- This invention relates to a rotary motor which may be operated on the internal combustion engine principle, but may also operate as a steam engine or hydraulic motor.
- vanes disposed radially to and spaced equally about the shaft axisand supported in the housing for reciprocal movement radially with respect to the shaft axis, said vanes being connected to the piston member so that the piston member can move relative to each vane in a direction at right'angles to the direction of reciprocation of the respective vane and at right angles to the shaft axis to permitorbiting of the piston member upon reciprocation of the vanes relative to the housing, sealing means operatively disposedbetween each vane and the piston member, the housing peripheral wall and the housing end walls todivide the cavity intoa plurality of chambers the volume of each chamber varying as the piston member orbits, and means to regulate the admission to and exhausting from each chamber insequence ofa working fluid to induce orbiting of the piston member and resultant rotation of the shaft.
- the orbital movement of the piston member within the cavity of the housing is such that the piston member maintains a constant angular relation to any diametral plane passing through the shaft axis.
- each vane may be slidably supported in respective radial slots in each end wall and peripheral wall of the cavity.
- an engine comprising a housing having a generally cylindrical cavity defined by a peripheral wall and opposed end walls, a shaft rotatably supported in the housing coaxial with the cavity, a piston member disposed within the cavity and journalled eccentrically on said shaft to describe an orbital path about the shaft axis when the shaft rotates, a plurality of vanes disposed radially to and spaced equally about the shaft axis, each vane being slidably supported in respective slots in each end wall and the peripheral wall for reciprocal movement radially with respect to the shaft axis, each vane being connected to the piston member to reciprocate relative to the housing upon orbiting of the piston member relative to the housing, sealing means operatively disposed between each vane and the piston member, the housing peripheral wall and as the piston member orbits, and means to regulate the admission to and exhausting from each chamber in sequence of a working fluid to induce orbiting of the piston member and resultant rotation of the shaft.
- the supporting of the vanes in the slots in the end walls of the chamber substantially reduces the stresses in the vanes, particularly when they are in their extended position, and thus the vanes will not bend or deflect, and may be made of a lighter construction with a resultant reduction in inertia loads.
- the surfaces of the vanes which are in wearing contact with the piston member or housing may be flat surfaces, and thus uniform wear on these surfaces does not interfere with their functioning.
- the flat surfaces also simplify seal construction as flat seal strips may be used.
- Lubrication and cooling of the vanes may be simply effected by an oil spray directed onto the face of the vanes when in the retracted position as substantially the whole surface of the vane is then outside the working chamber. Further, the incoming charge of gas will contact a large exposed surface of the vane as the vane is in its fully extended position.
- At least one member having two journalled sections eccentric with respect to one another. one rotatably supported in the housing and the other in the piston member with the axes thereof parallel to the shaft axis. the eccentricity of the journalled sections and the location thereof relative to the shaft being such as to guide the piston member in the orbital path when the shaft rotates.

- the chamber sections 18 have cavities 19 formed therein which constitute a cooling waterjacket.
- the arcuate length of the chamber sections 18 is such that when assembled slots 20 are provided between adjacent sections 18, the slots 20 extending the full axial and radial dimension of the sections and radially with respect to the crank shaft.
- the six chamber sections define an internal surface of generally hexagonal shape with the corners of the hexagon rounded by a curved surface which blends smoothly with the adjacent straight sides.
- each of the chamber sections 18 are two opposed chamber end plates .24, 25, of generally sector shape, which extend from the outer casing 10 to the vicinity of the crank shaft 16.
- the chamber end plates 24, also define between adjacent radial faces, radial slots 27 which register with the slots 20 defined by the chamber sections 18.
- the outer peripheral edge 28 of the chamber end plates are received in the recess 29 in the outer casing 10 and the end cover plates 11, 11a, chamber sections 18 and chamber end plates 24, 25, and held in assembly by the bolts 12 extending through aligned apertures therein and the locating dowels 31.

- the crank shaft 16 has the piston member 40 mounted on the eccentric journal 17 of the crank shaft through the bearings 21 to permit relative angular movement therebetween.
- the piston member 40 comprises the peripheral ring and integral side plate 42, and attached side plate 43, with six equally spaced slots in each side plate.
- the slots 45 in each side plate are arranged in the formation of a hexagon having an axis coincident with the axis of the eccentric journal 17 of the crank shaft.
- Corresponding slots 45 in the respective side plates 42, 43 are in alignment in the axial direction.
- the three eccentrics are supportedin bearing 52 in the inlet end cover plate 11 in equally spaced relation about the axis of the crank shaft and engage apertures 51 in side plate 43 of the piston member 40.
- the throw of the eccentrics 50 are arranged in relation to that of the crank shaft so that when the crank rotates the piston member describes an orbital path.
- the orbital path is such that the slots 45 retain a constant angular relation to any radial plane passing through the axis of the crank shaft 16.
- Annular seal rings 60 located in respective grooves 61 in each side plate of the piston member, are pressed against the chamber end plates by the respective spring strips below the seal rings.
- the crank shaft 16 is of two-piece construction whereby the web 21 and journal 22 may be detached from the eccentric journal 17 to permit assembly of the piston member 40 to the journal 17.
- the counterweight 32 has an integral cylindrical mounting portion 33 rotatably supported on the spigots 26 on the respective side plates of the piston member.
- the counterweight is disposed diametrically opposite the eccentric journal 17 of the crankshaft and is caused to rotate with the crankshaft by the pin 93 engaging the slot 94 in the counter-weight.

- the vanes are of generally rectangular shape and are supported in the slots 20 and 27 for sliding movement in the radial direction relative to the crank shaft 16.
- Each vane 70 is connected to the piston member 40 by two legs 72 extending along each radial edge of the vane and secured to the vane by studs 74.
- the laterally projecting pin 76 at the inner end of each leg is received in a slipper 92 which slidably engages the respective slots 45 in each side plate of the piston member so that the vanes reciprocate in response to orbital movement of the piston member 40.
- the seal strip 73 located in the recess 75 in the radially inner edge of the vane engages the outer peripheral surface 46 of the piston member.
- the spring strip 62 below the seal strip 73 maintains the latter in engagement with the peripheral surface 46.
- peripheral surface of the piston member 40 is thus of generally hexagonal shape with the corners rounded.
- Seal strips 77 and associated spring strip 78 are provided in radially extending grooves 79 in each side face of each vane, adjacent each end thereof.
- the seal strips 77 engage the walls of the radial slots 27 formed between the chamber end plates 24, 25.

- inlet ports 85 extend through the end cover plate 11 and the respective chamber end plates 24 to communicate with the respective chambers.
- the ports 85 are opened and closed by the piston member 40 during the orbital movement thereof.
- Similar exhaust ports 88 are provided in the opposite end cover plate 11a and chamber end plates 25, and are likewise opened and closed by the piston member 40. It will be noted the three of the inlet ports 85 are in the vincinity of the bearings 52 supporting the eccentrics 50.
- Each inlet port 85 communicates with the inlet manifold 90 and all exhaust ports 88 communicate with the exhaust manifold 91.
- This porting arrangement allows the engine to operate on the two stroke cycle, and the actual shape and location of the ports may be readily determined by those skilled in the art.
- a suitable blower (not shown) is provided-to deliver the mixture to the inlet manifold 90 communicating with each inlet port 85.
- the blower may be driven by the crank shaft 16 or may be an exhaust driven turbo blower.
- the fuel may be supplied by a conventional carburettor or a fuel ini jection system may be used. It' will be appreciated that the engine may also operate on the diesel principle, either'two or four stroke cycle.
- inlet and exhaust ports may be provided in the arcuate peripheral chamber section l8-with mechanically or other suitably operated valves to control the admission and exhaust of the charge to each chamber.
- a feature of this engine is that the rate of increase in volume of each chamber relative to the angular movement of the crank shaft is not uniform, the rate being initially high.
- the volume of each cylinder increases to approximately 68 percent of maximum volume during the initial 90 of rotation of the crank shaft from top dead centre. This results in a high torque at low engine revolutions.
- the engine shown in the drawings has provision for the fitment of conventional spark-plugs and these would be energised in sequence by a conventional magneto or coil and distributor ignition system. If the engine operated on the diesel principle, a suitable injector would be fitted to as a substitute for the spark-plug.
