Definitions

  • the present invention relates generally toward an approved impeller for a fluid pump. More specifically, the present invention relates toward a monolithic impeller providing enhanced fluid dynamic.
  • Fluids have been used to cool, for example, internal combustion engines for many years.
  • the heat generated by igniting fuel within a combustion chamber is necessarily, rapidly dissipated by fluid flowing through various components of the engine, including the engine block.
  • Fluid pumped through the engine by way of a fluid pump is required to flow at a desirable rate and efficiency necessary to dissipate heat rapidly to maintain efficiency and prevent the engine from overheating. Therefore, a high efficiency pump is desirable.
  • An impeller includes a gear opening defined by a cylindrical member. An inner surface of the gear opening is supplied for receiving a gear shaft.
  • the cylindrical member defines an impeller axis.
  • Each of a plurality of blades includes an arcuate configuration and extends radially outwardly relative to the impeller axis.
  • Each of the plurality of blades include a proximal end disposed proximate the cylindrical member and a distal end disposed radially outwardly from the cylindrical member.
  • a cover member extends radially outwardly to the distal end of the plurality of blades and defines a fluid inlet that is concentric with the impeller axis.
  • a hub member is spaced from the cover member by the plurality of blades and extends radially outwardly from the cylindrical member.
  • the proximal end of the blades extends radially inwardly of the fluid inlet and the distal end of the blades terminates at a common concentric diameter as the outermost portion of the cover member and the hub member.
  • the impeller is formed as a monolithic construction not requiring assembly of any components requiring complex design to achieve desirable performance characteristics.
  • the unique architecture of the impeller of the present invention enhances efficiency of a pump into which the impeller is installed.
  • the impeller of the present invention is constructed of a single component of unitary design reducing cost and ease of manufacture not previously attainable of high efficiency pump impellers.
  • An impeller for a fluid pump is generally shown at 10 of Figure 1 .
  • the impeller includes a gear opening 12 defined by a cylindrical member 14.
  • the cylindrical member 14 includes an inner surface 16 having a plurality of splines 18 disposed in a parallel orientation to an impeller axis a ( Figure 4 ) defined by the cylindrical member 14.
  • the splines 18 are configured to receive a splined drive shaft (not shown) for providing rotary motion to the impeller in a known manner.
  • a plurality of blades 20 each include an arcuate configuration extending radially outwardly relative to the impeller axis a.
  • Each of the blades 20 include a proximal end 22 disposed proximate the cylindrical member 14 and a distal end 24 disposed radially outwardly from the cylindrical member 14.
  • a fluid inlet 26 is defined by a cover member 28.
  • the fluid inlet 26 is concentric with the impeller axis a.
  • the cover member 28 extends radially outwardly from the fluid inlet 26 to the distal end 24 of each of the impeller blades 20.
  • the cover member 28 is substantially perpendicular to the impeller axis a. As used herein, substantially means nearly perpendicular.
  • the fluid inlet 26 is further defined by a flange 30 that is also coaxial with the impeller axis a and extends outwardly from the cover member 28 in an axial direction.
  • the flange 30 includes a radially outward wall 32 defining a cylindrical surface.
  • the flange 30 also includes a radially inward wall 34.
  • the radially inward wall 34 defines a plurality of blade elements 36, each of which are complimentary to one of the plurality of blades 20.
  • Each of the blade elements 36 defines a notch 38 in the radially inward wall 34.
  • the proximal end 22 of each blade 20 is aligned with one of the notches 38 such that the proximal end 22 extends radially inwardly from the notch 38 beyond the flange 30. Therefore, a hypothetical ring defined by the plurality of distal ends 24 of the blades 20 is disposed radially inwardly of the flange 30, while, the distal end 24 of each blade 20 is spaced
  • the proximal end 22 of each blade 20 includes an end portion 40 that is distinguishable from a body 42 of the blade 20.
  • the end portion 40 of the proximal end 20 terminates at an angle that is offset from the impeller axis a. Therefore, it should be understood that the end portion 46 is disposed at an acute angle relative to the axis a.
  • the end portion 40 is slightly offset radially outwardly from the body 42 of each blade 20. The unique interaction between the end portion 40, the proximal end 22 extending radially inwardly of the flange 30 and the notch 38 defined by each blade element 36 is believed to provide advantageous fluid dynamics resulting in an increased efficiency of the pump impeller 10.
  • a hub member 44 is spaced from the cover member 28 by the blade 20.
  • the hub member 44 terminates proximate the impeller axis a at the cylindrical member 14 and extends radially outwardly to the distal end 24 of the blades 20. Therefore, the distal end of the blades 20, and the outermost portion of the cover member 28 and hub member 44 are disposed at a common concentric diameter from the impeller axis a.
  • the outermost portion of the cover member 28 and the hub member 44 are substantially perpendicular to the impeller axis a.
  • the hub member 44 presents a cross-sectional, arcuate or concave configuration progressing toward the cylindrical member 14 best seen in Figure 3 .
  • a lip 46 extends in an axial direction at the outermost portion of the hub member 44.
  • the blade element 36 disposed in the radial inward wall 34 of the fluid inlet 26 not only enhance fluid dynamics improving the impeller efficiency, but that the blade element 36 also serve as a beneficial manufacturing feature.
  • the blade element 36 also functions as a die relief enabling the impeller 10 to be of a unitary or monolithic design requiring no assembly.
  • a single die (not shown) is used to mold the impeller 10 without requiring assembly of various components as is known to prior art impellers of this complexity.
  • the blade element 36 provides a two-fold function further enhancing not only performance of the impeller 10 but also manufacturability.
  • impeller 10 is molded from a polymeric, or reinforced polymeric material of a single die cycle eliminating manual labor associated with assembling two piece impellers known of the prior art.
