Abstract
A moving wall positive displacement turbine system, or moving wall engine, utilizes the relative rotation of a ring, a central body, and a housing with respect to each other to generate power, where the ring is concentrically positioned in a channel between the central body and the housing. The housing and central body remain stationary while the ring rotates within the channel. The channel has low friction walls on either side to reduce friction between rotating components. The ring has a series of vanes passing through it and pivotally attached on each side to the low friction walls in the housing to compress an air-fuel mixture prior to combustion. The system is able to compress and combust an air-fuel mixture to generate direct rotational energy.
Claims9
A moving wall positive displacement turbine system comprising:
- a housing and
- a central body positioned concentrically within the housing, wherein a channel is delineated between a first running surface of the housing and a second running surface of the central body, wherein the first running surface and the second running surface are each contoured according to a polygonal profile with a plurality of lobes;
- a first low friction wall being attached to the first running surface;
- a second low friction wall being attached to the second running surface;
- a ring positioned within the channel having a plurality of radial slots;
- a plurality of vanes slidingly attached within and passing through the plurality of radial slots, wherein the plurality of vanes is pivotally attached between the first low friction wall and the second low friction wall;
- wherein the first low friction wall, the second low friction wall, the ring and the vanes form spaces with variable geometry;
- and
- wherein the housing and the central body are rotationally coupled;
- and
- a plurality of fuel injection ports being configured to inject an air-fuel mixture into the spaces for combustion as the housing and central body and the ring experience rotation relative to each other.
