<p>923,197. Rotary engines and pumps. RESEARCH CORPORATION. Feb. 2, 1961 [Feb. 27, 1960; May 20, 1960], No. 3957/61. Class 110 (2). A rotary engine or pump comprises a block member 1, Fig. 8, a rotor 6, and end wall members 3, Fig. 4, wherein the inner surface 2 of the block member is divided into an even number of sectors, eight in Fig. 2, with each alternate sector AB, CD, EF, GH concaved at one specifically defined radius, O 0 B, and each alternate sector, BC, DE, FG, HA concaved at another specifically defined radius, O 1 B. The rotor 6, keyed to a shaft 5 and carried by bearings 4 supported by the end walls 3, is formed around its periphery with gear teeth 7 engageable with teeth 8 formed on the underside of piston members 9 urged outwardly into engagement with the surface 2 and having an outer curved surface corresponding to the larger of the two sector radii. The pistons, six in number, are each sealed by spring-loaded members 18 against the surface 2 and by spring-loaded members 14 against the end walls 3<SP>1</SP>. When operating as an I.C. engine, air is sucked in through inlets 21 and exhaust gases discharged through outlets 22, fuel admitted through ports 23 may be supplied through a carburetter and together with the compressed air ignited by a sparking plug or under fuel injection. On one complete revolution of the rotor clockwise, each piston completes two operational cycles, so that with the six pistons twelve operational cycles take place per revolution. With diametricallyopposed pistons firing simultaneously and the inlets 21 and outlets 22 symmetrically disposed, the rotor 6 is dynamically balanced.</p> |
