Definitions

  • shocks and vibrations are-unavoidable.
  • paddles, vanes and blades necessarily introduces numerous defects andY limitations and adds to the complication,l cost of'production and maintenanceof the machine.
  • the object of my present invention is to overcome these deficiencies in a paratus designed for the propulsion of ids and to e ect thereby the transmission and .transformation of mechanical energy through the agency of iuids in a more perfect manner, andby means sim ler'and more economical 'than those hereto ore employed. I accoml' plishthis by causing the .propelled iuid to .versely, if the body be place Vmolecular separation.
  • Figure 1 is a partial end view
  • Fig. 2 is a vertical cross section of a pump or compressor constructed and adapted to be ⁇ operated in accordance with my invention.
  • the device illustrated y contains a runner composed ofa plurality of flat rigid disks 1 of a suitable diameter, keyed to a shaft 2, and held in position by a v threaded nut 3, a shoulder t and washers 5,
  • Each disk has a number of central openings 6the solid por- 'tions between which form vspokes 7, preferably curved,as shown, for the purpose of reducing the loss of energy due to the impact of the fluid.
  • the runner is mounted 1n a two part Yvolute casing 8, having stuin boxes 9, and inlets 10 leading to its centra portion.
  • a graduall Widening and rounding outlet 11 is provi ed, formed with a ange for connection to a pipe as usual.
  • the casing 8 rests upon a base 12,
  • the spacing of the disks in any given lmachine will be determined by the conditions and requirements of special cases. It may be stated that the intervening distance should be the reater, the larger the diameter of the dis s, the longer the spiral path of the fluid and the greater its viscosity. In general, the spacing should be such that the lentire mass of the fluid, before leaving the runner, is accelerated to a nearl uniform velocity, not much below that of the periphery of the disks under normal working con ditions and almost equal to it when the outlet is closed and the particles move in con-4 centric circles.
  • such a pump can be made without openings and spokes in the runner, as by using one or more solid disks, each in its own casing, in which form the machine will be eminently adapted for sewage, dredging vund the like, when the water 1s charged with foreign bodies and spokes or van especially objectionable.
  • a inachinefor propelling or imparting energy to fluids comprising in combination a plurality of spaced disks rotatably mounted :uid having plane surfaces, an inclosing casing, ports of inlet at the central portion of said casing and through which the Huid is adapted to be introduced to the axial por ⁇ tions of the disks, and ports of outlet at the peripheral portion of the casing through which the Huid, when the machine is driven by power, is adaptedto be expelled, as set forth.
  • a machine for propelling or imparting energy to fiuids comprising in combination a volute casing provided with ports of nlet and outlet at its central and peripheral portions, respectively, and a runner mounted within the casing and composed of spaced disks with plane surfaces having openings adjacent to the axis of rotation.
  • a rotary pump comprising in combination a plurality of' spacedl disks Witln plane surfaces mounted on a rotatable shaft and provided with openings adjacent thereto, a volute casing inclosing the said disks, means for admitting a fluid into that portion of the casing which containsthe shaft and an outlet extending tangenti-ally from' the peripheral portion of said casing.
