Pump assembly
First Claim
1. A pump assembly for circulating fluids, the pump assembly having a housing including an intake and an outtake, a shaft disposed within the housing, and a rotor, the rotor having an inner peripheral wall encircling the shaft so as to define a bore, the rotor actuated by a magnet disposed within the housing, a propeller fixedly mounted to an upstream portion of the rotor and a stator operatively connected to the magnet so as to rotate the propeller, the pump assembly comprising:
- a passageway extending between the intake and outtake so as to provide a path for fluids, a first portion of the passageway, the first portion having a proximal end positioned at the intake for intaking a portion of the fluid, the first portion of the passageway extending axially along the shaft; and
a chamber disposed within the housing and spaced apart the propeller and downstream the intake, the chamber is completely elevated with respect to the shaft, a second portion of the passageway extending radially from the first portion so as to place the first portion in fluid communication with the chamber, the passageway further including a pipe disposed external to the housing and interconnecting the chamber with the outtake, wherein a first end of the pipe is disposed on an upper portion of the chamber, wherein outgoing fluid creates a vacuum so as to draw air within the passageway into the chamber, the air travelling to the upper portion of the chamber through buoyancy and further into the outtake.

Abstract
The present invention provides a pump assembly having an intake, an outtake, and a rotor rotatably mounted to a shaft. A propeller is fixedly mounted to the upstream portion of the rotor and is rotatable upon actuation of the rotor. A passageway is disposed on the rotor so as to provide a path for fluids to cool the shaft. The pump assembly includes chamber and a pipe. The chamber is disposed within the housing and is located downstream the intake and is in communication with the passageway. The pipe interconnects the chamber with the outtake. An impeller is fixedly mounted to the rotor opposite the propeller and draws air bubbles from the passageway into the chamber.
