Definitions

  • the invention relates to the field of rotary expanders.
  • Rotary expanders are well known. Known rotary expanders are either relatively expensive to manufacture, relatively inefficient or relatively expensive to maintain.
  • Forming one aspect of the invention is an improvement to an expander of the type that is used to extract power from a supply of pressurized fluid and that includes: a housing, a rotor and control means.
  • the housing has a rotation axis; defines a hollow interior having an annular surface orientated parallel to the rotation axis and through which the rotation axis extends; and defines one or more ports which extend through the housing to the interior.
  • the rotor is mounted in the housing for rotation about the rotation axis and has a body and vanes.
  • the body has an outer tubular surface, the tubular surface having defined therein a plurality of voids.
  • the vanes are provided one for each of the voids.
  • Each vane has a seal defining a tip of the vane; is mounted in the void for which it is provided for movement between a retracted position and an extended position; and is adapted such that, upon rotation of the rotor in the housing, movement of the vane between the extended and retracted positions causes the tip seal to sweep the annular surface.
  • the control means is for controlling movement of the vanes and access to the ports such that the vanes create chambers which increase in volume when in
  • the improvement comprises: for each vane, a pivot axis orientated parallel to the rotational axis and about which said each vane pivots between the extended and retracted positions.
  • FIG. 1 is a perspective view of an expander according to an exemplary
  • FIG. 2 is a view similar to FIG. 1 with a portion removed for clarity;
  • FIG. 3 is a view of the structure of FIG. 2 from another vantage point
  • FIG. 4 is a view similar to FIG. 3 with a further portion removed and partially exploded, for clarity
  • FIG. 5 is a view of a portion of the structure of FIG. 3;
  • FIG. 6A is a cross sectional, partially schematic view of an expander according to another exemplary embodiment of the invention.
  • FIG. 6B is a view of the structure of FIG. 6A in another position
  • FIG. 6C is view of the structure of FIG. 6A in yet another position
  • FIG. 7 is a view similar to FIG. 6A showing, in partially schematic cross- section, an expander according to yet another embodiment
  • FIG. 8 is a view of another embodiment of the structure of encircled area 8 of
  • FIG. 4
  • FIG. 9 is a view similar to FIG. 6A of another exemplary embodiment.
  • FIG. 1 An expander 20 according to an exemplary embodiment of the invention is illustrated in FIG. 1 and will be understood, upon review of FIG. 1 - FIG. 5, to include a housing 22, a rotor 24, control means 26 and end seals 28.
  • the housing will be understood to: have a rotation axis R-R; define a hollow interior 30 having an annular [generally oval] surface 32 orientated parallel to the rotation axis and through which the rotation axis extends; define one or more ports 34 which extend through the housing to the interior; and be defined by a tubular block 36 disposed between a pair of end plates 37.
  • the rotor will be seen to be disposed in the interior and to include a body 38, a shaft 40 and vanes 42.
  • This body will seen to be a generally cylindrical metal structure suitable for construction with wire EDM and drilling and to have a central bore 43 and an outer tubular surface 44, the tubular surface having defined therein a plurality of voids 46 and, associated with each void, a respective socket 48, each void being defined in part by an arcuate slot 50 and each socket defining a respective pivot axis P-P.
  • the shaft passes through the bore.
  • the vanes are provided one for each of the voids.
  • Each vane has a seal 52 defining a tip of the vane, terminates in a pintle 54 which is mounted in the associated socket for rotational movement, as discussed further below, and includes an arcuate slider 56. Each vane further has vents 57 defined therein.
  • the control means will be seen to include springs 58.
  • the end seals are defined in part by body seals 60 carried by and spring mounted to the body and in part by vane seals 62 carried by and spring mounted to the vanes, all to project to and seal against the end plates.
  • the seals 60,62 in the exemplary embodiment are spring-mounted within slots provided in the vanes and body.
  • the foregoing structure provides the functionality normally associated with an expander, namely, pressurized fluid is introduced into the interior through the ports, thus creating force on the trailing edges of the vanes which causes the rotor to turn.
  • the control means controls movement of the vanes and access to the ports such that the vanes create chambers which increase in volume when in communication with the source of fluid at high pressure.
  • the creation of a chamber that increases in volume when in communication with the source of pressurized fluid is best seen in the schematic views of the alternate expander of FIGS. 6A-6C, wherein a single vane is enumerated, for clarity, a chamber is seen to be created as the vane nears the port, as per the sequence of FIG. 6A, 6B, and the chamber C will be seen to increase in volume in the sequence of FIG. 6B, 6C.
  • annular surface and the tubular surface can both be oval, with the rotor centered in the interior.
  • An embodiment with a modified block 36' to achieve this is shown in FIG. 7.
  • the modified block 36' also shows that the number of ports can be adjusted routinely by persons of ordinary skill in the art.
  • a large range of customized volumetric expansion ratios can be achieved using readily available metered inlet controls without altering the base design.
  • springs are shown to bias the movement of the vanes at low speeds and startup, this is not necessary: there are many viable ways to control the vane movement such as magnets 64 as shown in FIG. 8 which repel vanes 42 from the body 38. Compressed gas and cams/rollers, not shown, can also be used.
  • seals constitute sacrificial wear components
  • numerous lubricants can be employed including wet lubricants (oils) and dry lubricants (graphite, bronze, molybdenum disulfide, etc.) to increase life.
  • wet lubricants oil
  • dry lubricants graphite, bronze, molybdenum disulfide, etc.
  • axle-supported bearings can be provided at the ends of the sockets, not shown. Bearings can also be provided to facilitate movement of the sliders, as indicated by bearings 66 in FIG. 9.
  • FIG. 9 also shows that the annular surface can be cylindrical, which has advantages in terms of machining.
  • the expander can run in constant pressure mode like a hydraulic motor providing maximum torque at lowest speeds. This can be used as a safety fallback, low expansion mode with full torque at low speed should the control means fail.

Abstract

L'invention concerne un perfectionnement apporté à un détendeur. Le détendeur est du type qui comprend des aubes qui s'étendent et se rétractent à partir d'un corps de rotor pendant une rotation et créent des chambres dont la taille augmente et diminue. Le perfectionnement comprend, pour chaque aube, un axe de pivotement orienté parallèlement à l'axe de rotation et autour duquel chaque dite aube pivote entre les positions étendue et rétractée.
