Abstract
Abstract A gas-driven motor has a cylindrical rotor provided with helical vanes. The rotor has end bearings which are lubricated and cooled by spent gas passing out of opposite ends of the rotor. Pressurized gas is fed to a stationary cylindrical housing in which the rotor is mounted. In the housing the gas is distributed circumferentially around the rotor by a cylindrical manifold.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
167 words
A gas turbine motor comprising a generally cylindrical stator housing open at opposite ends, means for supplying pressurized gas to the housing at a point midway between opposite ends thereof, a cylindrical manifold centered between opposite ends of the housing to receive gas supplied thereto and to distribute the gas circumferentially around inside the housing, a rotor comprising a generally cylindrical member rotatably disposed inside the housing and arranged to receive gas leaving the manifold and impinging on the rotor to turn the same, a shaft extending axially of the rotor for engagement by a driven load and bearing means at opposite ends of said cylindrical member arranged to be cooled and lubricated by spent gas passing out of opposite ends of the housing, said cylindrical member has a central annular, circumferential flange, and sets of helical vanes on opposite sides of said flange, said vanes being oppositely pitches to cooperate in turning the rotor when said gas impinges thereon while inhibiting axial vibration of the rotor.
Claim 2
Dependent Claim
167 words
A gas turbine motor comprising a generally cylindrical stator housing open at opposite ends, means for supplying pressurized gas to the housing at a point midway between opposite ends thereof, a cylindrical manifold centered between opposite ends of the housing to receive gas supplied thereto and to distribute the gas circumferentially around inside the housing, a rotor comprising a generally cylindrical member rotatably disposed inside the housing and arranged to receive gas leaving the manifold and impinging on the rotor to turn the same, a shaft extending axially of the rotor for engagement by a driven load and bearing means at opposite ends of said cylindrical member arranged to be cooled and lubricated by spent gas passing out of opposite ends of the housing, said cylindrical member has a central annular, circumferential flange, and sets of helical vanes on opposite sides of said flange, said vanes being oppositely pitches to cooperate in turning the rotor when said gas impinges thereon while inhibiting axial vibration of the rotor.
Claim 3
Dependent Claim
24 words
A gas turbine motor as defined in claim 1, wherein said bearing means are ball bearings contained in bearing races engaged on said shaft.
Claim 4
Dependent Claim
61 words
A gas turbine motor as defined in claim 1, wherein said bearing means comprise floating members on ends of the rotor which is rotatively supported by said gas, said floating members cooperatively serving as valves for the supportive gas, said floating members being displaced oppositely by the gas flow as the rotor rotates to stabilize the rotor and minimize axial vibration.
Claim 5
Dependent Claim
43 words
A gas turbine motor as defined in claim 1, wherein the clindrical manifold has a cylindrical recess formed in said housing and oblique holes communicating between said recess and the interior of the housing to direct gas at oblique angles against said vanes.
Claim 6
Dependent Claim
23 words
A gas turbine motor as defined in claim 4, wherein said bearing means are ball bearings at opposite ends of the cylindrical member.
Claim 7
Dependent Claim
35 words
A gas turbine motor as defined in claim 5, wherein said housing has radial holes near opposite ends to pass excess gas out of the housing after the same has cooled and lubricated said bearings.
