Abstract:
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.
