Abstract
Abstract A fluid vortex amplifier has a pin disposed in the position of the eye of a fluid vortex at the oulet of the vortex chamber so that the pin stabilizes the eye of the vortex and reduces the noise otherwise generated.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
117 words
A fluid vortex amplifier comprised of a cylindrical chamber having an outlet port at one end and substantially coincident with the axis of said chamber, a fluid inlet port in a wall of said chamber, means to direct a main stream of fluid radially in said chamber relative to the axis of said chamber, and a nozzle structure adapted to direct a control fluid flow generally tangentially in said chamber for imparting a vortex to said main stream of fluid, characterized by a fixed pin-like member disposed in said chamber having its axis substantially parallel to the axis of said chamber and forming a pivot about which said vortex rotates, said pin-like member having an irregular surface.
Claim 2
Dependent Claim
117 words
A fluid vortex amplifier comprised of a cylindrical chamber having an outlet port at one end and substantially coincident with the axis of said chamber, a fluid inlet port in a wall of said chamber, means to direct a main stream of fluid radially in said chamber relative to the axis of said chamber, and a nozzle structure adapted to direct a control fluid flow generally tangentially in said chamber for imparting a vortex to said main stream of fluid, characterized by a fixed pin-like member disposed in said chamber having its axis substantially parallel to the axis of said chamber and forming a pivot about which said vortex rotates, said pin-like member having an irregular surface.
Claim 3
Dependent Claim
18 words
A fluid amplifier as defined in claim 1 further characterized by said pin-like member having a threaded surface.
Claim 4
Dependent Claim
61 words
A fluid amplifier as defined in claim 1 further characterized by said fluid inlet port located in a side wall of said chamber and adapted to direct a main stream of fluid radially into said chamber, and said nozzle structure adapted to direct a control stream of fluid into said main stream entering said inlet and generally tangential of said chamber.
Claim 5
Dependent Claim
20 words
A fluid amplifier as defined in claim 1 further characterized by said pin-like member being concentric with said outlet port.
Claim 6
Dependent Claim
20 words
A fluid amplifier as defined in claim 1 further characterized by said pin-like member being eccentric to said outlet port.
Claim 7
Dependent Claim
72 words
A fluid vortex amplifier as defined in claim 1 further characterized by said inlet port being located in the end wall of said chamber opposite the end having said outlet port, circular wall means in said chamber arranged to deflect fluid entering said chamber through said inlet radially of said chamber and said fixed pin-like member having an irregular surface located on said wall means and extending coaxially with an outlet port.
