In-tank fluid transfer assembly

摘要

A fluid transfer assembly includes a housing within which at least a portion of a pump element can be disposed. The housing includes a first surface and a second surface and defines a cavity therethrough. The housing is configured to be coupled to a reservoir such that the first surface is disposed within an interior volume of the reservoir and the second surface is disposed outside the interior volume of the reservoir. The housing includes a seal portion configured to fluidically isolate the first surface from the second surface. The cavity is configured to receive at least a portion of the pump element such that movement of the pump element produces a fluid flow from an inlet opening defined by the first surface and an outlet opening defined by the second surface.

1. An apparatus, comprising:
a housing configured to be coupled to a reservoir containing a fluid such that a first surface of the housing is in fluid communication with an interior volume of the reservoir, the housing including a seal portion configured to fluidically isolate the first surface from a second surface of the housing when the housing is coupled to the reservoir, the housing defining a cavity between the first surface and the second surface; and a pump element, the pump element including a piston at least partially disposed within the cavity such that movement of a portion of the pump element within the cavity produces a flow of the fluid from an inlet opening defined by the first surface to an outlet opening defined by the second surface, the piston including a sealing portion configured to contact a side wall of the housing defining the cavity when the piston reciprocates within the cavity to produce the flow, the first surface of the housing includes a mounting portion configured to be coupled to an actuator, the actuator configured to move the portion of the pump element, the mounting portion configured to retain a filter in a position upstream from the inlet opening.
