Abstract: This invention relates to improvements on rotary engines having annular cylinders, each having at least two pistons drivable in rotation therein, the pistons being fixed respectively to concentric shafts that are thereby independently rotated around their concentric axis. Each of the concentric shafts extends through all the cylinders, which are formed by rotatable discs within an annular master cylinder. The concentric shafts are supported for rotation by bearings mounted within the end housings of the annular master cylinder with each of the concentric shafts having an end extending through one of the end housings for connecting to means for independently coupling the two concentric shafts to a common eccentric shaft.

Abstract: An angular cylinder piston combination is disclosed for providing compression and expansion chambers in a large number of items, such as compressors, pumps, internal and external combustion engines, hydrostatic generators, air motors, and the like, in which compression and expansion chambers are formed angularly, inside a cylindrical drum which rotates at substantially uniform velocity "Wo" and connected to the output shaft. The chambers are formed between N outer radial pistons provided by the drum and N inner radial pistons attached to an inner rotor which accelerates and decelerates from zero velocity to a velocity "2Wo" with respect to a stationary housing. The inner rotor comprises a sleeve overlaying the output shaft and rotatably displacable in relationship therewith. A single port per chamber provides intake and exhaust as it comes into juxtaposition with slots, azimouthally cut on the base of a stationary housing. The inner radial pistons, oscillating within the angle subtended between the outer pistons, do not cross the ports. Lubricating oil can then be permitted to run between a pair of sealing elements positioned along those edges of the pistons which slide with respect to other members of the angular cylinder. The application of this angular cylinder provides the basis of an improved Tri-Rotor device.

Abstract: A rotary engine having an annular cylinder with more than one piston drivable in rotation therein, the pistons being fixed respectively to concentric hollow shafts that are thereby independently rotated thereby around their concentric axis. Crank members, at least one per piston, are mounted in ball races that are eccentrically fixed to the respective concentric shafts, the crank members extending diametrically across their respective concentric shafts. An eccentric drive shaft displaced radially from the axis of the concentric shafts mounted for rotation in and extending through said concentric shafts, the eccentric shaft defining diametric holes for slidably engaging the crank members without loss of rotational motion while allowing the crank members to move simultaneously toward the away respectively from the eccentric shaft axis at constantly varying speeds and directions to thereby rotate the eccentric shaft. Both eccentric and concentric shafts are mountable in ball races fixed in a motor housing and the ends of concentric shafts for support of all shafts at their respective ends. As many as four pistons can be mounted in each cylinder respectively fixed to a concentric shaft and collars sleeved for independent rotation on said shaft, and additional cylinders can be added to extension of an end of the eccentric shaft.

Abstract: An eccentric rotor vane device that may be employed as pumps, blowers (or compressors), engines, or motors, characterized by an improved seal structure; in addition to conventional main chamber; first and second ports communicating with the main chamber; a plurality of annularly related radial vanes, independently pivotal and rotatable about a vane axis within the main chamber; a rotor that is eccentrically mounted with respect to the main chamber; a power delivery shaft connected with the rotor. The improved seal means, in specific embodiments, comprises a plurality of cylindrical rollers that serve as vane guides intermediate each pair of adjacent vanes. The cylindrical rollers adjacent each face of each respective vane engages its lateral face such that a satisfactory seal is made as the roller traverses radially inwardly and outwardly along the lateral face of the vane. Thus, the plurality of rollers serve as at least a part of a piston as well as an interdigitating means for effecting a change in volume of a subchamber defined intermediate the respective vanes, rollers, and interior wall in the main chamber. Also disclosed are improved vane structures for maintaining more nearly perfect seals for long service life.

Abstract: A SELF-CONTAINED POWER SYSTEM PARTICULARLY SUITABLE FOR USE AS A VEHICLE DRIVE SYSTEM CONSISTING OF A SELFPOWERED AND SELF-REGULATING GAS GENERATOR OF THE ROTARY PISTON TYPE DELIVERING HOT COMPRESSED GAS FOR ANY DESIRED PURPOSE, SUCH AS THE POWERING OF COMPRESSED GAS MOTORS WHICH MAY ALSO BE OF THE ROTARY PISTON TYPE, CAPABLE OF INDIVIDUALLY DRIVING EACH WHEEL OF A VEHICLE. BOTH THE COMPRESSED GAS MOTORS AND THE GAS GENERATOR INCORPORATE ROTATING SETS OF VANE PISTONS MOVING IN AN ANNULAR CHAMBER, AND ALTERNATELY ACCELERATING AND DECELERATING WHILE MOVING AROUND THE ANNULAR CHAMBER. THE ROTATING SETS OF ACCELERATING AND DECELERATING PISTONS ARE CONTROLLED BY THEIR ENGAGEMENT WITH CONNECTING MEMBERS MOUNTED FOR PLANETARY ORBITAL ROTATION WITHIN THE STATOR HOUSINGS OF THESE DEVICES. AT LEAST ONE OF THESE CONNECTING MEMBERS IS ENGAGED WITH AT LEAST ONE CENTRAL CRANKSHAFT FOR CONTROLLING THIS ORBITAL ROTATION AND DELIVERING TORQUE TO OR FROM THE DEVICE, WHILE ONE OR MORE OTHER CONNECTING MEMBERS ARE "FLOATING" CONNECTING MEMBERS ENGAGED ONLY WITH THE PISTON SETS, AND NOT CONNECTED DIRECTLY WITH OTHER CONNECTING MEMBERS OR CRANKSHAFTS OR WITH THE STATOR HOUSING. THE GAS GENERATOR INCORPORATES A UNIQUE COMPRESSED GAS BLEED FEATURE PROVIDING SELF-REGULATING OPERATION FOR EFFICIENT DELIVERY OF COMPRESSED GAS AT A PREDETERMINED PRESSURE LEVEL. THE COMPRESSED GAS MOTOR DEVICES INCORPORATE SIMPLE REVERSING MEANS AND MEANS FOR AUTOMATIC ADJUSTMENT OF PORT OPENINGS AND CLOSINGS FOR MOST EFFICIENT OPERATION AT ANY GIVEN PRESSURE, AS WELL AS SIMPLE SPEED REDUCER MEANS FUNCTIONING TO REDUCE THE HIGH ROTATIONAL VELOCITY OF THE CRANKSHAFTS IN THESE GAS MOTORS TO MORE USEFUL OUTPUT VELOCITIES FOR SUCH PURPOSES AS DRIVING THE WHEELS OF A MOVING VEHICLE. OTHER USEFUL FEATURES OF THESE ROTARY PISTON DEVICES INCLUDE POSITIVE LUBRICATION MEANS FOR DRAWING OIL FROM AN OIL SUMP DURING OPERATION, SPLASHING IT OVER THE MOVING PARTS DURING OPERATION, BUT RETURNING IT TO A SUMP IN WHICH IT IS RETAINED WHEN THE DEVICE IS NOT IN OPERATION.
