Abstract

ABSTRACT A door-operated pump assembly may include a housing defining a chamber having an inlet and an outlet, a displacement member arranged to move within the chamber between first and second positions, an actuator coupled to the displacement member, and a door coupled to the actuator. The actuator may be operable to move the displacement member between the first and second positions. The door may be configured to move the displacement member between the first and second positions when the door is moved between a first door position and at least one second door position. The displacement member may be operable to inhale a substance into the chamber through the inlet and to exhale a substance from the chamber through the outlet.
