Filed: 1935-06-25
Abstract: 445,450. Rotary internal-combustion engines. DRIEL, J. VAN, and VEEN, J. VAN DER, 11, Balowerti, Kediri, Java. June 25, 1935, No. 18189, [Class 110 (ii)] The engine comprises sliding vanes 12, a circular rotor 11 and an elliptical casing 10. The working fluid is fired at intervals separated by a rotor rotation of 360‹ Œ 360‹/n ,or a multiple of this angle, n being the number of combustion chambers in the casing. Scavenging and cooling air is introduced once or twice during every cycle. The opening and closing of the inlet, outlet, and scavenging ports may be effected by distribution discs driven by gear wheel transmission off the rotor shaft, which co-operate with ports in the casing walls. These ports may be formed as arcs situated at different radii on the end walls. In an alternative system, Fig. 10, cam operated valves may be used in place of the discs. Gears 20, 21, are keyed to the rotor shaft 19, and mesh with gears 22, 23, revolving freely on an axially slidable shaft 26. Cams 30, 31, are combined with gears 22, 23, and one of these cams actuates a bell-crank lever 34, through a push rod 32, to open an air valve 36. Further cams 37 or 38 on the gears act in a similar manner on push rods to actuate exhaust valves. In Fig. 8 air ports are shown at A, B, D, and a gas valve at C. Moving the arm 28 causes the shaft 26 to slide and changes over the cams, alters the ignition from 450‹ to 270‹ (for example) of rotor rotation. Cylindrical sleeves 40, 41, are attached to gears 23, 22, and are provided with electrical contact pieces 42, 43, which engage alternatively with the contact rollers 44, 45. The pieces 42, 43, are preferably in electrical contact with the gears and the casing 27. Sparking plugs may be placed either on the casing, or on the rotor. In the latter case the ignition circuit would be completed through slip rings. Cooling fins or a liquid jacket may be provided. The air pipes to the engine may pass through the jacket. Springs may be used to press out the vanes. The latter may be controlled by two pinions and racks, projecting pins engaging cam grooves, or sliding bevel-shaped members in contact with each other on the inner ends of the vanes. The engine may be modified for compression-ignition.
