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.
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.
Abstract:
A fluid pump includes a cam plate that defines an interior cam surface having an eccentric portion and a narrow portion. A hub rotates within the interior cam surface and has a piston cavity that is in communication with an inlet port and an outlet port. A piston member is operably received within the piston cavity to define a suction phase within the eccentric portion and a pressure phase within the narrowed portion. The piston member is biased outward by rotational operation of the hub. During the suction phase, the piston member is biased away from the piston cavity to define a flow cavity that draws fluid from the inlet port. During the pressure phase, the piston member is biased by the narrowed portion into the flow cavity to push the fluid from the flow cavity toward the outlet port.

Abstract:
A sway-bar actuator for a vehicle includes a motor that rotationally operates a lead rod to axially operates a push rod. Operation of the push rod axially operates an attachment fork between an engaged position and a disengaged position. The engaged position is characterized by a unified operation of opposing stabilizing bars. The disengaged position is characterized by independent rotational operation of the opposing stabilizing bars. A sensor rod is coupled to and operates axially with the attachment fork. A sensor assembly has a rotator and a sensor magnet. Axial operation of the sensor rod produces a rotational operation of the sensor magnet. The sway-bar actuator includes an encoder, where a rotational position of the sensor magnet relative to the encoder corresponds to an axial position of the attachment fork and the push rod relative to the engaged and disengaged positions.
Abstract:
A pump assembly includes an electric motor and different selectable pump covers, and is suitable for mounting within a transmission fluid reservoir for transferring automatic transmission fluid. The pump assembly includes a stator housing having a cylindrical cavity for receiving ATF contained in the transmission fluid reservoir. A rotor is rotatably coupled within the cylindrical cavity and has a plurality of magnets arranged about a rotational axis thereof. A flux collector is coupled with the stator housing adjacent to the cylindrical cavity for transferring magnetic flux from one of the plurality of magnets from a first portion to a second portion thereof. A hall sensor is disposed proximate the second portion for sensing magnetic flux in the flux collector, such that the magnetic flux is used to determine a rotated position of the rotor.

Abstract:
A vibration-cancelling module includes a first rotor having a first eccentric body, a second rotor having a second eccentric body, and a stator assembly in electromagnetic communication with the first and second rotors. A central shaft extends between the first and second rotors. The first and second rotors rotationally operate about a common rotational axis with respect to one another between a balanced position and a plurality of eccentric positions. A controller has an accelerometer assembly and a rotor-position sensor assembly. The controller delivers an electrical current to the stator assembly at least based upon the accelerometer assembly. A common housing contains the first and second rotors, the stator assembly, the central shaft and the controller.
