 further characterized in that said passage means is formed with an upstream facing inlet for receiving a generally axially directed flow of air and includes one side wall formed as a generally streamline continuation of said involute outer wall.
