Abstract
Abstract An engine comprising a rotatable casing, a plurality of circumferentially disposed variable volume chambers in said casing, said chambers being serially interconnected and defining a plurality of stages in said engine, means for introducing a motive fluid to rotate said casing into the inner of said chambers, means to exhaust said motive fluid from the outer of said chambers, a plurality of vane holder shafts mounted in a support member disposed in said casing, each of said vane holder shafts having a vane disposed in each of said chambers, said vane holder shafts being rotatable about their axes and being nonrotatable about the axis of rotation of said casing, the sizes and configurations of said variable volume chambers and of said vanes being correlated so that upon rotation of said casing and rotation of said vane holder shafts about their axes the edges of said vanes are maintained in close proximity with the walls of said variable volume chambers, and power takeoff means operatively connected to said rotatable casing.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
182 words
An engine comprising a rotatable casing, said rotatable casing being provided with a plurality of variable volume chambers concentrically disposed with respect to each other about the axis of rotation of said casing, supply means to introduce a fluid into one of said variable volume chambers, passage means connecting said variable volume chambers to each other in series to enable fluid exhausted from one chamber to flow to the next, means to withdraw the fluid from the last of said variable volume chambers, a plurality of vane holder shafts disposed in said casing and mounted for rotation about their axes, a plurality of vanes disposed on each vane holder shaft with one vane being positioned in each variable volume chamber, said vane holder shafts being nonrotatable with respect to the axis of rotation of said casing, and means to rotate said vane holder shafts in correlation with rotation of said casing to maintain the edges of said vanes in close proximity to the surfaces of the respective variable volume chambers throughout rotation of said casing under the influence of said motive fluid.
Claim 2
Dependent Claim
182 words
An engine comprising a rotatable casing, said rotatable casing being provided with a plurality of variable volume chambers concentrically disposed with respect to each other about the axis of rotation of said casing, supply means to introduce a fluid into one of said variable volume chambers, passage means connecting said variable volume chambers to each other in series to enable fluid exhausted from one chamber to flow to the next, means to withdraw the fluid from the last of said variable volume chambers, a plurality of vane holder shafts disposed in said casing and mounted for rotation about their axes, a plurality of vanes disposed on each vane holder shaft with one vane being positioned in each variable volume chamber, said vane holder shafts being nonrotatable with respect to the axis of rotation of said casing, and means to rotate said vane holder shafts in correlation with rotation of said casing to maintain the edges of said vanes in close proximity to the surfaces of the respective variable volume chambers throughout rotation of said casing under the influence of said motive fluid.
Claim 3
Dependent Claim
24 words
An engine according to claim 1, wherein said variable volume chambers increase in overall volume progressively from the innermost chamber to the outermost chamber.
Claim 4
Dependent Claim
34 words
An engine according to claim 1, further comprising a stationary vane shaft support member disposed in said casing and having portions disposed on opposite sides of said vane holder shafts in close proximity thereto.
Claim 5
Dependent Claim
19 words
An engine according to claim 1, further comprising a center shaft in said casing and rotatable with said casing.
Claim 6
Dependent Claim
35 words
An engine according to claim 4, further comprising a stationary tubular support member disposed around said center shaft, and a support member external of said casing connected to one end of said tubular support member.
Claim 7
Dependent Claim
31 words
An engine according to claim 5, wherein said rotatable casing is comprised of three casing sections, at least one of said casings sections being rotatably mounted on said tubular support member.
Claim 8
Dependent Claim
58 words
An engine according to claim 1, wherein the vanes increase in size progressively radially outwardly from one variable volume chamber to the next, said vanes having an arcuate configuration and tapering outwardly from said vane holder shafts to the ends thereof and having a configuration conforming to the largest transverse cross section through the associated variable volume chamber.
Claim 9
Dependent Claim
79 words
An engine according to claim 1, further comprising passage means to transfer motive fluid from a region of decreasing volume of the first variable volume chamber, as viewed in the direction of casing rotation, and to introduce said motive fluid to the next variable volume chamber substantially in its region of smallest transverse cross section and in which region the vanes in said chamber are disposed in a plane substantially perpendicular to the axis of rotation of said casing.
Claim 10
Dependent Claim
53 words
An engine according to claim 1, further comprising an internal ring gear connected to said casing, a bevel gear fixed to each vane holder shaft, and interconnecting means between said ring gear and said bevel gears to drive said bevel gears and to rotate said vane holder shafts upon rotation of said casing.
Claim 11
Dependent Claim
66 words
An engine according to claim 9, wherein said interconnecting means include a plurality of planetary gears meshing with said internal ring gear, a stationary sun gear about which said planetary gears rotate, and a driving bevel gear rotated by movement of said planetary gears about said sun gear, said driving bevel gear being in operative engagement with the bevel gears fixed to said vane holder shafts.
