Patent number: 8689763Abstract: The rotary engine includes a circular stator, a circular rotor rotating about the stator; the rotor and the stator being separated by a circular cylinder and at least one element with two flanges. The rotor includes two compression pistons attached to the inner surface of the rotor. These two pistons are located at the two extremities of a first diameter of the rotor and kept substantially in contact with the outer surface of the stator. The stator includes a recess at each extremity of a diameter. Each recess forms a compression chamber with the compression piston positioned at the end of the recess in the direction of rotation of the rotor and one of the flanges of the element with two flanges, referred to as the cylinder head flange. The motive force is applied to the compression piston when the pressure of the gases inside the compression chamber is suddenly increased to a predefined value.Type: GrantFiled: September 18, 2009Date of Patent: April 8, 2014Inventor: Henri Pandolfo

Patent number: 8136503Abstract: An internal combustion engine of two perpendicular, toroidal cylinders intersecting at two junctions with each cylinder containing one piston filling half of its volume. The pistons are 180 degrees out of phase; each alternately occluding one intersection or the other. Each piston completes a full power, exhaust, intake, and compression stroke in one revolution. Endplates of 45 degrees allow the combustion chamber junction to be permanently filled and sealed at all times; first by one piston, then by the tips of both pistons as the complementary-angled endplates tangentially slide past one another, and then by the other piston. Compressed gases are shunted into the crossing cylinder's combustion chamber. Both pistons orbit continuously, one-way. Airflow is also one-way. Each piston is mounted to a sealed, 360-degree, counterbalanced ring gear. One ring gear is positioned centrally and the other peripherally to prevent interference. These maintain coordination between the pistons and provide output.Type: GrantFiled: April 10, 2008Date of Patent: March 20, 2012Inventor: Craig Louis Althen

Publication number: 20100111743Abstract: The invention provides a toroidal intersecting vane machine incorporating intersecting rotors to form primary and secondary chambers whose porting configurations minimize friction and maximize efficiency. Specifically, it is an object of the invention to provide a toroidal intersecting vane machine that greatly reduces the frictional losses through meshing surfaces without the need for external gearing by modifying the function of one or the other of the rotors from that of “fluid moving” to that of “valving” thereby reducing the pressure loads and associated inefficiencies at the interface of the meshing surfaces. The inventions described herein relate to these improvements.Type: ApplicationFiled: August 3, 2009Publication date: May 6, 2010Inventor: Alexander P. Doohovskoy

Patent number: 7703433Abstract: The rotary internal combustion engine is a rotary internal combustion engine that uses the unique combination of multiple rotors on a vertical axis with piston vanes, which are intersected by horizontally oriented valve rings so that rotating rotors intersect gaps on the rotating valve rings, thus creating the intake compression and power and exhaust cycles on this internal combustion engine. The unique design allows the motor to operation as either a motor or pump. High volume of compressed air virtually eliminates the need for a storage tank. These engines are an elegant solution that fulfills the century long quest for quiet, clean, highly efficient rotary power. When available, the demand for the benefits of rotary piston power in air, surface, and marine applications, will be immediate and rewarding.Type: GrantFiled: February 26, 2008Date of Patent: April 27, 2010Inventor: Richard Colman Webster

Patent number: 6390794Abstract: A rotary piston assembly including a piston housing with a central axis, and an annular chamber defined about the central axis. A pair of pistons are disposed about 180 degrees apart from one another within the annular chamber and rotate about the central axis a first angular velocity. The assembly also includes an abutment housing including a gap defined in its peripheral wall structure, and structured to rotate about an abutment axis at a second angular velocity. The abutment housing overlaps the piston housing and rotates therethrough to define an interior chamber therebetween, the first and second angular velocities being defined relative to one another so that the gap of the abutment housing rotates through the annular chamber when each of the pistons passes into and out of the interior chamber, thereby allowing the pistons to pass into and out of the interior chamber through the gap.Type: GrantFiled: November 22, 1999Date of Patent: May 21, 2002Inventor: Andrew Chin

Patent number: 5205724Abstract: Revolving piston compressor, which consists of two hollow rings when joined, form a tunnel or "sleeve" within which a curved piston circulates. A transversely disposed disc turns in synchronized fashion with the piston to form a wall which prevents the gas acted upon by the piston from travelling around through the sleeve. As the piston approaches the disc, the disc presents a "window", which allows the piston to pass. Once the piston has passed, the disc again forms a wall, closing the compression cycle. Because the piston cannot be physically engaged from the outside, it is moved via a moving magnet.Type: GrantFiled: December 31, 1991Date of Patent: April 27, 1993Inventor: Esteban T. Alexander
