Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
90 words
An omnidirectional turbine, comprising: hub means for rotation about an axis; coupling means, engaged with said hub means, for transmitting rotary motion of said hub means to a point of utilization; and a plurality of deflector means, each having a configuration offering a maximum resistance to fluid flow from one direction while offering a relatively lesser resistance from any other direction, affixed to said hub means, for providing a net torque of a first sense to said hub in response to fluid flow in any direction relative to said turbine.
Claim 2
Dependent Claim
90 words
An omnidirectional turbine, comprising: hub means for rotation about an axis; coupling means, engaged with said hub means, for transmitting rotary motion of said hub means to a point of utilization; and a plurality of deflector means, each having a configuration offering a maximum resistance to fluid flow from one direction while offering a relatively lesser resistance from any other direction, affixed to said hub means, for providing a net torque of a first sense to said hub in response to fluid flow in any direction relative to said turbine.
Claim 3
Dependent Claim
18 words
The omnidirectional turbine of claim 1 wherein said plurality of deflector means comprises a plurality of hemispherical elements.
Claim 4
Dependent Claim
73 words
The omnidirectional turbine of claim 1 wherein said plurality of deflector means comprises eight deflector elements positioned at equal angles around the perimeter of said hub means, said deflector means for providing said torque of a first sense about said axis in response to fluid flow perpendicular to said axis with alternate elements responsive to fluid flow along said axis in opposite directions causing a torque about said axis of said first sense.
