Abstract
Abstract A rotary machine for use as a pump or motor wherein a hollow rotor is rotatable within a casing and combines with the latter to define therebetween an annular chamber. A vane or arm extends from the rotor for rotation therewith about the annular extent of the chamber and a fluid inlet passageway communicates between the hollow of the rotor and the chamber on one side of the vane or arm for passing fluid into the chamber on said one side of the vane. An outlet is provided in the casing for the egress of fluid from the chamber on the other side of the rotor vane.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
272 words
A rotary machine comprising a generally cylindrical casing, a centrally hollow shaft defining a rotor in coaxially spaced relation within said casing, a plurality of coaxial annular walls spaced longitudinally along said shaft and extending from said shaft toward said casing to define therebetween a plurality of generally annular chambers surrounding said rotor, a plurality of vanes arranged in longitudinal spaced relation along said rotor and each extending radially from said rotor between the adjacent annular walls and entirely across said chamber for rotAtion with said rotor about the annular extent of said chamber in equally angularly spaced relation with respect to each other, said rotor having a plurality of inlet passageways each communicating generally radially between said hollow and said chamber adjacent to and on one side of a respective vane, a plurality of rotary generally disc-shaped heads each extending radially inwardly across one region of a respective one of said chambers for rotation through said one region and having an edge notch configured to receive the associated one of said vanes when the latter passes through said one region, timing means operatively connecting said rotor and heads for entry of said vanes in said recesses, and a pipe extending coaxially into the hollow of said rotor and having radial ports communicating with said inlets during limited portions of rotor rotation for passing fluid to said chambers between each of said heads and the associated said one side of said vane, said casing having outlet passageways adjacent to said disc-shaped heads communicating with said chambers for passing fluid from said chambers between said heads and the other sides of said vanes.
Claim 2
Dependent Claim
272 words
A rotary machine comprising a generally cylindrical casing, a centrally hollow shaft defining a rotor in coaxially spaced relation within said casing, a plurality of coaxial annular walls spaced longitudinally along said shaft and extending from said shaft toward said casing to define therebetween a plurality of generally annular chambers surrounding said rotor, a plurality of vanes arranged in longitudinal spaced relation along said rotor and each extending radially from said rotor between the adjacent annular walls and entirely across said chamber for rotAtion with said rotor about the annular extent of said chamber in equally angularly spaced relation with respect to each other, said rotor having a plurality of inlet passageways each communicating generally radially between said hollow and said chamber adjacent to and on one side of a respective vane, a plurality of rotary generally disc-shaped heads each extending radially inwardly across one region of a respective one of said chambers for rotation through said one region and having an edge notch configured to receive the associated one of said vanes when the latter passes through said one region, timing means operatively connecting said rotor and heads for entry of said vanes in said recesses, and a pipe extending coaxially into the hollow of said rotor and having radial ports communicating with said inlets during limited portions of rotor rotation for passing fluid to said chambers between each of said heads and the associated said one side of said vane, said casing having outlet passageways adjacent to said disc-shaped heads communicating with said chambers for passing fluid from said chambers between said heads and the other sides of said vanes.
Claim 3
Dependent Claim
21 words
A rotary machine according to claim 1, said timing means comprising gearing interposed in driving relation between said rotor and head.
