ABSTRACT:
A rotary engine is comprised of at least one rotor assembly including a drum rotor and a cylinder rotor in internal contact with the drum rotor. The drum rotor bounds, with the cylinder rotor, and a crescent shaped working chamber and an annular working chamber, with the inner surface of the housing. The annular working chamber includes a first segmented annulus portion, a second segmented annulus portion of greater width than the first portion, and a transition portion of gradually increasing width connecting one end of first and second segmented annulus portions. A portion of the inner surface of the housing is inwardly projected between another end of first and second segmented annulus portions to come into contact with the periphery of the drum rotor. In the annular chamber is a further vane which is pivoted to the drum rotor to swing about an axis parallel to the axis of the drum rotor so as to intermittently interrupt communication between the crescent shaped chamber and annular chamber as well as to run expansion and exhaust strokes simultaneously.
