Bladeless fluid propulsion pump

Abstract

A bladeless pump for fluids, including gases or gases having particulate matter therein, which may be driven by a motor. The bladeless pump consists of an assembly of rotors or discs stacked one against the other. Each rotor or disc has a runner portion on an outer area spaced away from the center of the disc or rotor and a central portion which has two or more spokes. The spokes have inter-spoke openings. The spokes are typically thicker than the rest of the discs. When many discs are placed together and spun on an axle driven by a motor, then air may be drawn in adjacent the rotor assembly where the inter-disc openings are located, and compressed as they enter the inter-disc area. A volute that is spiral shape is provided adjacent the outer rim of the disc assembly which receives the pressurized air and releases it from a motor housing. Applicant's bladeless pump may include a base for receiving the rotor housing thereon and receiving the motor thereon, the base may include a housing to substantially enclose the motor and the motor housing.

1 . A bladeless pump comprising:
 a rotor housing, including walls defining a volute, the volute having a knife edge, a volute fluid outlet, and walls defining a rotor feed opening;   fluid inlet walls, including walls defining a fluid inlet and passageway walls for carrying fluid from the fluid inlet to the rotor feed opening;   a rotor assembly, including a multiplicity of rotors, each rotor having a runner portion, the runner portion having a first thickness T1, walls defining a multiplicity of central openings, and a multiplicity of spokes, the spokes including walls defining an axle opening, the spokes having a second thickness T2, the second thickness greater than the first thickness Ti;   an axle; and   a retaining collar; and
 wherein the rotors engage on the axle; 
 wherein the rotor housing substantially encloses the runner portions of the rotor assembly; and 
 wherein the spokes of the rotors include alignment locking means. 
   
     
     
         2 . The bladeless pump of claim  31 , wherein the alignment locking means includes projecting pins and pin receiving indentations. 
     
     
         3 . The bladeless pump of claim  32 , wherein the spokes of the rotors contain pins having a first shape and pins having a second shape with corresponding receiving indentations having substantially matching receiving shapes. 
     
     
         4 . A bladeless pump comprising:
 a rotor housing, including walls defining a volute, the volute having a knife edge, a volute fluid outlet, and walls defining a rotor feed opening;   fluid inlet walls, including walls defining a fluid inlet and passageway walls for carrying fluid from the fluid inlet to the rotor feed opening;   a rotor assembly, including a multiplicity of rotors, each rotor having a runner portion, the runner portion having a first thickness T1, walls defining a multiplicity of central openings, and a multiplicity of spokes, the spokes including walls defining an axle opening, the spokes having a second thickness T2, the second thickness greater than the first thickness Ti;   an axle; and   a retaining collar; and
 wherein the rotors engage on the axle; 
 wherein the rotor housing substantially encloses the runner portions of the stack rotor assembly; and 
 wherein the endplates are planer, conical or labyrinthine shaped. 
   
     
     
         5 . The bladeless pump of claim  34 , wherein the endplates are connected to the retaining collar with fan-like struts. 
     
     
         6 . A bladeless pump comprising:
 a rotor housing, including walls defining a volute, the volute having a knife edge, a volute fluid outlet, and walls defining a rotor feed opening;   fluid inlet walls, including walls defining a fluid inlet and passageway walls for carrying fluid from the fluid inlet to the rotor feed opening;   a rotor assembly, including a multiplicity of rotors, each rotor having a runner portion, the runner portion having a first thickness T1, walls defining a multiplicity of central openings, and a multiplicity of spokes, the spokes including walls defining an axle opening, the spokes having a second thickness T2, the second thickness greater than the first thickness Ti;   an axle; and   a retaining collar; and
 wherein the rotors engage on the axle; 
 wherein the rotor housing substantially encloses the runner portions of the stack rotor assembly; and 
   further including a motor and a bearing to align the axle with the rotor housing and the stack assembly;
 wherein the bearing is substantially in the plane of the walls adjacent the rotor feed opening.
