At the other or right end, as viewed in Figure 4, the valve I9has an axial hollow reduced portion 35 that is journaled in the central portion of the ?tting 20 and also provided with peripheral packing rings. At the right end, as viewed in Figure '1, the valve I9 has an axial intake passage 35 and a. second longi tudinal passage 31 at one side ofv said passage ' ?red in the chamber 21 and the port 4I simul taneously registers with passage 42 so as to per mit the expanding gases to pass from the com bustion chamber into the chamber I5 of the housing behind the succeeding vane I1 for driv ing the piston I12. As the piston continues to ro tate, the valve I9 will have its port 39 registered with the passage 45, thereby permitting the spent gases to pass from the housing chamber I5 and 36. The inner end of passage 36 communicates 10 outwardly through the exhaust pipe 26 by way of passage 31 and chamber 23. The ports of the with a peripheral arcuate port 33 provided in valve are in overlapping relation, as shown, so the valve I9 adjacent the combustion chamber that when a charge is admitted for compression 21, while the inner end of passage 31 communi in advance of. one vane, spent exhaust gases are cates with another peripheral arcuate port 39 of the valve I9.

In this way a constant elec bustion chamber, and a driving connection be trical connection is provided between the wire tween the piston and said Valve, said valve hav 49 and the feed terminal of the spark plug, while ing two longitudinal :passages in an end portion allowing the spark plug and valve‘ to rotate in the thereof, each communicating at its inner end operation of the engine , As the piston I2 rotates, the valve I9 is driven so as to register port 38 with passage 44 and ad mit an explosive charge to the housing chamber I5 in advance of one of the vanes I1 of the en gine. Continued rotation of piston I2 causes the explosive charge to be compressed, whereupon the valve I9 will have turned to a position wherein the port 40 has registered with the passage 43 for admitting the compressed charge from the housing chamber I5 to the combustion chamber 21. The compressed charge is then immediately with a di?ferent ‘port of the valve, a ?tting se cured to the head and including a central intake passage communicating with one passage of the valve-and a surrounding exhaust chamber com municating with the other passage of the valve, a charge supplying pipe coupled to the ?tting in communication with the ?rst-named passage of .65 the latter, and an exhaust pipe leading from the exhaust chamber of said ?tting.
