Abstract
A fluid pump includes a housing. A delivery portion includes a delivery pump element disposed within the housing. A return portion includes a return pump element disposed within the housing. A motor is disposed within the housing that drives the delivery pump element and the return pump element via a drive shaft. The delivery portion is configured to deliver fluid from a reservoir to a drive unit. The return pump element is configured to deliver the fluid from a sump assembly of the drive unit to the reservoir.
Claims20
A fluid pump comprising:
- a housing;
- a delivery portion having a delivery pump element disposed within the housing, wherein the delivery pump element includes a delivery inlet and a delivery outlet;
- a return portion having a return pump element disposed within the housing, wherein the return pump element includes a first return inlet, a second return inlet, and a return outlet;
- a motor disposed within the housing that drives the delivery pump element and the return pump element via a drive shaft, wherein the delivery portion is configured to deliver fluid from a reservoir, through the delivery inlet and the delivery outlet and to a drive unit, and wherein the return portion is configured to deliver the fluid from a sump assembly having a first sump and a second sump of the drive unit, through the first return inlet and the second inlet, respectively, and the return outlet to the reservoir;
- and
- a pump cover, wherein the delivery inlet, the delivery outlet, the first return inlet, the second return inlet, and the return outlet deliver the fluid through the pump cover.

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, wherein the delivery pump element includes a delivery inlet and a delivery outlet;
- a return pump element disposed within the return portion of the housing and coupled with the drive shaft, wherein operation of the motor drives 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 first sump and a second sump of the drive unit to the reservoir, and wherein the return pump element includes a return outlet configured to be in communication with a reservoir and a first return inlet and a second return inlet that are configured to be in respective communication with the first and second sumps;
- and
- a pump cover, wherein the delivery inlet, the delivery outlet, the first return inlet, the second return inlet, and the return outlet deliver the fluid through the pump cover.
3 more elements
A fluid pump comprising:
- a motor portion, a delivery pump element and a return pump element;
- a drive shaft that extends from the motor to each of the delivery pump element and the return pump element, wherein the motor, the drive shaft, the delivery pump element and the return pump element are contained within a housing, wherein
- operation of the motor simultaneously drives 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;
- the return pump element is configured to deliver the fluid from a sump assembly of the drive unit to the reservoir;
- the housing includes a porting housing that defines a portion of each of the delivery pump element of the fluid pump and the return pump element of the fluid pump;
- and
- the porting housing partially defines a delivery inlet and a delivery outlet of the delivery pump element and partially defines a first return inlet, a second return inlet, and a return outlet of the return pump element.
