Abstract
A fluid pump includes a pump element in communication with an inlet and an outlet. Rotation of the pump element generates a suction at the inlet and pressure at the outlet. The suction and pressure cooperate to move a fluid through a fluid path. An accessory fluid path is in communication with the inlet and outlet. The accessory fluid path includes a thermistor in communication with the accessory fluid path. The thermistor monitors a temperature of the fluid within the accessory fluid path.
Claims20
A fluid pump comprising:
- a motor positioned within a housing;
- a pump element attached to the motor, wherein rotation of the pump element generates an inward suction and an outward pressure that cooperatively move a fluid through a fluid path that includes an inlet and an outlet;
- and
- an accessory fluid path in communication at least with the outlet of the fluid path, wherein the pump element directs an excess portion of the fluid through the accessory fluid path, the accessory fluid path having a low-restriction return path that provides a continuous flow of the excess portion of the fluid through the accessory fluid path and to an outlet orifice during operation of the pump element, wherein
- the housing includes contours and a central portion that define a portion of the accessory fluid path, wherein the contours align with one side of an outer wall of the housing;
- a thermistor is in communication with the accessory fluid path proximate the contours and the central portion;
- the fluid path and the contours are positioned at opposing ends of the housing;
- the continuous flow of the excess portion of the fluid is directed between the contours and the fluid path between a portion of the motor and the outer wall;
- and
- the low-restriction return path is configured to maintain a temperature of the continuous flow of the excess portion of the fluid within the contours to be similar to a temperature of the fluid in the fluid path.

A fluid pump comprising:
- a pump element in communication with a fluid path having an inlet and an outlet, the pump element including a rotor and a stator within a housing;
- an inlet orifice in communication with the pump element, wherein the pump element and the inlet orifice direct a primary flow of a fluid to the outlet and an excess flow of the fluid into an accessory fluid path, the accessory fluid path having a portion of the fluid, wherein the accessory fluid path extends between the rotor and an outer wall of the housing;
- and
- a printed circuit board housing that includes contours that align with one side of the outer wall of the housing;
- wherein
- the accessory fluid path includes a low-restriction return path that moves the excess flow of the fluid as a continuous flow through the accessory fluid path and toward the fluid path;
- the low-restriction return path is configured to maintain a temperature of the excess flow of the fluid in the contours of the accessory fluid path to be similar to a temperature of the primary flow of the fluid;
- a thermistor is positioned in communication with the contours to simultaneously monitor, in real time, the temperature of the excess flow of the fluid in the accessory fluid path and the temperature of the primary flow of the fluid in the fluid path;
- and
- the contours of the printed circuit board housing include a central portion, wherein the contours extend between the central portion and the outer wall of the housing.

A fluid pump comprising:
- a stator and a rotor in electromagnetic communication and disposed within a housing;
- a pump element attached to a first end of a drive shaft of the rotor;
- an inlet orifice in communication with the pump element that diverts a primary flow of a fluid to an outlet and an excess flow of the fluid through the inlet orifice and into an accessory fluid path;
- an outlet orifice in communication with the pump element, the outlet orifice directing the excess flow of the fluid from the accessory fluid path to a primary fluid path, wherein the primary fluid path extends between an inlet and the outlet;
- and
- a printed circuit board assembly of the housing that includes contours that are positioned at a second end of the drive shaft that opposes the first end, the contours extending between a central portion and one side of an outer wall of the housing;
- wherein
- the accessory fluid path directs the excess flow of the fluid from the inlet orifice to the contours;
- the accessory fluid path includes a low-restriction return path that moves the excess flow of the fluid as a continuous flow through the accessory fluid path and toward the outlet orifice;
- the low-restriction return path is configured to maintain a temperature of the excess flow of the fluid in the contours of the accessory fluid path to be similar to a temperature of the primary flow of the fluid;
- and
- a thermistor attached to the printed circuit board assembly and positioned in communication with the contours to simultaneously monitor, in real time, the temperature of the excess flow of the fluid in the accessory fluid path and the temperature of the primary flow of the fluid.
