Abstract
A fluid pump includes a housing, a motor that is disposed within a motor portion of the housing, a delivery pump element that is disposed within a delivery portion of the housing, and a return pump element that is disposed within a return portion of the housing. A drive shaft is coupled to each of the delivery pump element and the return pump element, and operation of the motor contemporaneously operates the delivery pump element and the return pump element via the drive shaft. The delivery pump element is configured to deliver fluid from a reservoir to a drive unit, and the return pump element is configured to deliver the fluid from a sump assembly of the drive unit to the reservoir.
Claims19
A fluid pump comprising:
- a housing having a motor portion, a delivery portion and a return portion;
- a motor disposed within the motor portion, the motor operably coupled to a drive shaft that extends from the motor and through the delivery portion and the return portion;
- a delivery pump element disposed within the delivery portion and coupled with the drive shaft;
- and
- a return pump element disposed within the return portion of the housing and coupled with the drive shaft, wherein operation of the motor operates the delivery pump element and the return pump element via the drive shaft, wherein the delivery pump element is configured to deliver fluid from a reservoir to a drive unit, and wherein the return pump element is configured to deliver the fluid from a sump assembly of the drive unit to the reservoir;
- the drive shaft having a spline, and during the operation of the motor, the spline delivers a portion of the fluid into the motor portion and at least around a rotor of the motor to absorb heat from the motor and from a printed circuit board that is positioned in communication with the motor portion.
A fluid pump comprising:
- a housing;
- a motor disposed within a motor portion of the housing;
- a delivery pump element disposed within a delivery portion of the housing;
- and
- a return pump element disposed within a return portion of the housing, wherein a drive shaft is coupled to each of the delivery pump element and the return pump element, and wherein operation of the motor contemporaneously operates the delivery pump element and the return pump element via the drive shaft, wherein the delivery pump element is configured to deliver fluid from a reservoir to a drive unit, and wherein the return pump element is configured to deliver the fluid from a sump assembly of the drive unit to the reservoir;
- the drive shaft having a spline, and during the operation of the motor, the spline delivers a portion of the fluid into the motor portion and at least around a rotor of the motor to absorb heat from the motor and from a printed circuit board that is positioned in communication with the motor portion.
