20140076270 | ROTARY MACHINE - A rotary machine is provided which includes a chamber. The chamber includes an island having an island outer surface. The outer surface is an elongated convex shape. The island includes a crankshaft port. The chamber includes a front-plate attached to a front surface of the island. A concave shaped contour is included, which is biased toward the island outer surface and which rotates with respect to the island. A working volume is defined between an inner surface of the contour and the outer island surface. At least one front-plate engaging bearing is provided, which extends from a front surface of the movable contour and over a guide edge of the front-plate. The front-plate engaging bearing engages the guide edge during a combustion cycle. | 03-20-2014 |
20130251579 | IDAR-ACE INVERSE DISPLACEMENT ASYMMETRIC ROTATING ALTERNATIVE CORE ENGINE - The disclosure provides engines or pumps that includes a rotatable shaft defining a central axis A, the shaft having a first end and a second end. The shaft can have an elongate first island disposed thereon. The first island can have a body with a volume generally defined between front and rear surfaces that are spaced apart. The front and rear surfaces can lie in a plane parallel to a radial axis R. The perimeters of the front and rear surfaces can define a curved perimeter surface therebetween. The engine or pump can further include a front side plate disposed adjacent to the front surface of the first island, and a rear side plate disposed adjacent to the rear surface of the first island. The engine or pump also includes a first contour assembly disposed between the front side plate and the rear side plate. | 09-26-2013 |
20100242897 | INVERSE DISPLACEMENT ASYMMETRIC ROTARY (IDAR) ENGINE - An inverse displacement asymmetric rotary engine is provided which includes a chamber. The chamber includes a stationary island having an island outer surface. The outer surface is an elongated convex shape. The island includes a crankshaft port spaced from a center of the island. The chamber includes a front-plate attached to a front surface of the island. A concave shaped movable contour is include, which is biased toward the island outer surface and which revolves about the island. A working volume is defined between an inner surface of the contour and the outer island surface. At least one front-plate engaging bearing is provided, which extends from a front surface of the movable contour and over a guide edge of the front-plate. The front-plate engaging bearing engages the guide edge during a combustion cycle. | 09-30-2010 |
