摘要： A valve assembly may include a valve having an upper valve surface and a lower valve surface. The valve may be movable in a slot in a housing between an open position and a closed position, and the slot may have an upper slot surface and a lower slot surface. The valve assembly may include a biasing member movably positioned within the housing that may be configured to urge the valve toward one of the upper slot surface and the lower slot surface.
