Abstract
Abstract Disclosed is a rotary engine comprising a rotor, a plurality of pistons angularly mounted in the rotor, an actuator mounted for eccentric rotation relative to the axis of rotation of the rotor, a blower, a transverse actuator pin connecting each piston to the actuator, and a plurality of fixed pins connecting the rotor to the actuator. The fixed pins are mounted on the rotor, pass through clearance holes in a rotor disc which acts as a blower, and carry extension gears which mate with internal gears mounted in the actuator. Accordingly, rotation of the rotor causes rotation of the blower and of the actuator.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
119 words
A rotary engine comprising: (a) a rotor mounted for rotation about a first axis; (b) a plurality of pistons angularly mounted in said rotor; (c) an actuator mounted for rotation about a second axis which is parallel to but eccentrically spaced from the first axis; (d) a blower mounted for rotation about the first axis; (e) a transverse actuator pin connecting each piston to said actuator; and (f) a plurality of transverse fixed pins (i) mounted on said rotor, (ii) passing through clearance holes in said blower, and (iii) having extension gears at the ends thereof which mate with internal gears mounted in said actuator, whereby rotation of said rotor causes rotation of said blower and of said actuator.
Claim 2
Dependent Claim
119 words
A rotary engine comprising: (a) a rotor mounted for rotation about a first axis; (b) a plurality of pistons angularly mounted in said rotor; (c) an actuator mounted for rotation about a second axis which is parallel to but eccentrically spaced from the first axis; (d) a blower mounted for rotation about the first axis; (e) a transverse actuator pin connecting each piston to said actuator; and (f) a plurality of transverse fixed pins (i) mounted on said rotor, (ii) passing through clearance holes in said blower, and (iii) having extension gears at the ends thereof which mate with internal gears mounted in said actuator, whereby rotation of said rotor causes rotation of said blower and of said actuator.
Claim 3
Dependent Claim
35 words
A rotary engine as recited in claim 1 wherein the working faces of said pistons contain asymmetric indentations which cause the force of the expanding gases to push the piston transversely as well as longitudinally.
Claim 4
Dependent Claim
33 words
A rotary engine as recited in claim 2 wherein said rotor is contained in an engine block and wherein said asymmetric identations are curved to match the inner walls of the engine block.
Claim 5
Dependent Claim
29 words
A rotary engine as recited in claim 3 wherein said asymmetric indentations lead to the edges of said pistons which are in the direction of rotation of said rotor.
Claim 6
Dependent Claim
29 words
A rotary engine as recited in claim 2 wherein said asymmetric indentations lead to the edges of said pistons which are in the direction of rotation of said rotor.
Claim 7
Dependent Claim
17 words
A rotary engine as recited in claim 1 and further comprising a supercharger driven by said rotor.
Claim 8
Dependent Claim
79 words
A rotary engine as recited in claim 1 wherein said rotor is contained in an engine block and said pistons are contained in piston passageways which open to the peripheral exterior of said rotor, the portion of said piston passageways between the radially outer faces of said pistons when at their radially outer positions and said engine block serving as combustion spaces, said rotary engine further comprising means for regulating the quantity of gas admitted to said combustion spaces.
Claim 9
Dependent Claim
94 words
A rotary engine as recited in claim 1 wherein said rotor is contained in an engine block and said pistons are contained in piston passageways which open to the peripheral exterior of said rotor, the portion of said piston passageways between the radially outer faces of said pistons when at their radially outer positions and said engine block serving as combustion spaces, said rotary engine further comprising: (a) a supercharger driven by said rotor and (b) means for regulating the mixture of air and exhaust gas returned to said combustion spaces by said supercharger.
