Abstract: The internal combustion engine allows charging with an air/fuel mixture into the combustion chamber while the combustion chamber is under combustion pressure and outputs power virtually continuously at the same time, i.e., the novel engine has an almost continuous fuel feed and, due to substantially continuous combustion, it also has an almost continuous power output. The fuel and/or air is injected by way of mutually intertwined worm spindles that form a fluidtight displacement system. The blades of the impeller system are almost flat, i.e., their attack angle relative to backpressure is close to perpendicular so that they will turn quite freely in the forward direction, but will not be turned backwards by a pressurized backflow. The impeller rotation that is introduced via the spindle shafts nevertheless leads to a volume displacement towards the chamber to be pressurized or to be subjected to equal pressure.
