Definitions

  • the piston elements on the piston member rotate continuously within the passageway in the casing and the vanes intersects the flow passageways in two spaced locations combining with the piston elements to divide the flow passageway into expanding and contracting chambers.
  • the rotation of the piston member and the vanes is coordinated so that elements on the piston member pass through the gaps between adjacent vanes at the locations of the intersection of the vanes with the flow passageway.
  • FIG. 3421 is a view taken along line AA' in FIG. 3a;
  • the cutoff member 12 comprises a spindle 24 extending along its axis of rotation, a plate 26 transversely arranged to the axis and three equiangularly disposed vanes 28 located at the plates circular peripheral edge 27 and extending in the axial direction of the cutoff member.
  • the vanes 28 are spaced apart a suflicient distance to form gaps 30 through which a single piston element 22 can pass between adjacent vanes.
  • FIGS. 10 and 101 the operative arrangement of the piston member 10 and cutofl member 12 is shown so that in rotation the piston elements 22 pass through or mesh with gaps 30 on either side of a vane 28.
  • FIG. 10 and 101 the operative arrangement of the piston member 10 and cutofl member 12 is shown so that in rotation the piston elements 22 pass through or mesh with gaps 30 on either side of a vane 28.
