Title: A stator and rotor internal-combustion engine
IPC: F02B53/00
Filed: 1930-04-22
Abstract: 352,574. Rotary engines. LANCASTER, T. S., 39, Methley Terrace, Chapel- Allerton, Leeds. April 22, 1930, No. 12364. [Class 110 (ii).] Fixed-abutment type ; packing drums and vanes ; working-fluid supply.-A rotary internal-combustion engine comprises a hollow eccentric rotor 3 and sliding vanes 4 which are controlled by a crank shaft 9 the axis of which is eccentric to both the rotor and the outer casing. The crank shaft revolves at twice the speed of the rotor. Internally cut gearwheels 27, 28 on the driven shaft 25 mesh with gears 26, 29 on the rotor and crank shaft respectively, the latter being attached by means of a vernier coupling. In an alternative gearing arrangement a lay-shaft is incorporated. Air enters through a port 2A and liquid or gaseous fuel by way of one or several pipes 33 in the periphery of the casing and in the end wall, and the mixture is compressed and initially fired by a sparking plug near the bottom of the casing. The combusted gases expand and are exhausted through a port 32 to an exhaust box 18, a baffle-plate or guide 19 being provided in the latter. Part of the incoming air scavenges the rotor cavities and flows directly to exhaust. When the engine is running, the sparking plug is blanked off by a rotary valve and firing of the combustible gases is secured by hot gases being passed back through tubes 22, 23, 24. A byepass leads from the plug pocket to a port 34 to exhaust gas contained in the plug socket and to reduce the compression when necessary. Packing pieces are fitted to the sides, tips and ends of the sliding vanes 4, and shoes 7 are hinged to side-plates 5 on the vanes. Packing segments 14 are inserted in grooves in the rotor ends. The casing is air or water cooled by two separate systems, one for the expansion side and one for the compression side, the former side being kept warmer than the compression side. Lubricating oil is fed through the crank shaft and up grooves in the plates and is also supplied through ports 36 in the end walls of the casing. Oil contained in the exhaust gases returns to the engine by gravity or is flung into gutters 66 in the exhaust box 18 and is led to a sight glass before returning to the engine. The sparking plug may be allowed to function continuously and the firing tubes 22, 23, 24 be blanked off. A carburetter may replace the fuel pipes 33 and a supercharger fitted to the engine. In the latter case the position of the inlet and exhaust ports is changed slightly. For a reversible engine the inlet and exhaust ports and sparking plug are duplicated on the other side of the line E F. Silencers may be fitted to the inlet and exhaust pipes which may be of considerable length.
