Title: THE DRAW ROTARY ENGINE
Abstract:
A reciprocating piston rotary internal combustion engine; comprising a non-rotating circular cylinder engine block (16) containing a rotor (21) on which piston (32) reciprocate at right angles to the direction of centrifugal force, and parallel with the rotor, and at right angles to the direction of rotation of the rotor. These pistons form three sides of the combustion chamber (36) and the combustion chamber ignition blocks (24), (which are built on to the rotor (21)) along with rotor (21) form two more sides, finally the cylinder (16) forms the sixth side. Compression and decompression is affected by cams (28) on front and back plates (27) guiding pistons (32) by means of cam followers (33) built into the pistons. By altering cams (28) one can produce variable delays (pauses (37)) between the strokes of the combustion cycle or change the number of strokes in a given combustion cycle. The rotor (21) can have the blanks (23) recessed to allow for counterbalances to be inserted, and pistons (32) can have guide rails added to take the counterbalances.
