Definitions

  • This invention relates to rotary piston and cylinder devices which may be, for example, in the form of an internal combustion engine, or a pump such as a supercharger or fluid pump, or as an expander such as a hydraulic motor or turbine replacement.
  • 'piston' is used herein in its widest sense to include, where the context admits, a partition capable of moving relative to a cylinder wall, and such partition need not generally be of substantial thickness in the direction of relative movement but can often be in the form of a blade.
  • a rotary piston and cylinder device comprises a rotor and a stator, the stator at least partially defining an annular cylinder space, the rotor comprising a rotor body and at least one piston fixedly depending from the rotor body and which is moved circumferentially through the annular cylinder space on rotation of the rotor relative to the stator, the rotor body being sealed relative to the stator, and a cylinder space shutter means which is capable of being moved relative to the stator to a closed position in which the shutter means partitions the annular cylinder space, and to an open position in which the shutter means permits passage of the at least one piston.
  • the shutter means presents a partition which extends substantially radially of the annular cylinder space.
  • the shutter means could be reciprocable, it is much preferred to avoid the use of reciprocating components, particularly when high speeds are required, and the shutter means is preferably at least one rotary shutter disc provided with at least one aperture which in the open condition of the shutter means is arranged to be positioned substantially in register with the circumferentially-extending bore of the annular cylinder space to permit passage of the at least one piston through the shutter disc.
  • the at least one aperture is provided radially in the shutter disc.
  • the rotor is adapted to receive the shutter disc.
  • the shutter disc passes through the cylinder space at least once.
  • the shutter disc is preferably driven from the rotor through a suitable transmission means.
  • the axis of rotation of the rotor is not parallel to the axis of rotation of the shutter disc.
  • the axis of rotation of the rotor is substantially orthogonal to the axis of rotation of the shutter disc.
  • the piston is so shaped that it will pass through an aperture in the moving shutter means, without balking, as the aperture passes through the annular cylinder space.
  • the rotor body comprises a hub, which may be part of a shaft, and the at least one piston extends generally radially outwardly from the hub, the stator extending coaxially around the hub to define the annular cylinder space which extends coaxially about the hub axis.
  • the rotor is in the form of a ring, and the at least one piston extends from the rotor ring into the annular cylinder space which is defined by the stator positioned internally of the ring (but it should be appreciated that the stator could have portions which extend generally radially outwardly beyond the ring if desired).
  • the at least one piston extends generally radially inwardly from the rotor ring.
  • the at least one piston may extend out from the rotor in a direction which is substantially parallel to the axis of rotation of the rotor, or at some other angle relative to the axis of rotation of the rotor.
  • the rotor body is preferably rotatably supported by the stator rather than relying on co-operation between the pistons and the cylinder walls to relatively position the rotor body and stator.
  • the hub is preferably journelled relative to the stator by suitable bearing means.
  • the rotor ring is preferably rotatably supported by suitable bearing means carried by the stator.
  • the annular cylinder space maybe divided into a plurality of annular cylinder spaces. Preferably there is at least one piston in each cylinder space.
  • the communication means is at least one transfer passage.
  • the transfer passage or passages may be provided internally or externally of the stator, or internally or externally of the rotor.
  • At least one of the transfer passages may be valved by the shutter means.
  • the stator comprises at least one inlet port and at least one outlet port.
  • At least one of the ports is substantially adjacent to the shutter means.
  • At least one of said ports is continuously open.
  • at least one of said ports may be valved.
  • Said ports maybe valved by the shutter means.
  • the ports may be valved by pressure-controlled valving means or other valving means.
  • each piston comprises sealing means.
  • the sealing means comprises at least one sealing strip.
  • each such sealing strip is attached to the piston by means of at least one resilient member.
  • the sealing means may, alternatively, comprise a spring seal.
  • sealing strip and the piston device define a recess.
  • the piston and the sealing strip comprise angled front portions which encourage the accumulation of pressure in that region of the annular cylinder space which is adjacent to said front angled portions.
  • the profile of the rotor is at least in part that of a diabolo.
  • the ratio of the angular velocity of the rotor to the angular velocity of the shutter disc is 1:1.
  • the rotary piston and cylinder device is an internal combustion engine.
  • the rotary piston and cylinder device is a fluid pump.
  • the rotary piston and cylinder device is a hydraulic motor/actuator.
  • the rotary piston and cylinder device may be a turbine replacement.
  • the rotary piston and cylinder device may be a compressor or expander.
  • Figure 1 shows a perspective view of a rotary piston and cylinder device 1 of the first type set forth.
  • the device 1 comprises a rotor (11), a stator (7) and shutter means.
  • the stator is of substantially circular outline and comprises a chamber casing 2.
  • the stator need not necessarily be of circular outline.
  • the chamber casing 2 is formed from two side walls 17 and a roof 19 which extend coaxially about the hub axis. Said walls and said roof partially define an annular cylinder space 9. Each of said side walls has formed therein a port, 20 and 22. A gap in the chamber casing 2 allows for the insertion and subsequent rotation of the shutter means.
  • the shutter means comprises a shutter disc 3 in which there is provided an aperture 15.
  • the rotor comprises a piston 13, a hub 11 and two shafts 5.
  • the arcuate profile of the hub 11 is of a radius which is substantially that of the shutter disc 3 so as to receive said shutter disc.
  • the rotor is rotatably attached to the stator by means of suitable bearing means (not shown).
  • Both of said side walls 17 are inclined substantially radially, with respect to the shutter disc 3.
  • the stator 7 further comprises a rim 24 which assists in sealing.
  • the rim extends outwardly at a direction of 90° to the side walls 17 and 19 thereof.
  • the shutter disc 3 may, however, be entirely encased by the stator.
  • the piston 13 extends across the annular cylinder space 9 so as to create a division therein.
  • the piston 13 is rigidly attached to the hub 11.
  • the piston is so shaped that when both the hub and the shutter disc rotate at (substantially) the same angular speed the piston is able to pass through the aperture 15 without prohibiting interference.
  • the effective size of the aperture 15 is dependent on the thickness of the piston 13.
  • suitable transmission means (not shown) is used.
  • the ratio of the angular velocities of the rotor to that of the shutter disc may be 1:2 if two diametrically opposed pistons were provided.
  • the piston 13 is sealed with the walls of the annular cylinder space 17 and 19, around the edge portions 26, 28 and 30.
  • port 20 acts as an inlet port and port 22 acts as an outlet port.
  • the shafts 5 would be powered by a motor (not shown).
  • the arrows A and B show the senses of rotation of the hub 11 and the shutter disc 3 respectively. Fluid is drawn into the inlet port 20.
  • Figures 4 to 7 show snapshots of the device (with the walls 17 and the roof 19 removed) as the piston 13 passes through the aperture 15 in shutter disc 3.
  • the piston blade 13 is angled relative to the shutter disc 3 so as to allow a smaller aperture 15.
  • the lack of reciprocating motions means that acceleration forces impose less of an rpm limit on the device.
  • both the inlet and outlet ports need not necessarily be continuously open.
  • the output may be valved for increased efficiency at larger input/output pressure ratios. This may be achieved by the arrangement shown in Figure 13 and a suitably sized and positioned outlet port in the roof 19.
  • Line A-A is the axis of rotation of the shutter disc 3.
  • An axially extending wall 42 is provided on the shutter disc 3 with an opening 82 such that as the shutter disc 3 rotates, the opening 82 periodically comes in to register with the outlet port thus opening the outlet port at the correct time.
  • a suitably located port could be provided in the rotor which would periodically come in to register with a suitably located static opening.
  • a further alternative would be to provide the outlet port with a pressure controlled valve, other rotary valving means or other valving means.
  • Such a single cylinder design as a pump is of course only one application.
  • Such a design could also be used as an expander (hydraulic motor, turbine replacement).
  • Figures 8 to 11 show a second embodiment of the first type of rotary piston and cylinder device set forth.
  • annular space 9 has been divided into two annular cylinder spaces 32, 34 by the inclusion of a circumferentially extending central wall 35 in the stator 7.
  • the hub 11 now comprises two pistons 36 and 38.
  • the pistons 36 and 38 correspond to end sections of the piston 13 so that the pistons are able to pass through the aperture 15 as the aperture passes through each of the annular cylinder spaces 32 and 34.
  • the annular cylinder space 32 defines an induction/compression space, and the cylinder space 34 defines a combustion/exhaust space.
  • the central wall 35 has formed therein a transfer passage 40.
  • the transfer passage 40 provides a communication means between annular cylinder space 32 on one side of the shutter disc 3 and annular cylinder space 34 on the other side of the shutter disc 3.
  • the transfer passage 40 is shaped so that as the aperture 15 passes through the transfer passage 40, the aperture 15 acts as a valve therein. In this case the transfer passage is opened when the aperture 15 is central to the passage 40.
  • the device operates as follows.
  • Figure 12 shows a sealing arrangement for piston 36 which is on the combustion/exhaust side. A recess is formed in the piston 36 to accommodate a sealing strip 44.
  • the sealing strip 44 is positioned in the recess so that there is a gap 50 on one of said sealing strip.
  • the piston 36 and sealing strip 44 comprise angled front portions 48 and 49 respectively.
  • the angled front portion 48 encourages a build up of pressure in the region of the cylinder space which is adjacent to said angled front portions, resulting in a so-called 'ram' effect.
  • the gap 50 allows pressure to act on the bottom of the sealing strip. The build up of pressure at the front of the sealing strip partially balances the combustion pressure.
  • the relatively narrow transfer passage may act as a venturi, allowing direct injection of fuel into the compressed gas (from an injector on the combustion side of the transfer passage) at a lower pressure than would otherwise be necessary. Direct injection may allow a higher compression ratio to be used (and hence increase the engine efficiency).
  • the energy expended in fuel pressurisation may be reduced by having a split injection system in which part of the fuel is injected into the inlet port (in which the gas that is injected into is around atmospheric pressure) and the rest of the fuel needed to form a combustible mixture is injected into the compressed gas in the transfer passage. This may improve fuel mixing and would still allow a high compression ratio to be used without the risk of pre-ignition that would occur if all of the fuel was added to the inlet port.
  • the circular geometry of the engine may cause fuel to be centrifuged outwards. In the combustion side, this could possibly be controlled with an injector design, or an aerodynamic device by the injector to control amount of mixing. This would allow variable charge stratification (and hence allow power output to be varied without throttling).
  • Another possible modification would be the introduction of a second port on the induction/compression side to allow part of the induced air to be rejected. Control of the amount of air rejected would allow throttling of the device without the pumping losses associated with conventional throttles. Using this form of throttling, the compression ratio is effectively reduced, but the expansion ratio remains the same.
  • FIG. 14 to 17 An embodiment 31 according to the second type of rotary piston and cylinder device set forth is shown in Figures 14 to 17.
  • the device 31 illustrated comprises an outer ring 56, a shutter disc 58 and stator 60.
  • the stator 60 comprises a roof 62 and walls 64a and 64b. Said roof and said walls extend circumferentially around an axis of rotation Y-Y.
  • the walls 64a and 64b comprise two ports 80 and 81, respectively, which are located adjacent to the shutter disc 58.
  • the inlet port and the outlet port may equally be provided in the roof 62.
  • the outer ring 56 is rotatably mounted to said stator 60 by suitable bearing means.
  • the outer ring 56 is provided with an inner surface 68 which is substantially arcuate in outline so as to accommodate the shutter disc 58.
  • the inner surface 68 and stator 60 define an annular cylinder space 70.
  • Said annular cylinder space is sealed by means of sealing rings (not shown).
  • Said outer ring further comprises a piston 72 which extends generally inwardly of the outer ring 56.
  • the piston 72 is provided with inner surface portion 72a and is shaped so as to allow for the movement of said inner surface portion on the roof 62.
  • the shutter disc 58 is provided with an aperture 76 and the shutter disc is mounted within the outer ring 56 so that the shutter disc passes once through the annular cylinder space 70 as illustrated.
  • the shutter disc has an axis of rotation X-X.
  • the sealing of the pistons with the stator may take the form previously described.
  • Suitable transmission means are provided (not illustrated) between the outer ring 56 and the shutter disc 58 so that they both rotate at the same angular velocity.
  • the embodiment described may be used as a pump with an inlet port 80 and an outlet port 81.
  • the outer ring 56 would be driven by suitable driving means (not shown). During operation the outer ring 56 and the shutter disc 58 would rotate and the stator 60 would remain stationary.
  • the inlet and outlet ports may be provided in outer ring 56 and may be valved by openings provided in a static outer housing.
  • one or more of the inlet or outlet ports may be valved by a modification to the shutter disc 58.
  • other suitable valving means may be used.
  • inlet and outlet ports may be provided in the outer ring 56 so that more conventionally the outer ring 56 remains stationary and the rotating shutter disc 58 and the stator 60 rotate inside the outer ring 56.
  • This second type of rotary piston and cylinder device could be adapted to be used as an hydraulic motor.
  • the device could be used as a combustion engine.
  • FIG. 18 A further embodiment according to the second type of rotary piston and cylinder device is shown in Figure 18.
  • the angle between the axis Y-Y of rotation of the rotor ring and the axis B-B of rotation of the shutter disc is 45°.
  • the piston attached to the outer ring is less angled with respect of the axis of rotation of the outer ring which reduces the side thrust on the outer ring.
  • Another advantage of the embodiment shown in Figure 18 is that the external dimensions are further reduced compared to the rotary piston and cylinder device 31.
  • the second type of rotary piston and cylinder device could be used as a pump or hydraulic motor/actuator or as a compressor or expander with the addition of valving means.
  • a number of the devices set forth could be combined, or the cylinder space divided to form multi-stage machines. These could take the form of a combustion engine, if appropriate valving and communication means were provided, or other machines such as multi-stage compressors.
