Patent ID: 7832368

Claim:
A two-stroke opposite radial rotary-piston engine comprising: a module including: stationary housing means; a stationary cylinder block assembled with the stationary housing means, said stationary cylinder block including: an intake channel and an exhaust channel; two cylindrically shaped sleeves, wherein each of two cylindrically shaped sleeves further comprises: inner sidewalls, an inlet window and an outlet window of predetermined sizes and configurations, being positioned in the inner sidewalls at predetermined locations, wherein said inlet and outlet windows correspondingly communicate with said intake channel and said exhaust channel; two pairs of pistons, wherein each of the pistons from said two pairs of pistons has a rod and a head, wherein said head is situated oppositely to the rod, wherein each pair of the pistons slidingly disposed within one of said sleeves so that the rods facing the upper and lower openings of the corresponding sleeve, wherein each of said pair of pistons is oppositely linearly movable in relation to each other forming a common chamber defined by the heads of the pistons and a portion of the inner sidewalls of the sleeve is positioned between the heads of the pistons; two pairs of guiding bearings essentially stationed on the block, wherein said rods operatively linearly run within said guiding bearings; a rotor having an inner operation surface formed by a predeterminedly curved line of a closed type having a transverse axis, wherein said rotor on the frontal part of its outer surface includes a peripheral concaved surface portion formed therein along said curved line; two T-like traverses so mounted that pair-wise spanning said rods attached thereto, wherein said traverses are associated with said rotor, wherein each of said traverses includes a protrusion, having a convex spherical surface in its lower portion operatively cooperating with said concaved surface portion, wherein a predetermined clearance between said concaved surface portion and said convex spherical surface of the protrusion is operatively provided; said engine further comprising: a power takeoff shaft rotatable supported substantially by the stationary housing means of said module; wherein said rotor is fixedly mounted on the takeoff shaft; and two support bearings, each coupled to one of said traverses, wherein each of said two support bearings includes an external bushing operatively rolling over the inner surface of the rotor, thereby propelling the rotor.
