Definitions

  • a rotary internal combustion engine is recognised as being superior in many aspects to a reciprocating internal combustion engine. Particular advantages are generally considered to be fewer moving parts and consequently less manufacturing costs and better reliability. In addition rotary engines do not generate much vibration which is an inherent problem with reciprocating engines.
  • a rotary engine generally includes a stator, the interior of which is substantially cylindrical to form a chamber and a rotor, the periphery of which is shaped so that as the rotor rotates within the stator, it will provide the necessary induction, compression, combustion and exhaust phases.
  • a continuing difficulty with rotary engines lies in excessive wear in the sealing between the periphery of the rotor and the wall of the chamber of the stator.
  • Another known problem with rotary engines is that the thermal efficiency of known rotary engines is usually inferior to that of reciprocating engines resulting in undesirably high fuel consumption.
  • stator having a substantially circular interior chamber with a rotor formed to rotate within the chamber, the rotor being provided with one or more radially sliding vanes, the tips of which seal against the wall of the chamber.
  • US Patent specification 4414938 also describes a rotary internal combustion engine which utilises a vane.
  • the engine has a stator having a bore with part of the wall of the bore being in cross sectional shape a part of a circle. The remainder of the wall is of an elliptical shape having a constant diameter through the centre of the circular cross-sectional shape.
  • the rotor is coaxially closely in contact with the circular shaped part of the wall and the vane has a dimension which is equal to the constant diameter.
  • US Patent specification 4515123 (Taylor) includes a power rotor which rotates within a bore of a stator housing.
  • the rotor has spring-loaded sliding vanes seated in radial slots in a manner that the tips of the vanes will seal against the bore of the stator.
  • a rotary transfer valve has a number of pockets in its surface and is in sealing contact with the interior surface of the cylindrical cavity.
  • a cam wheel is connected to the main rotating shaft and will intermittently rotate the transfer valve to transfer compressed gases from the leading side of the vane to the trailing side of the vane.
  • US Patent specification 5352295 also discloses a rotary engine which utilises a single vane and an eccentric rotor housed within a circular bore of a chamber of a stator.
  • the engine uses two substantially identical sets, one being a compressing portion and the other being a working portion, with the compressing portion and the working portion sharing a common output shaft.
  • the combustible gas is compressed in the compressing portion and is then transferred into the working portion where it is ignited and then exhausted.
  • the vane is secured to the output shaft and extends through the rotor with the tip of the vane sealing against the bore of the chamber.
  • US Patent specification 5415141 discloses a rotary engine in which the bore of the stator is elliptical.
  • the rotor which is mounted on a shaft which extends through the axial centre of the bore, has a circular periphery.
  • the rotor includes a number of radial vanes which extend through the rotor in a manner that the tips of the vanes will seal against the bore of the stator.
  • the side-wall of the stator is formed by an elliptical plate which has an elliptical groove similar in shape but smaller than the elliptical bore.
  • a number of radial slots are formed in the rotor to receive vanes which are provided with pins which engage within the elliptical grooves in the side plate. As the rotor rotates, the pins of the vanes will follow the grooves and thereby cause the vanes to reciprocate within the slots to maintain the tips of the vanes in contact with the bore of the stator.
  • one form of the invention comprises a rotary engine having separate induction/compression and combustion/exhaust units, each unit comprising a substantially identical stator having a bore into which an inlet port and an exhaust port communicate.
  • each stator housing a rotor which has a circular peripheral surface, the rotor being adapted to have rotatory movement within the bore by being connected to a common drive shaft journalled in bearings supported by the stators,
  • the surface of the bore of the stator is in the shape of a first and a second arc having separate axes with at least the first arc being part of a circle and wherein the peripheral surface of each rotor is closely spaced from the wall of the bore formed by said first arc,
  • each rotor being provided with at least one vane which has a radial reciprocating movement guided within a slot formed in the rotor in a manner that as the rotor rotates, the vane will reciprocate in the rotor to maintain a sealing portion of the vane in sealing contact with the surface of the bore of the stator.
  • the reciprocating movement of the vane is controlled by control means to maintain the tip of the vane in sealing contact against surface of the second arc of the bore of the stator during rotatory movement of the rotor.
  • control means comprises a continuous groove formed in at least one side wall of the stator with the shape of the groove complementing the shape of the said second arc and wherein the vane includes means to cooperate with the continuous groove to positively control the reciprocal movement of the vane within the slot of the rotor.
  • a pin projects from the vane and engages within the groove to positively control the reciprocal movement of the vane during rotation of the rotor.
  • the vane includes: a vane carriage adapted to reciprocate within the slot formed in the rotor, an outwardly extending groove the major axis of which is radial to the drive shaft formed in each side edge of the vane carriage and a groove formed in the tip of the vane carriage to extend between the grooves formed in the sides of the vane carriage spacer members located in the side grooves of the vane carriage and a seal insert located within the groove in the tip of the vane carriage a compression spring comprising two spaced apart parallel legs joined by a bridge portion, the legs of the spring being located in the side grooves of the vane carriage between the spacer members and the root of the groove and the bridge of the spring being located in the groove in the tip of the carriage between the seal insert and the root of the groove, the construction and arrangement being that the spring will exert outward compressive forces to maintain the spacer members and the seal insert in sealing contact with the bore of the stator.
  • the surface of the wall of the bore of the stator is shaped into a curve.
  • the shape of the curve is generated by an arc having a radial centre on a notional circle concentric with the drive shaft.
  • each vane includes a resilient sealing means shaped to complement the curve of the wall of the bore of the stator, means being provided to maintain a sealing surface of the vane in contact with the curved surface of the bore of the stator.
  • Figure 1 is general diagrammatic view of the exterior of an engine constructed according to the present invention.
  • Figure 2 is a side elevational diagrammatic view of the exterior of one preferred form of an engine constructed according to this invention.
  • Figures 3a, 3b, 3c and 3d are sectional views along the line A- A of Figure 2 of the interior of the induction/compression section illustrating the positions adopted by the rotor for the various phases during the rotation of the rotor.
  • Figures 4a, 4b, 4c and 4d are sectional views along the line B - B of Figure 2 of the interior of the combustion/exhaust section illustrating the positions adopted by the rotor during the various phases of the combustion/exhaust.
  • Figure 5 is a sectional view through a part of the stator and the rotor illustrating one method of effecting reciprocal movement of the vanes.
  • Figure 6 is a sectional view along the line VI - VI of Figure 2.
  • Figure 7 an exploded view of the component parts of one preferred form of a vane.
  • Figure 8 is a cross sectional view similar to that of Figure 5 illustrating a modification of the construction of the engine.
  • Figure 9 is a cross sectional view similar to that of Figure 6 but of the modification illustrated in Figure 8.
  • the engine comprises an induction/compression section 1 and a combustion/exhaust section 2.
  • Each section comprises a stator and the induction/compression section includes inlet port 3 and an exhaust transfer port 4.
  • the combustion/exhaust section 2 includes an inlet transfer port 5 and an exhaust port 6.
  • the exhaust transfer port 4 of the section 1 is connected by piping 7 to the inlet transfer port 5 of the second section 2.
  • Valve means 8 is positioned in the piping to allow compressed gases to be transferred from the section 1 to the section 2 at the required intervals and to prevent the back flow of gases from the section 2 into the section 1.
  • One such valve means is illustrated in Figure 4. In this illustration the valve means 8 is located within the inlet port and can consist of a rotary valve 10 such as that illustrated.
  • the valve 10 can be connected through suitable gearing such as that illustrated diagrammatically at 9 or by other known means to the drive shaft 15 so the timing of the opening and closing of the valve 10 will be positively controlled. Although in the illustration a rotary valve is depicted to time and effect the entry of combustible gases 12 from the section 1 to the section 2, it is to be understood that any other suitable valve mechanism and valve timing apparatus can be utilised for this purpose.
  • the bore of the stator is in the shape of two arcs of a circle with the axis of the radius forming the part of the arc 20 being offset from the axis of the radius forming the arc 21.
  • the drive shaft 15 is journalled in bearings (not shown in the drawings) which are located in end plates 40 of the stator. The axial centre of the bearings and therefore of the drive shaft 15 equates to the axial centre of the portion forming the arc 21 of the bore.
  • a rotor 25 is appropriately fixed to the drive shaft 15 so that rotation of the rotor will rotate the drive shaft 15.
  • the periphery 26 of the rotor 25 is circular and as can be seen from the drawings, the periphery 26 will lie closely adjacent to the surface of the arc 21 but does not contact the surface. Consequently as the rotor 25 rotates, the periphery 26 will maintain a constant distance from the surface of the arc 21.
  • the rotor 25 includes radial slots 30 and in the drawings two such slots 30 are illustrated.
  • Each slot houses a vane 31 which can have radial reciprocating movement within the slot.
  • the vane can be composed of a suitable material that will provide minimum friction between the side wall of the vane and the interior of the slot 30 and which will not be adversely affected by the combustible gases, the combustion process or the heat graduations imposed on it during an operating cycle.
  • Each vane has a tip 32 composed of a material that will form an effective gas seal against the bore of the stator and provide a satisfactory service life as will be described in greater detail later.
  • Each vane is provided with a pin 35, the axis of which is substantially parallel to the axis of the shaft 15 and extends out the end face 33 of the rotor 25.
  • the stator is provided with end plates 40, each of which has a cavity to receive a cam plate 41 which has a continuous groove 42, the axis of which corresponds to the axis of the arc 20 of the bore of the stator.
  • the groove 42 is of a width and depth that the end of the pin 35 can engage within the groove as a neat but sliding fit.
  • each end plate 40 of the stator includes the cam plate 41 and groove 42.
  • the cam plate is preferably located in the end plate 40 by means of locating pins which register within locating holes 43 formed in the face of the end wall of the stator.
  • the purpose of the locating pins is to allow the cam plate 41 to be manually rotated so the timing of the movement of the vanes can be altered as required by rotating the cam plate in relation to the end plate 40.
  • the locating pins are fixed within the locating holes 43 to prevent movement of the cam plate 41 until further adjustment is required.
  • FIG. 7 illustrates an alternative form of vane suitable for use with the rotor of the present invention.
  • a vane carriage 50 comprises a solid billet of essentially rectangular shape and is provided with pins 54 which project from the sides of the vane carriage and which correspond with and replace the pins 35 previously described in relation to Figures 3, 4 and 5.
  • Each vane carriage is of a size that it can be engaged within a slot 30 in the rotor 25 as a neat but sliding fit.
  • a groove 51 is formed in the sides 52 and end 53 of the vane carriage 50 and a tension spring 55 is located in the groove.
  • the spring 55 includes arms 56 that are splayed as indicated.
  • Spacer members 58 are provided which can fit within the grooves on the sides of the vane carriage with the base of the spacer members contacting the splayed portions of the spring 55.
  • the distal end of each spacer member is preferably bevelled as illustrated so it can contact an equivalently bevelled end 60 of a seal insert 61.
  • the seal insert 61 is preferably formed of a suitable sealing material so the sealing face 62 can seal against the interior of the bore of the stator and provide a gas seal during rotation of the rotor within the stator.
  • the spacer members 58 and the seal insert 6 lean be formed of a single piece of material or they can be formed of two or more laminate sections.
  • the seal insert 61 includes an anchor hole 63 so that after the seal insert 61, the spacer members and the spring 55 have been located within the groove 51, the assembled vane can be retained within the vane carriage 50 by passing an anchor pin 64 through the hole 65 formed in the vane carriage 50 and through the anchor hole 63.
  • the diameter of the anchor hole 63 is greater than the diameter of the anchor pin to allow a limited movement of the seal insert 63 in relation to the remainder of the assembly of the van carriage 50.
  • the spring 55 is so shaped that it will exert a tension on the reverse face of the seal insert 61 to assist in maintaining contact between the seal and the wall of the bore of the stator. The movement of the seal is limited by the size of the anchor hole 63 in relation to the anchor pin 64.
  • sealing means is also provided between the sides of the rotor and the end plates of the stator.
  • suitable sealing devices as will be apparent to those skilled in this particular art can be utilised.

  • the stator 84 is fixed to the drive shaft 85 journalled in the walls of the stator by suitable bearings (not shown in the drawings).
  • the surface of the wall of the bore is curved as illustrated. The shape of the curve can be generated by a radius struck from a notional circle concentric with the drive shaft 15.
  • the curve is semi-circular but it will be understood other geometrical shapes can be utilised.
  • the stator includes radially extending slots 86 and a vane carriage 87 is housed in each slot so it will have reciprocal sliding movement within the slot.
  • the vane carriage has a curved sealing edge, the shape of which complements the shape of the curved surface of the bore of the stator.
  • the outer surface of each vane carriage is shaped to receive a tensioned sealing member 88 which may consist of a plurality of separate members as illustrated although the nature of the sealing member can be varied as required for the particular circumstances.
  • the outer surface of the sealing members will provide a gas seal against the surface of the bore of the stator.
  • the vane carriage also include means to positively reciprocate the vanes within the slots.
  • the vane carriages can be provided with pins such as those illustrated at 54 in Figure 6 which can engage within grooves 42 (see Figure 6) formed in the sides walls of the stator.
  • the sealing means are formed of a resilient material which can continue to provide an outwardly extending tension to form a gas seal against the wall of the stator.
  • the material forming the seals will be such that the seals are able to resist the effects of erosion, temperature and other forces that will be imposed on the seals in the environment.

Abstract

Cette invention concerne un moteur rotatif à ailettes comprenant des stators (1, 2) globalement identiques et distincts qui sont reliés par un arbre d'entraînement (15) commun. L'un des stators (1) représente l'étage d'induction/compression, tandis que le second (2) représente l'étage combustion/échappement. Un rotor (25) possédant une périphérie circulaire (26) vient se loger dans l'alésage de chaque stator (1, 2) grâce à l'arbre d'entraînement (15) commun. Les alésages de chaque stator se présentent sous forme d'un premier et d'un second arcs (21, 20) qui possèdent chacun un axe distinct. Le rotor (25) est disposé dans l'alésage et sur l'arbre d'entraînement (15) de manière à ce que sa surface périphérique (26) se trouve à proximité immédiate du premier arc (21). Au moins une ailette (31) va effectuer un mouvement de va-et-vient par coulissement dans une fente radiale (30) pratiquée dans le stator. Chaque ailette (31) comporte une broche (35) qui pénètre dans une gorge (42) pratiquée dans la paroi d'extrémité (41) de l'alésage. Cette gorge (42) possède un axe qui correspond à l'axe du second arc (20). Lorsque le rotor (25) entre en rotation, la pénétration de la broche (35) dans la gorge (42) va faire aller et venir l'ailette (31) de manière radiale dans la fente (30) du rotor (25), ceci de manière à conserver un contact hermétique entre la pointe de l'ailette et la paroi de l'alésage du stator (1, 2).
