Abstract (en)
[origin: WO8808074A1] An internal combustion engine has at least one piston (15, 16) which moves back and forth in a cylindrical piston bore (13, 14) and drives a rotationally supported crankshaft (30) through a connection rod (24, 25). The piston bore (13, 14) is arranged in a rotary element (10) rotationally supported in a housing (1). The rotary element (10, 17) and crankshaft (30) are cinematically coupled through a gear (40, 41, 42, 43) so that they can rotate in opposite directions (60 or 61). The piston bore (13, 14) arranged in the rotary element (10) communicates with an opening (20, 21) in the outer surface of the rotary element (10, 17) which moves past an inlet opening (50) and an outlet opening (51) in the housing (1) during rotation of the rotary element (10).
