Title: Rotary piston internal combustion engine with compressor
Inventor: MOUMTZIS IOANNIS STYLIANOU
IPC: F02B57/08
Filed: 2002-06-19
Abstract: he invention relates to a piston internal combustion motor composed of a central steady, non-rotating shaft 13 having the shape of a flywheel and a rotor bearing the cylinders in peripheral star arrangement and rotating around the central steady shaft. The shafts operate in pairs: one combustion cylinder 11 for the combustion of the mixture and another cylinder functioning as compressor 12 supplying the corresponding combustion cylinder -via the feed conduit 26- with mixture. The exhaust ports21 are monitored by the moving lamina 23 adequately timed to improve the replenishment of the combustion cylinder and prevent the non-combusted mixture from coming out. For preventing the inertia forces of the linear reciprocation motion, the pistons and all accessories are moving rotationally. For each pair of cylinders, which are diametrically and coaxially positioned on the rotor, there is utilised a double piston having two oppositely located heads 16,17. The mass of the rotor replaces the flywheel so that the motor's weight is significantly reduced. All points of the motor are lubricated as in the traditional 4-stroke motors. Another application of the rotary piston operation assisted by cylinders functioning as compressors offers a rotary piston compressor exempt from the inertia forces created by the linear reciprocation motion.
