<p>A double-acting, rotating piston (4) reciprocating in a cylinder (2) with the motion of the piston providing the valving action of the Sibling Cycle through the medium of passages between the piston and cylinder wall. The rotating piston contains regenerators (8) ported to the walls of the piston. The piston fits closely in the cylinder at each end of the cylinder except in areas where the wall of the cylinder is relieved to provide passages between the cylinder wall and the piston leading to the expansion (60) and compression spaces (62), respectively. The piston reciprocates as it rotates. The cylinder and piston together comprise an integral valve that sequentially opens and closes the ports at the ends of the regenerators alternately allowing them to communicate with the expansion space and compression space and blocking that communication.</p> |
