Definitions

  • This invention relates to a rotary internal combustion engine that operates using simple and continuous unidirectional rotation about a fixed axis.
  • 5 opposed ball assemblies are carried by a rotating rotor disc, rotating about its axis inside a housing that contains two rotating valves which are interconnected to the rotor disc by a gear train.
  • valve assemblies In order to permit continuous rotation of the rotor disc, there must be configuration which allows for transfer of the air-fuel mixture compressed in front of the ball assembly to a combustion chamber immediately behind the same said ball assembly momentarily prior to combustion occurring.
  • One of the rotating valves is arranged to provide this novel feature of the invention.
  • the valve assemblies In order to reduce friction, the valve assemblies rotate and roll in contact with the rotor disc, both surfaces are at the same speed at point of contact.
  • the ball assemblies rotate so as to roll along the inner surface of the housing with reduced friction.
  • FIG 1 is a sectional elevation of the rotary internal combustion engine through a plane common to the ball assemblies and both rotating valves in accordance with the present invention.
  • FIG 2 is a general sectional elevation as depicted by Section in FIG 1.
  • FIG 3 diagram of ball assembly movement to full compression air-fuel mixture transfer, combustion and expansion.
  • one configuration of the invention comprises an outer housing 1 , 2 is a space between the outer housing and the rotor disc 3 which supports the ball assemblies 5.
  • the rotor disc 3 is supported on bearings 20 with a shaft extension carrying gear wheel 18 and a shaft extension for the power take-off.
  • the two rotating valves are numbered 4, and are supported on bearings 17 and are driven by pinion gears 19 mounted on the shaft extensions and meshing with gear wheel 18.
  • a spring assembly 6 acts on a support 7 to hold the rotating balls 5 in rolling contact with the contoured track of the outer housing 1.
  • a passageway 8 conveys the compressed air-fuel mixture in 2 to the combustion chamber 9. 10 is a spark to initiate combustion and expansion of the gases.
  • the air plus fuel charge is induced into the space 2 FIG 2 as the rolling ball assembly 5 moves past entry port 11 to full compression at position 1 FIG 3, thus ensuring a continuous charge for the cycle. Due to movement of ball assembly 5, the pressure in the space 2 is reduced to below atmospheric pressure, ensuring flow through the induction system 14.
  • ball assembly 5 drives the expended gases ahead, expelling them through port 12 in direction 13. Both ports 11 and 12 are open, with no valving required.
  • the desired compression ratio can be obtained by designing the volume of passageways 8 and 9 and volume ahead of ball assembly 5 prior to the opening of transfer port in rotating valve 4 position 1 FIG 3.
  • the labyrinth seals 22 FIG 1 and FIG 4 act as an interface, preventing the compressed combustion charge and products of combustion flowing in the opposite direction to the centrifugal force generated by the rotor disc's revolutions.
  • the faces between the rotating rotor disc 3 and outer housing 1 and cover 15 are provided with oil lubrication by arranging leakage through bearings 20, 21 is a double lip seal to prevent ingress of contaminates and leakage of oil.
  • the same principle is applied to valve 4 by oil leakage from bearings 17. All bearings are high speed oil lubricated.
  • Bearings 17 are of the hydrostatic type to support the load necessary to keep valves 4 and rotor disc 3 in rolling surface contact.
  • the periphery of the unit can be arranged with a suitable jacketed area for use of a suitable cooling fluid to carry away surplus heat.
  • the preferred form of the invention has many arrangements, for example, it can be arranged with three rotor disc assemblies spaced one hundred and twenty degrees, resulting in a continuous smooth power and torque output. Further, the first rotating disc assembly with the rotating valves modified to transfer the compressed fuel-air mixture to a second rotating disc assembly, resulting in an arrangement with continuous power output and smooth balanced running.
  • the inventive novel engine can also be used as a pump, suitable for handling any compressible medium.
  • the engine can be used as a hydraulic pump or motor, and/or for pumping any fluid.

Abstract

Cette invention concerne un moteur rotatif à combustion interne qui est soumis à une rotation unidirectionnelle continue autour d'un axe fixe. Ledit moteur comporte au moins deux ensembles à billes (5, 7, 6) diamétralement opposés portés par un disque rotor (3), des soupapes rotatives (4) reliées au disque rotor par un train d'engrenages, l'une de ces soupapes rotatives (4) étant conçue pour permettre le transfert du mélange air-carburant à l'avant de la bille (5) à travers un passage (8), avant la combustion qui se produit en deux phases à chaque révolution du disque rotor (3), et un logement (1) muni d'un orifice d'entrée (11) permettant l'entrée de l'air ou du mélange air/carburant (14) et d'un orifice de sortie (12) permettant l'évacuation des gaz d'échappement (13).
