Abstract

A Polygon Oscillating Piston Engine having multiple pistons on one of two oscillating disks. Each piston moves in a straight line along one of the sides of a polygon within a cylindrical chamber while the oscillating disks move in an arc about a central shaft. The difference in the straight motion of the piston and angular motion of the oscillating disk is accommodated by a slip sleeve within the piston that slides on a peg or bar mounted to each disk. The engine can be configured to operate as an internal combustion engine that uses diesel fuel gasoline or natural gas or it can be configured as an expander to convert high pressure high temperature gas to rotary power. This engines compact design results in a high power to weight ratio.
