Definitions

  • My invention relates to improvements in internal combustion engines and .more particularly in engines of the type comprising a plurality of oppositely moving pistons having a common'combustion chamber and each acting on a crank shaft, the said crank shafts being provided with additional cranks connected with each other by a frame insur-k ing rotation of all the cranks in onedirection.
  • the framev provides apart of a rotary pump the stationaryV member of which is ixed to or made integral with the frame of the engine.
  • the suction or pressure chamber provided by a member connected to orrmade integral ⁇ with the machine frame may be disposed internally ofthe lcoupling frame or externally thereof.

  • Fig. 4 is a sectional elevation taken on line ⁇ j In Figs. land 2 I have shown a two-stroke f cycle internal Acombustion engine. But I wish it to be understood that my invention is not limited to Athis type of engines. As shown the engine comprises .three cylinders 1a, 1b, 10 disposed radially of oneanother within a 'casing 2 and yhaving ⁇ a common combustion chamber 4. Withinthe'cylindersthere are three pistons 3 connected by crank shafts 5 with-crank pins 6a, 6b, 60 of crank shafts 7c, .7c mounted in the casing 2; VThe cylinders 1b, 1c are provided with intakeor scavengingv ports 8 andthe cylinder lawith exhaust ports'9. The pistons are displaced relatively to each other so1 that thepi'stons hind the piston within the cylinder 1a,.so thatin-the operation ofthe engine at first the exhaust ports and thereafter thev scavengling ports are opened. v
  • crank shafts 7&70 and 7c are provided each with an additional crankghaving crank pins 11a, '11b and llc disposed parallel to each' other and positive- 75 Y of the cylindersl'b and 1c slightlyv -lag bess, ly connected with each other by ak rigid frame 35 sotha't they .rotate .inthe same di-V rection; Therefore 'they forcesl of the crank f shaftsconnected with the pistons are uniformly transmitted to the shaft v11a byV which -the power ofthe engine is transmitted to a 'i driven member.
  • the coupling frame is provided at its f .middle .With a largev recess providing the innerchamber of a cylinder 36,*thesaid cylindertightly bearing withone end face on lo the wall 10 of the machine frame and with the other end face on a head 37.
  • a .cylindrical hollow body 38 is eccentrically mounted, which is secured by means of screws 39 to the wall l0 of the machine frame.
  • the hollow chamber of the cylindrical body 38 is subdivided by a hollow partition 40 into two chambers 4l and 42, and within the said hollow partition 40 a slide 43 has reciprocating movement, which is connected by a cylindrical head 44 with a shoe 45 adapted to .slide on the innersurface of the cylinder 36, springs 46 being provided for pressing the shoe into engagement withthe wall of the cylinder 36.
  • the cylinder 36 is divided intotwo chambers 47 and 48, and the chamber 48 communicates with the chamber 42of the cylindrical body 38 through a passage 49, and the chamber 47 communicates through a passage 50 with the chamber 4l of the said body.
  • the cylinder 36, the cylindrical body 38 andthe slide 43 provide a rotary engine which is operated by the cylinder 36being rotated by means of the frame 35, and which is formed with a crescent-shaped compression chamber.
  • the chamber 4l of the stationary body 38. communicates through a tubular stud 5l with the outer air and provides the suction chamber ofthe pump, while the chamber 42 acts as a pressure chamber and communicates with-the inner space 52 of the machine casing 2, thesaid machine casing being closed tightly as against the outer air;
  • the inner space 52 is adaptedto communicate with thecombustion chamber y4 through the scavenging or intake ports 8 mad-e inthecylinders 1b and lc... ⁇
  • the pump 36, 38 for scavenging is confined within the frame 35 so that separate room is not needed for the said pump.
  • the frame 35 acts as a driving member and it provides a component part of therotary engine.
  • the suction and .pressure chamber can be mad-e comparatively large, so that a large volume of air is .supplied with small air velocities. Thereby a noiseless operation of the pump is insured.
  • a rectangular housing 53 is lprovided on the connecting frame 35, the interior of said housing beingdivided into two chambers 55 and 56 by means of a slide 54.
  • the slide 54 is so mounted in a guide 57 provided with openings 57, that it can take part in the upward and downward movement of the connecting frame 35, but not in the transverse movement of said connecting frame, upon the revolution of the latter about the crank pins, inthe direction of the arrow in Fig.- 5.
  • the guide 57 is secured to the frame 2 of the machine, and thereforedoes not partake of the movement of the connecting frame 35.
  • the slide 54- is perforated with four types of ports.
  • the ports 8O provide a connection of the chamber 56with an opening 8l of the machineelement 82..
  • the ports 83A ofthe slide 54 provide a ⁇ connection between an opening'l 84 connnunicating with the outer airfand the chamber 55.
  • the ports 85V may provide a connection to the outer air, or to theopemng 84, with the chamberg56, whereas the ports 86'serve for providing a communication between the'l chamber 55 and the opening 81er;
  • the yscavengingfair chamberl 52.4 The four pairs of ports 80, .83, 85and 86 are thus so controlled during the upward anddownward movement of the slide 54, by means the guides 54 or the openings 5T thereof," ⁇ that the outer air enters through the slide into the chamber 55 or 56, when these chambers 'are servingas' suction chambers.v ⁇ When these chambers areservmg as pressure chambers,
  • FIGs.V 3 and 4 I have shown a modification in which the hollow space of the frame 59 connecting the crank pins 11a, Il?) and 110 provides the pressure chamber 60 ,continu- ⁇ ously communicating through an opening 61 made in the wall 10 with the chamber 52 of. the-machine frame 2.
  • the frame 59 is guided 1 in an airtight manner between the end wall l0 and the head 62 secured to and spaced from the machine frame, and the space provided between the sanie and the head 62 is divided by partitions 63 into three chambers 64, 65
  • the head 62 is provided with openings 70 through which the sectional chambers 64, 65 and 66 are adapted to communicate within the outer air, the said openings being adapted to be closed by hinged gates or valves, 69.
  • the wall of the frame 59 is provided with openings 71 whichv are adapted to be closed by hinged gates or valves 72, and
  • the chamber 64 acts as a suction chamber, so that the valves 69 are opened and the valves 72 closed.
