Abstract
A submersible pumping apparatus for displacing transmission fluid includes a pump operably coupled with a motor. A filter housing is attached to the pump and has a cavity with an inlet aperture extending to an exhaust port of the pump. A fluid filter is engaged with the cavity and has a filter cover with a relief valve disposed within an outlet aperture that extends from the cavity to an exit port on the filter cover. The relief valve is configured to open when a fluid pressure from the exit port reaches a threshold and close when the fluid pressure is below the threshold. A rotor cover is attached to the motor and has a circuit board for operating the motor, such that the rotor cover is configured to prevent the circuit board from being exposed to liquid.
Claims20
A submersible pumping apparatus for displacing transmission fluid, comprising:
- a pump operably coupled with a motor;
- a filter housing attached to the pump and having a cavity with an inlet aperture extending to an exhaust port of the pump;
- a fluid filter engaged with the cavity and having a filter cover with a relief valve disposed within an outlet aperture that extends from the cavity to an exit port on the filter cover;
- and
- a rotor cover attached to the motor and having a circuit board for operating the motor, wherein the rotor cover is configured to prevent the circuit board from being exposed to liquid.
A pumping apparatus for displacing fluid, comprising:
- a pump adapted to operably couple with a motor;
- a filter housing coupled with the pump and having a cavity with an inlet aperture extending to an exhaust port of the pump;
- and
- a fluid filter engaged with the cavity and having a filter cover sealed around a periphery of the cavity, wherein a relief valve is disposed in the filter cover between the cavity and an exit port, such that the relief valve is configured to open when a fluid pressure from the exit port reaches a threshold and close when the fluid pressure is below the threshold.
A filter module for a pump within a fluid reservoir of a vehicle, comprising:
- a filter housing adapted to couple with the pump and having a filter cavity with an inlet aperture for extending to the pump;
- a filter cover sealably coupled with a periphery of the filter cavity;
- a filter element for filtering fluid displaced by the pump coupled with an inside surface of the filter cover;
- and
- a relief valve disposed in the filter cover between the filter element and an exit port on the filter cover and configured to open when a fluid pressure from the exit port reaches a threshold and close when the fluid pressure is below the threshold.
A submersible pumping apparatus for displacing fluid, comprising:
- a motor housing having a drive coil;
- a rotor shaft rotatably engaged within the motor housing and configured to operably couple with a positive displacement pump;
- and
- a rotor cover attached to the motor and comprising:
- a bearing integrally coupled with an interior side of the rotor cover and rotatably coupled with an end of the rotor shaft;
- and
- a circuit board for operating the drive coil to control rotation of the rotor shaft, wherein the rotor cover is configured to prevent the circuit board from being exposed to liquid.
