Abstract

A movable seal for interfacing between a first surface and a second surface includes a floating portion attached to a non-floating portion by a flexible coupling portion, wherein the non-floating portion is coupled to the first surface by nesting in a groove on the first surface, and wherein the non-floating portion forms a seal between the first and second surfaces when the first surface moves relative to the second surface in a first direction, and wherein the non-floating portion does not form a seal between the first and second surfaces when the first surface moves relative to the second surface in a second opposite direction.
