Internal combustion engine having rotating pistons

Patent ·
OSTI ID:6396596
A rotational piston-combustion engine is described rotating about its center line comprising an annular cylinder of pistons fixedly mounted relative to one another and movable as a unit to sweep out circular paths within the annular cylinder. An actuation shaft coaxial with the axis of the annular cylinder and rigidly connected to the pistons, separating walls adapted to move substantially radially inwardly and outwardly to divide the inner space of the annular cylinder into respective chambers. An outlet valve upstream of each separating wall with respect to the rotational direction of the piston. An inlet valve downstream of each separating wall, an ignition means, means to retract the separating walls and to allow the passage of a piston an immediately to reinsert them into the cylinder chamber, and a compression chamber, and the interior of the sealed housings fixedly connected with the annular cylinder and receiving the separating walls connected each with a collection chamber. They are disposed outside of the cylinder which in its turn is connected with the respective induction opening through a pressure valve.
