Movable-abutment type; valves, distributing and cut-off; working-fluid supply.- Relates to rotary engines, pumps, &c. of the type in which a driving rotor and piston rotates continuously with the shaft and an abutment rotor and piston rotates with variable speed, the spaces between the two pistons forming the working chambers. The casing 1, Figs. 1 and 2, encloses two disk-like rotors 2, 3 carrying pistons A, B. The rotor 2 and piston A are fixed to the shaft 11, and the rotor 3 and abutment piston Bare loose thereon. An eccentric rotating ring 16 engages through the medium of swivel bearing-blocks 24, 25, rods 22. 23 fixed to the rotors 2, 3 respectively, and causes variable rotation of the piston Band consequent changes of volume in the working chambers 17, 18. In a modification, this differential rotation is obtained by elliptical gearing, and, in another form, by a stationary eccentric between the rotors having a loosely revolving ring with pins engaging slots in the rotors. The induction port 27, Fig. 2, and the exhaust are opened by cams 30 on shafts 37 actuated by spur gearing 40, 41. The cycle of operations, in the form in which the apparatus is used as an internal-combustion engine, is shown in Figs. 8, 9, and 10. The piston A is leading in Fig. 8 and moves to the position shown in Fig. 9, inducing a charge from the induction port 27 into the space 17. The abutment piston B meanwhile moves relatively slowly to the position shown in Fig. 9, and then, by relative acceleration, compresses the charge 17 as shown in Fig. 10, where it is ignited by a plug 42, driving the piston A forward, and exhausting at 35. In a modification, four pistons are employed, two on each rotor. Reference has been directed by the Comptroller to Specification 28287/02.
