783,913. Rotary engines. CROSSLAND, D. June 6, 1956 [June 6, 1955], No. 16152/55. Class 110 (2). A rotary internal-combustion engine comprises a compressor chamber C and an engine chamber E, each containing an eccentric rotor 23 or 24 respectively, provided with radiallysliding vanes 43. In Fig. 6 the casings also rotate. The rotors are provided with end plates 38 ... 41, and the two chambers are - separated by a disc 42. Transfer ports, for the compressed gas, are provided in plates 39, 41 and the disc 42. The gases may be fired by a sparking plug 48, through a cam 58, or through compression ignition means. The compressor and engine casings 25, 26 are eccentric at different angles, Fig. 4 (not shown). The spring- pressed vanes 43 are provided with slippers 45. A flywheel 56 is fixed to the shaft 20. Compressed gas from the chamber AC passes through the transfer ports in the discs 39, 41, 42 to an inlet 50, and the burnt gas is exhausted through a pipe 49. A water jacket 46 has an inlet 54 and an outlet 55. Spring-pressed seals 57 and resilient packings 37 are located where shown. In Fig. 6 the compressor and engine rotors 80, 81 are mounted on separate shafts 82, 83, which are off-set as shown. The casings are driven in the same direction as the rotors, through gearing 121, 124. The end wall of casing 91 contains centrifugal vanes 96 which are supplied with fuel mixture entering an inlet 97. This is delivered to the compressor through ports 98, 99. Transfer ports, to the engine chamber, are arranged in discs 88, 105, 111. The exhaust port 113 leads to a jacket 114 provided with guide vanes 119 leading to an outlet 120. Cooling air enters through a port 136 into a space containing centrifugal vanes 137 and passes through an outlet 138 into an outer chamber containing baffles 139, 140 being discharged at 141.
