IDAR-ACE inverse displacement asymmetric rotating alternative core engine

A rotary machine, comprising:

• a) a rotatable main shaft defining a central axis having an island disposed thereon, the island having a body with a volume generally defined between front and rear surfaces that are spaced apart along the main shaft, the front and rear surfaces lying in a plane parallel to a radial axis perpendicular to the central axis, the front and rear surfaces having a rounded, non-circular shape, the perimeters of the front and rear surfaces defining a curved peripheral surface therebetween;
• b) a front side plate disposed at the front surface of the island, the front side plate having a first cam-shaped perimeter;
• c) a rear side plate disposed at the rear surface of the island, the rear side plate having a second cam-shaped perimeter;
• and
• d) a contour assembly disposed between the front side plate and the rear side plate, the contour assembly having:
• (i) a body defining a concave inwardly facing surface that faces the curved peripheral surface of the island;
• (ii) a front side facing the front side plate;
• (iii) a rear side facing the rear side plate;
• (iv) a first cam follower extending outwardly from the contour assembly including a first rotating bearing disposed on a first spindle attached to the contour assembly, wherein the first rotating bearing of the first cam follower rolls along and follows the first cam shaped perimeter of the front side plate to maintain substantially uniform spacing between the contour assembly and curved peripheral surface of the island when the island, the main shaft, the front side plate and the rear side plate rotate about the central axis with respect to the contour assembly;
• and
• (v) a second cam follower extending outwardly from the contour assembly including a second rotating bearing disposed on a second spindle attached to the contour assembly, wherein the second rotating bearing of the second cam follower rolls along and follows the second cam shaped perimeter of the rear side plate to maintain substantially uniform spacing between the contour assembly and the curved peripheral surface of the island when the island, the main shaft, the front side plate and the rear side plate rotate with respect to the contour assembly about the central axis, wherein the concave inwardly facing surface of the contour assembly, the curved peripheral surface of the island, the front side plate and the rear side plate cooperate to form a working volume.

• b) a front side plate disposed at the front surface of the island;
• c) a rear side plate disposed at the rear surface of the island, the front and rear side plates being attached to at least one of the main shaft and the island such that the front and rear side plates always rotate with the main shaft and the island during engine operation of the rotary machine;
• d) a contour assembly disposed between the front side plate and the rear side plate, the contour assembly having a body defining a concave inwardly facing surface that faces the curved peripheral surface of the island, the concave inwardly facing surface, the curved peripheral surface of the island, the front side plate and the rear side plate cooperating to form a working volume, the main shaft and island being configured to rotate with respect to the contour assembly;
