Definitions
- This invention relates to orbital type motors that do not function with aid of vanes, and can be operated as any type of internal combustion engine,hydraulic motor,or compressor.
- Background Art In previous constructions involving circular pistons orbiting in a cylindrical cavity,a common problem has found.
- the cavities can be in any configuration, it is with them set round a cylindrical housing so that, then the cylinder next in order of firing can be used to scoure and recharge the preceeding cylinder;that the engine shows to best advantage.
- a circular housing excentrically supported round a shaft that is in turn supported centrally and rotatably in an enclosing casing, said housing able to describe an orbital path within the casing on rotation of the shaft relative to the casing.
- Cylindrical cavities are journalled equally spaced round the peripheral surface of the housing to a required depth,and sections of the same radius as the housing,are made integral with the housing such as to enclose the cavities.
- Pistons are slidably fitted in the cylindrical cavities, and conected by rods journalled slidably through the inward face of the cavity; to members excentrically supported on a cylindrical bush round the common shaft, rods being pinned to said members. Said members able to orbit within the housing by reason of clearance provided within the housing.
- the excentric members are set with the maximum throw oposite to the excentrics on which the cylinder housing orbits, and as a consequence, the bush on which the piston excentrics are supported will be caused to orbit in the oposite direction,gearing means are provided between the bush and the shaft to guide the piston excentrics in said oposite direction.
- the conecting rods will there-fore be able to remain slidably supported in the housing while driving the piston.
- a further advantage of contra-rotation is that only half the throw of the excentrics is required,with a resulting saving in the Disclosure continued peripheral speed of the members.
- While the cylinders of the engine can be in any configuration provided they are caused to orbit, the method of spacing them radially round a circular housing has the advantage of permitting each cylinder next in order, to charge the preceeding cylinder as it completes its inward stroke.
- Cylinder valves slidably fitted in channels communicating the two adjoining cavities,regulate the induction and transfer of said charges from the inward side of the advance piston to the cavity outward of the preceeding piston
- valves will be drawn inward during the outward movement of the piston,uncovering a port and permitting a charge to be inducted inward of the pistons.
- the inducted charge is brought under pressure and said pressure drives the valve outwards sealing off the induction port and uncovering one communicating to the preceeding cavity, scouring and re-charging said cavity as it begins its outward stroke.
- contacts set in the side wall would complete a circuit to the ignition device at the correct time.
- the usual jacket round the cylinders can be supplied through the stablizing excentrics placed between housing and side wall Lubrication
- Fig. (1) is a view of the engine with the side casing and adjacent excentric. member (10) removed. Shown are the circular housing (2)in which the cylindrical cavities are journalled.Slidably fitted in the cavities are the pistons (3)conected to the orbiting members on excentric(4)by rod (5 ) beingjournalled through the inner surface of the cavities.
- the freely rotatable bush (6) supports the excentric members which drive the piston to vary the combustion cavity (8)and the induction cavity (9)which are communicated by channels (16) between adjoining cylinders.
- the cylinder housing is caused to orbit by excentrics (10)and is linked to the piston excentrics by reverse gearing (7)driving the bush (6)off shaft (15)
- the combustion cavity (8) recieves injected fuel through ports (11) and is exhausted thruugh port (14)when it communicates with port (12)
- the induction cavity (9) is charged through channels (16)(not shown)

Abstract
Un bloc cylindre (2) radial tourillonné excentriquement sur un arbre (15) est contraint de suivre un mouvement orbital à l'intérieur d'un carter stationnaire (1) par des excentriques stabilisateurs (non illustrés) placés entre le bloc cylindre (2) et le carter (1). Les pistons opposés (3) placés à l'intérieur des cylindres sont reliés entre eux de manière rigide et montés excentriquement sur un manchon (6) pivotant autour de l'arbre (15). Les bielles (5) de connexion des pistons sont soutenues de manière coulissante dans des manchons de guidage au niveau de l'extrémité intérieurre des cylindres. Un agencement d'engrenages (7) aménagé entre le manchon (6) et l'arbre (15) assure la rotation de l'arbre (15), le mouvement orbital du bloc cylindre (2) qui en résulte à travers ces excentriques (10) étant accompagné par une contre-rotation dudit manchon (6) et des excentriques (4) des pistons, d'où il s'ensuit un mouvement de va-et-vient relatif des pistons (3) à l'intérieur des cylindres avec des vitesses absolues réduites des parties mobiles. La présente invention se rapporte en particulier à un moteur à deux temps présentant un transfert de charge entre les cylindres et comprenant des lumières d'échappement (14) aménagées dans les parois des cylindres qui s'alignent périodiquement avec des lumières (12) correspondantes aménagées dans le carter (1).
