Abstract
Abstract A pressurized fluid engine comprising a rotor rotatable about a central axis of rotation and within a casing, the rotor having a hollow interior bounded on substantially its entire inner periphery by at least one inclined surface substantially parallel to and facing the axis having a leading end with respect to the direction of rotation closer to the axis than its trailing end in order that outward fluid pressure on the surface or surfaces exerts a mechanical leverage inducing the rotation. The fluid on the interior of the rotor after applying this pressure on the inclined surfaces escapes freely through an exit that is substantially free of any fluid compressing flow restrictions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
180 words
A pressure fluid engine comprising a rotor rotatable about a central axis, said rotor being hollow and bounded by a front and rear wall with a peripherally circular wall therebetween, said rotor having a central opening in one of said front and rear walls, said rotor having a smooth vaneless inner chamber portion adjacent said central opening and an outer vaned impElling portion, each of said vanes being of airfoil section having a substantially rounded leading edge, and an inner surface spiraling smoothly, arcuately outwardly and terminating in a trailing end lying in said peripheral circular wall, said adjacent vanes having cooperating relation and defining tangential substantially unrestricted discharge nozzles therebetween, each of said vanes extending substantially 180* about the axis of said rotor and projecting means defining a smooth outwardly extending flow surface from said other of said walls toward said central opening whereby fluid flow into the hollow rotor from said central opening is turned smoothly from an axial direction to radial in said vaneless portion of the rotor to enter said vaned portion with a radial component.
Claim 2
Dependent Claim
180 words
A pressure fluid engine comprising a rotor rotatable about a central axis, said rotor being hollow and bounded by a front and rear wall with a peripherally circular wall therebetween, said rotor having a central opening in one of said front and rear walls, said rotor having a smooth vaneless inner chamber portion adjacent said central opening and an outer vaned impElling portion, each of said vanes being of airfoil section having a substantially rounded leading edge, and an inner surface spiraling smoothly, arcuately outwardly and terminating in a trailing end lying in said peripheral circular wall, said adjacent vanes having cooperating relation and defining tangential substantially unrestricted discharge nozzles therebetween, each of said vanes extending substantially 180* about the axis of said rotor and projecting means defining a smooth outwardly extending flow surface from said other of said walls toward said central opening whereby fluid flow into the hollow rotor from said central opening is turned smoothly from an axial direction to radial in said vaneless portion of the rotor to enter said vaned portion with a radial component.
Claim 3
Dependent Claim
185 words
A pressure fluid engine comprising a rotor comprising a unitary plastic construction rotatable about a central axis, said rotor being hollow and bounded by a front and rear wall with a peripherally circular wall therebetween, said rotor having a central opening in one of said front and rear walls, said rotor having a smooth vaneless inner chamber portion adjacent said central opening and an outer vaned impelling portion, each of said vanes being of airfoil section having a substantially rounded leading edge, and an inner surface spiraling smoothly, arcuately outwardly and terminating in a trailing end lying in said peripheral circular wall, said adjacent vanes having cooperating relation and defining tangential substantially unrestricted discharge nozzles therebetween, each of said vanes extending substantially 180* about the axis of said rotor and projecting means defining a smooth outwardly extending flow surface from said other of said walls toward said central opening whereby fluid flow into the hollow rotor from said central opening is turned smoothly from an axial direction to radial in said vaneless portion of the rotor to enter said vaned portion with a radial component.
Claim 4
Dependent Claim
