Definitions

  • This invention relates to rotary- umps or engines.
  • Rotary pumps or engines are described, for example, in GB 677 674.
  • the present invention provides a rotary pump or engine of the eccentric chamber and pivoting vane type comprising a plurality of parallel plates to thereby define one or more eccentric chambers, said plates being compressed together, and one or more vanes within said one or more eccentric chambers pivoted at one end to a core member and having pivoted tip members at the other end, said core member rotating relative to said one or more eccentric chambers.
  • working media such as air, steam or other fluids or mixtures thereof may be worked upon or work in volumes of variable capacity formed by curved vanes oscillating within chambers of rectangular cross section.
  • the bodies of the pumps or engines of the invention contain the chambers of variable capacity which are formed by a series of laminated parallel chamber plates, dividing plates and end plates held together by a number of tension members passing through the plates. This type of construction enables conventional machine tools to be used for the production of the pump or engine parts, and the. simplicity of the design will permit low costs of manufacture.
  • the vanes of the pump or engine of the invention are preferably curved, pivoted at one end to a core member and have a pivoted tip member at the other end.
  • the vanes conveniently taper from their pivot end towards their tip members.
  • the vanes in accordance with this invention lie in chambers formed in plates of the same thickness as the vanes and have dividing plates on at least one side of each chamber.
  • the chamber in each chamber plate is the result of an eccentric circle or other profiled form cut from through the full depth of the chamber plate, the inner surface of which forms the peripheral surface of the chamber.
  • the variable volumes formed by relative rotational movement of the vanes within their chambers enable the device to act as a pump or engine.
  • the body of the pump or engine generally consists of a laminated assembly of plates being the endplates containing the bearings of the machine and between these, the alternate chamber plates and dividing plates according to the number of chambers desired for the particular machine. However, a small version of the machine may have only one chamber plate between endplates and bearings. If desired, fluid delivery valves or intake ports may be positioned in the side or endplates of the pump, or alternatively valves may be provided to pass e.g. compressed air or gas into a central hollow shaft.
  • the vanes may conveniently be provided with light springs to keep the vane tips in contact with the chamber peripheral surface when pivoting outwards. As relative movement takes place between the chamber plate and the vanes, the eccentric surface of the chamber forces the vane to pivot inwards.
  • the pivoting tip of the vane itself forms a pressure operated seal, and the sides of the vanes may also have pressure operated seals.
  • fluid may be drawn through radial ducts formed between the chamber peripheral surface and the outer surface of the chamber plate.
  • fluid may be drawn through ports or grilles located in the dividing or endplates of the pump.
  • ducts, ports or grilles for fluid entry are so positioned that the relevant vane will close such openings when that vane begins to pivot inwards under the pressure of the chamber plate eccentric surface.
  • a conventional spring pressure seal may be provided through the full depth of the chamber.
  • Each chamber may have one, two or more vanes and a complete machine may have one or more chambers.
  • the rotational axis of a pump or engine according to this invention may be vertical, horizontal or in any other plane.
  • Rotary steam engines preferably comprise a stationary outer body comprising the laminated assembly of plates previously described, with an inner rotor carrying the vanes which lie in chambers and between dividing plates and/or end plates as already described.
  • the inner peripheral surfaces of the chamber plates are generally not in the form of eccentric circles but have profiles designed to obtain optimum benefit of steam expansion and are offset in relation to the central axis.
  • a feature of engines in accordance with this invention is that relative movement between vanes and chamber surface is opposite to the relative movement when functioning as pumps, which means that for engines, the pivot end of the vane is leading and the vane tip trailing within a stationary outer body.
  • chambers conveniently differ one from another and the dividing plates between chambers preferably incorporate ports designed to permit optimum transfer of steam from one chamber to an adjacent chamber.
  • the machine could conveniently be a triple expansion rotary steam engine.
  • the steam may be admitted to the first chamber either via a tangential port or via ports in the rotor and hollow central shaft similar to an air engine or internal combustion engine application of this invention.
  • the first chamber is a high pressure (HP) chamber and within the chamber may be one or more vanes, preferably three, each being attached to the rotor by its pivot pin at an angular separation of 120°.
  • IP intermediate pressure
  • the third chamber in this design is the low pressure (LP) chamber, the width and depth of the chamber being again greater than those of the adjacent IP chamber.
  • This LP chamber also accommodates the same number of vanes as in the preceding
  • vanes are attached to the rotor by their pivot pins but in advance of the vanes in the IP chamber so that the relevant vane in the LP tract receives beneficially the steam passing out of the IP chamber when the appropriate vane in the IP chamber uncovers the port in the dividing plate between the IP and LP chambers.
  • the function of following vanes in both IP and LP chambers is as described for the HP and IP chambers except that radial exhaust ports may be formed in the LP plate through which steam may pass to a condenser.
  • a triple expansion rotary steam engine in accordance with one embodiment of this invention has been described above but a single chamber steam motor is equally applicable whilst a multiple chamber rotary steam engine will follow the same principles of construction and operation.
  • the outer body comprising the laminated assembly of plates is also conveniently stationary while the centre portion consists of a rotating rotor.
  • the chamber peripheral surfaces may be not in the form of eccentric circles but have profiles designed to obtain optimum benefit of air or gas expansion, and offset in relation to the central axis.
  • the air or gas entry port may be in the expansion portion of the relevant chamber fed from a rotary sleeve valve, in which case the shaft gf the machine rotates and drives the rotary sleeve valve.
  • the TOtOr rotates on a stationary hollow shaft and air or gas entry is via a curved duct or ducts in the rotor admitting air or gas from the stationary hollow shaft.
  • the relevant ports in the hollow shaft and rotor are so positioned as to align at a pre ⁇ determined position in the rotation of the rotor to give optimum entry and expansion of compressed air or gas.
  • Air motors or internal combustion engines in accordance with this invention may have one or more chambers, and the
  • chambers may have one- or more vanes.
  • the preferred number of vanes is two in each chamber positioned on the rotor with pivot pins at an angular separation of 180°.
  • injector and/or ignition equipment are generally provided in the chamber plate where expansion begins to take place.
  • the chamber plates are generally designed to provide optimum flame propagation.
  • Figure 1 is a cross-section through an air compressor or fluid pump in accordance with the invention
  • Figure 2 is a cross-section through a triple expansion steam engine in accordance with the invention.
  • FIG. 3 is a cross-section through an air motor or internal combustion engine in accordance with the invention.
  • Figure 4 is a section along the line A-B of the pump illustrated in Figure 1.
  • the positive displacement pump illustrated in Figures 1 and 3 comprises an outerbody 1 consisting of a laminated assembly of chamber plates 2, dividing plates 3 and endplates 4, which are held in compression by tension members e.g. screws or bolt ' s 5. all of which rotate about a stationary core 6.
  • Each chamber plate 2 has curved radial air intake ducts 7 formed in the advancing sector of the chamber eccentric, and has two curved vanes 8 in it.
  • Each chamber plate has a conventional spring pressure seal 9 through the full depth of the chamber at the position of minimum eccentricity.
  • the vanes have hinged tip members 10 and the complete vanes are attached by pivot pins 11 to the stationary core.
  • the core comprises segments, one to each chamber which are keyed onto the central hollow shaft 12 with keys 13 and are held together by threaded members e.g. screws or bolts 14 parallel to the shaft 12.
  • the segments of the core 6 are fitted with valves 17 to allow air in the diminishing space of the chamber to pass into the bore of the hollow shaft 12.
  • the triple expansion rotary steam engine shown in Figure 2 comprises a laminated outer body 21 comprising chamber plates 22, dividing plates (not shown) and endplates (not shown) held in compression by tension members 23.
