Abstract
Abstract An improved internal combustion rotary engine, of the kind wherein a housing contains in a cylindrical bore a control body effecting an oscillating cycle creating a series of combustion chambers, has at least three crank-shaped bodies placed intermediate the contacting surfaces between the end covers of said cylindrical bore and the central body sides; said crankshaped bodies are equidistantly arranged, partially and freely housed in respective recesses hollowed out in said covers, eccentric appendices of which, jutting out from the surfaces thereof, are freely included within respective recesses hollowed out from the central body sides, said central body also having radially and equidistantly arranged a plurality of swivelling dividing bodies associated with the surface of the housing internal cylindrical space; each of said dividing bodies, having a parallelepiped quadrangular and flattened configuration, is integral with a basic semi-circular cross-section body, freely included in a corresponding hollow of coincident cross-section cut off from the central body, while the upper portion of said dividing body swivellingly enters into a space offered by a further head body, also having a semi-circular cross-section and equally included in a coincident cross-section hollow existing in the housing wall; said dividing dividing basic and head bodies being interiorly provided with conduits associated with exhaust and injection operations.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
210 words
An improved internal combustion rotary engine including a housing having an interior cylindrical space; an end cover at each end of said interior space of said housing; an eccentric central body housed within said space and having flat sides parallel to said covers; at least three intermediate crank-shaped bodies equidistantly arranged between said covers and said central body partially and freely housed in respective recesses hollowed out in said covers, each body having an eccentric appendix jutting out from one surface thereof and freely included within respective recesses hollowed out from said flat sides of said central body; a plurality of swivelling dividing bodies radially and equidistantly disposed on said central body in spaced relation with the surface of said cylindrical space, each of said dividing bodies having a parallelepiped quadrangular and flattened configuration; a basic semicircular cross-section body integral with each dividing body and freely included in a corresponding hollow of coincident cross-section in said central body; a head body having a semicircular cross-section and included in a coincident cross-section hollow existing in said housing; said head body having a space swivelling receiving an upper portion of said dividing body; said dividing, basic and head bodies comprising separate conduit means for receiving inlet fluid and for discharging exhaust fluid.
Claim 2
Dependent Claim
210 words
An improved internal combustion rotary engine including a housing having an interior cylindrical space; an end cover at each end of said interior space of said housing; an eccentric central body housed within said space and having flat sides parallel to said covers; at least three intermediate crank-shaped bodies equidistantly arranged between said covers and said central body partially and freely housed in respective recesses hollowed out in said covers, each body having an eccentric appendix jutting out from one surface thereof and freely included within respective recesses hollowed out from said flat sides of said central body; a plurality of swivelling dividing bodies radially and equidistantly disposed on said central body in spaced relation with the surface of said cylindrical space, each of said dividing bodies having a parallelepiped quadrangular and flattened configuration; a basic semicircular cross-section body integral with each dividing body and freely included in a corresponding hollow of coincident cross-section in said central body; a head body having a semicircular cross-section and included in a coincident cross-section hollow existing in said housing; said head body having a space swivelling receiving an upper portion of said dividing body; said dividing, basic and head bodies comprising separate conduit means for receiving inlet fluid and for discharging exhaust fluid.
Claim 3
Dependent Claim
210 words
An improved internal combustion rotary engine including a housing having an interior cylindrical space; an end cover at each end of said interior space of said housing; an eccentric central body housed within said space and having flat sides parallel to said covers; at least three intermediate crank-shaped bodies equidistantly arranged between said covers and said central body partially and freely housed in respective recesses hollowed out in said covers, each body having an eccentric appendix jutting out from one surface thereof and freely included within respective recesses hollowed out from said flat sides of said central body; a plurality of swivelling dividing bodies radially and equidistantly disposed on said central body in spaced relation with the surface of said cylindrical space, each of said dividing bodies having a parallelepiped quadrangular and flattened configuration; a basic semicircular cross-section body integral with each dividing body and freely included in a corresponding hollow of coincident cross-section in said central body; a head body having a semicircular cross-section and included in a coincident cross-section hollow existing in said housing; said head body having a space swivelling receiving an upper portion of said dividing body; said dividing, basic and head bodies comprising separate conduit means for receiving inlet fluid and for discharging exhaust fluid.
Claim 4
Dependent Claim
210 words
An improved internal combustion rotary engine including a housing having an interior cylindrical space; an end cover at each end of said interior space of said housing; an eccentric central body housed within said space and having flat sides parallel to said covers; at least three intermediate crank-shaped bodies equidistantly arranged between said covers and said central body partially and freely housed in respective recesses hollowed out in said covers, each body having an eccentric appendix jutting out from one surface thereof and freely included within respective recesses hollowed out from said flat sides of said central body; a plurality of swivelling dividing bodies radially and equidistantly disposed on said central body in spaced relation with the surface of said cylindrical space, each of said dividing bodies having a parallelepiped quadrangular and flattened configuration; a basic semicircular cross-section body integral with each dividing body and freely included in a corresponding hollow of coincident cross-section in said central body; a head body having a semicircular cross-section and included in a coincident cross-section hollow existing in said housing; said head body having a space swivelling receiving an upper portion of said dividing body; said dividing, basic and head bodies comprising separate conduit means for receiving inlet fluid and for discharging exhaust fluid.
Claim 5
Dependent Claim
82 words
An improved internal combustion rotary engine as claimed in claim 1, characterized in that each of the bodies intermediate between the cover surfaces and the rotor sides are comprised of a cylindrical and flattened central body from one of the faces of which a cylindrical appendix is perpendicularly and coaxially projected, while from the opposite face a similar but eccentric appendix protrudes, said bodies being internally provided with a through conduit which is coaxial to and interiorly communicated with both said appendices.
