Abstract

889,246. Rotary internal-combustion engines. HARDY, C. C. M. Oct. 12, 1960 [July 12, 1959], No. 8676/59. Class 110 (2). A rotary I.C. engine including a compressor, combustion chamber, and a turbine, comprises a compressor A having a pair of intermeshing screw-like conical rotors 1, 2 positioned in a conical casing 3, to define a plurality of pockets 17 of decreasing volume from the air intake end 9 to the compression chamber 19 and a turbine B having a pair of similar rotors 4, 5 defining with a conical casing 6 a plurality of pockets 18 of increasing volume from the combustion chamber to the outlet 10. Fuel injected into the combustion chamber 19 through injectors 20 mixes with the compressed air and the mixture ignited either by ignition means or by cornpression ignition rapidly expands to rotate the turbine which through a shaft 11 drives the compressor and a power take-off (not shown) to do useful work. A seal may be provided between the casings and the peripheries of the rotors by actual contact, by spring-loaded sealing strips located in rotor grooves or by roughening the peripheral surfaces of the rotors to cause a turbulent boundary layer of air or gas. With the latter method, since there is no mechanical friction between relatively moving parts, the engine can move at high speeds without danger of seizure, overheating or wear and lubrication between the parts is then unnecessary. Moreover manufacturing tolerances may be greater so that the casings and rotors may be manufactured from centrifugal castings or by means of mould powder metallurgy. Also, non- metallic materials such as ceramics or porous or semi-porous refractory materials may be used for these parts. The rotors may be axially adjustable by means of a differential screw and a centrally splined portion of the shaft 11. The casings may have water-cooled passages 21. Alternatively to provide gradually decreasing volume pockets 17 and gradually increasing volume pockets 18, the rotor shafts may be parallel and the pitch of the rotors varied along the lengths of the shafts, or the shafts may be parallel and tapered. A modified construction includes three intermeshing rotors both for the compressor and the turbine.
