Rotary engine
This patent describes an improved rotary engine. It comprises an annular master cylinder composed of a cylindrical housing, a continuous hollow outer concentric shaft, an outward end housing and an inward end housing; means to form a dynamically balanced disc piston assembly extending from the the outward end housing to the the inward end housing thereby dividing the the annular master cylinder into at least three separate gas tight cylinders formed by rotating discs, each cylinder having at least two pistons independently rotatable therein; means to isolate the unexpanded gases from any exit path into the housing of the piston controlling means; and wherein one of the pistons in each cylinder is connected directly to the the continuous outer concentric shaft to form a first piston assembly, the other of the pistons in each cylinder is connected to the discs which are connected to the end of an inner concentric shaft to form a second piston assembly, means for controlling the piston action by a common eccentric shaft such that as the pistons rotate they expand and reduce the distance between them thereby changing the volume between the pistons within each of the cylinders.
