ROTARY INTERNAL-,(ZOMBUSTION ENGINE.
Specification of Letters Patent.
. Patented Apr. tat, 15nd.
Application filed February 12, 1912. Serial No. 677,101.
To all 2071 0172, it mag ponccrn Be it known that I, GUJLLAUME Bonner, a citizen of the Republic of France, residing at 18 Rue Pierre-Levee, Paris, in the Republic of France, have invented certain new and useful Improvements in Rotary Internal-Combustion Engines, of which the following is a specification.
My present invention relates to rotary internal combustion engines, in which the fly wheel maybe directly connected to the shaft supporting the rotor receiving the'impulses ofithe explosion.
The principal object of my invention is to provide an equally balanced engine, simple in construction, efiicient in action and inexpensive to manufacture.
Further objects pf my invention are to avoid the 11% of reciprocating valves and spring actuated members; to provide a compact structure; to provide an engine with an inlet stroke interior to the expansion stroke, so that the waste products of combustion escape only after the maximum power of the explosion has beenutilized; and, to provide a hlgh speed engine with smooth and silent runnmg qualities.
Other objects of my invention will appear in the specification, in connection with the accompanying drawings, forming a part thereof, in which: 4 Figure 1 is a central section through the engine at a plane coincident to the axis of the main shaft thereof, and passing through one of the drum valves, only that portion of the mechanism above the said axis being shown, it being understood that the mechanism is duplicated below the horizontal plane coincident with said axis. Fig. 2 is a view similar to Fig. 1, hut in a plane at right angles to the axis of the main drive shaft of the engine.
In the drawings, where similar'charact-ers refer to similar parts in both views, 6 designates the main drive shaft which has keyed 1 thereto, in any suitablemanner, a disk rotor a, and fly wheel f, the shaft being supported by a casing 7c. It is desirable that the bearings between the shaft 0 and casing in include ball bearings m to facilitate rotation of the shaft, such balls being confined to a predetermined path of movement in any suitable manner, preferably so that the position of the rotormay be adjusted with respect to the casing into an annular "cavity k. of which, its periphery extends. Packprovided with a plurality of peripheral teeth 0 and a: provided with yieldable' packings o and a2, respectively, set in the crowns of said teeth, to contact with the inner wall of said cavity is during rotation of the to tor with respect to the casing is. An inlet port drum valve 1' is carried within a cavity w in said casing, open to the cavity iv and is provided with peripheral recesses r adapted to accommodate any of the teeth of the rotor a, and also to peripherally cont-act with the rotor to divide the cavity is into conduits t and a. This valve 7 contacts with a curved wall to of said cavity 20, said wall to being intermediate an inlet port 2) for combustible fluid and the cavityk of the rotor casing. A by-pass s is provided in said walls to that the relative curved linear dimension of the wall with respect to the peripheral openings of either recesses r is such that the valve 1', in rotating, at predetermined pe riods provides a communication between the port a and cavity is. An outlet port 3 in communication with cavity k at the opposite side of valve r from inlet port a is open to the conduit u provided by the teeth of the roller and the contact of the valve with the periphery of the rotor.
Spaced apart from cavity to is a second cavity 9 adapted to accommodate a compression control drum valve b, substantially like valve 7*, in that it is provided with peripheral recesses 5' adapted to accommodate any of the teeth of the rotor, and to peripherally contact with said rotor to divide the cavity 70' into conduits t and u. The valve :3) peripherally contacts with wall portions g and g" of the cavity 9, the curved linear dimension of said Walls 9' and g" being such that cavity 6 at predetermined periods provides communication between the conduits t and the cavity g and the cavity (1 and the conduit u.] T 0 provide a fluid tight contact between the periphery of the valves and the several elements they contact with, I may find it desirable to pro vide yieldable packing strips 2 disposed crosswise the periphery of the valves and carried thereby. A port 12 in casing k communicates with the conduit u and the end .of a spark plug p adapted to ignite the charge introduced into said conduit u. The rotor and valves rotate in the directions indicated by arrows, and it will be noted'that the recesses b of the valve 1) pass the conduit u in advance of the port p.
The valves 1) and 1" are mounted upon "shafts s, the shafts, as indicated in Fig. 1 of the drawing, carrying a crank 71 operatively connected to a reciprocable and oscillatable member h. The fly wheel f is provided with a cam groove 9 into which a rotor carried by member is rides. By this construction, the drum valves are driven at. a positive ratio with respect to the-rotor a, that is, so that the teeth of the rotor are successively accommodated by alternate re cesses of the valves. The disposition of parts are such that member 72. is carried over its dead centers, by the engagement of the rotor teeth with the recesses of its respective valve, so that there is positive movement provided fer throughout the working of the engine. To facilitate assemblage of the valves, in place, they ma be keyed to then-respective shafts s as indicated at 7' and such cavities Z, of the casing is. may be utilized for cooling the engine by the introduction of fluid thereinto, in the well known manner. It is to be noted that the rotor a carries vanes n extending laterally of the rotor in the space comprehended by the outer edges of the cavity is, these vanes facilitating cooling of the engine when working.
The operation of the engine is as follows Assuming that the relative disposition of parts are such as shown in Fig. '2 of the drawing, upon rotation of the rotor a as soon as tooth a: has passed by-pass s, the re cess r in valve 1' forms communication with cavity is and inlet port '0, the periphery of the valve r contacting with the periphery of the rotors preventing egress of the combustible fluid to the outlet port y, a charge is drawn within conduit 2?. As the rotor moves on in the direction indicated by the arrow, the tooth ac approaches the valve 6, the recess b of the valve forms a communication with cavity 9 and conduit t, past walls g.
' rotation of the parts p'ermitsthe same recess b to afford communication past wall 9' between compression cavity 9 and the conduit 9', as soon as the tooth w has passed the port 12 communicating with the spark plug. The charge is thus drawn into conduit u, inasmuch as the periphery of the valve 6 contacts with the periphery of rotor at, preventing egress of fluid to the conduit t. -Any ,time after the recess 1) closes communication between cavity q and conduit u the sparkmay be emitted and the charge exploded, the impact of which impinges the tooth :r forcing the rotor in the direction-indicated by the arrow. It is to be understood that an outlet port similarto that designated at y is in communication corresponding number of teeth provided on the rotor to cooperate with said valves, to successively or simultaneously act to impart movement to the rotor.
I claim:
In a rotary internal combustion engine, the combination of a casing provided with a rotor cavity, cavities for accommodating an inlet port drum valve and a compression controlled drum valve, a rotary disk mounted on a concentric shaft and rovided with teeth forming pistons divid ng said vided with a'plurality of peripheral cavities and segments, said valve cavities being equal in number to the number'of teeth for regulating the admission of the explosive "mixture, cranks keyed to the axles of the rotary valves for actuating said valves at a rotor cavity into conduits, rotary valves pro- In testimon whereof I afiix my signature H. C. Coxn.
