Abstract

Axially protruding and centrally cool able pistons rotate within a cylindrical main chamber. Each piston is individually kinetically linked to a flywheel. As the pistons are individually accelerated and decelerated along their continuous rotating path, rotating volumes between them angularly expand and contract. Inlets and outlets communicate fluid in correspondence with expansion and contraction phases of the rotating volumes. A low number of moving parts, area sealed volumes, no valves, balanced mass forces, smooth rotation and short force transmission paths between opposing mass forces provide for lightweight construction and high rotational speeds. Radial sliding secondary pistons of the kinetic linkage modulate secondary rotating volumes adjacent the main chamber for a dual stage thermodynamically efficient engine operation with intermittent fluid cooling or heating. Inlets and/or outlets may be angularly changed for variable compression and/or combustion engine peak pressures, expansion end pressure, for brake energy recycling and burst mode engine operation.
