Abstract
Abstract A fluid amplifier with a saturation characteristic, the amplifier consisting of a main fluid inlet conduit supplied with a fluid to be controlled, a plurality of fluid flow outlet conduits disposed downstream of the main fluid inlet conduit at a predetermined distance to receive the controlled flow from the main inlet conduit, a vortex chamber between the main fluid inlet conduit and the fluid flow outlet conduit for producing vortex flow, control fluid inlet nozzles directed into said vortex chamber in the same direction as the vortex flow and supplied with control flow fluid for acting on the vortex flow to control the deflection of the fluid from the main fluid inlet conduit, and airfoillike elements positioned within the vortex chamber in alignment with the fluid flow from the main inlet conduit for limiting the deflection of the fluid flow from the main fluid inlet conduit to maintain a saturated condition of deflected main fluid flow.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
168 words
A fluid amplifier comprising main fluid inlet means supplied with a fluid to be controlled, fluid flow outlet means disposed downstream of said main fluid inlet means at a predetermined distance therefrom to receive the controlled flow from said main fluid inlet means, enclosed vortex means between said main fluid inlet means and fluid flow outlet means for producing vortex flow, vent means spaced from the vortex means and extending into said outlet means, controlled fluid inlet means extending into said vortex means in the same direction as said vortex flow produced in said vortex means and supplied with controlled fluid acting on said vortex flow to control the deflection of the fluid flow from the main fluid inlet means, and airfoillike means positioned within said vortex means in alignment with the fluid flow from the main fluid inlet means for limiting the deflection of the fluid flow from said main fluid inlet means, whereby to maintain a saturated condition of deflection in the deflected main fluid flow.
Claim 2
Dependent Claim
168 words
A fluid amplifier comprising main fluid inlet means supplied with a fluid to be controlled, fluid flow outlet means disposed downstream of said main fluid inlet means at a predetermined distance therefrom to receive the controlled flow from said main fluid inlet means, enclosed vortex means between said main fluid inlet means and fluid flow outlet means for producing vortex flow, vent means spaced from the vortex means and extending into said outlet means, controlled fluid inlet means extending into said vortex means in the same direction as said vortex flow produced in said vortex means and supplied with controlled fluid acting on said vortex flow to control the deflection of the fluid flow from the main fluid inlet means, and airfoillike means positioned within said vortex means in alignment with the fluid flow from the main fluid inlet means for limiting the deflection of the fluid flow from said main fluid inlet means, whereby to maintain a saturated condition of deflection in the deflected main fluid flow.
Claim 3
Dependent Claim
202 words
A fluid amplifier comprising a main fluid inlet supplied with a fluid to be controlled, a pair of fluid flow outlets disposed downstream of said main fluid inlet at a predetermined distance to receive the controlled flow from said main fluid inlet, a pair of enclosed vortex chambers between said main fluid inlet and the fluid flow outlets arranged symmetrically with respect to the centerline passing though said main fluid inlet for producing a vortex flow in each of said vortex chambers, means defining a pair of vent passages spaced from the vortex chambers and extending into said respective outlets, a pair of control inlets extending respectively into said pair of vortex chambers in the same direction as said vortex flow produced in each of said vortex chambers and supplied respectively with control fluid acting on the vortex flows to control the deflection of the fluid flow from the main fluid inlet, and a pair of airfoillike members symmetrically positioned within said vortex chambers in alignment with said fluid flow from said main fluid inlet for limiting the deflection of the fluid flow from said main fluid inlet, whereby to maintain a saturated condition of deflection in the deflected main fluid flow.
