Description:

Claim:

This invention relates to a rotary engine, the piston-wheel of which is composed of a thin disk which works steam-tight between two annular rims projecting from the inner surfaces of the cylinder-heads, and which is provided with one or more pistons, the ends of which are faced off to work steam-tight against the inner surfaces of the cylinder-heads, while their top and bottom edges are so shaped that they work steam-tight against the inner circumference of the cylinder and against the peripheries of the annular rims, the whole being so constructed that the weight of the piston-wheel is reduced as much as possible without reducing the effective area of the pistons and, furthermore, by using ground joints all packing is rendered superfluous, and the friction is reduced to the lowest possible point.
