Abstract:
1. An alignment system for accurately setting the flow rate of a flow selector device that selectively fixes the flow rate of a fluid; the system comprising: a flow selector device including a fluid inlet, a fluid outlet and a flow rate selection mechanism that is rotated between a plurality of pre-selected positions corresponding to pre-determined flow rates; a knob providing a grip to rotate the flow rate selection mechanism, the knob comprising a body having a distal portion, a proximal portion, and at least one registering element; a cover movable between an open position providing access to the knob and a closed position restricting access to the knob, the cover further including at least one cover element that: (i) engages the distal portion of the knob when the registering element is misaligned with a pre-selected position preventing the cover from attaining its closed position, and (ii) engages with the registering element when the registering element is aligned with a pre-selected position allowing the cover to attain its closed position, wherein the knob is positioned between the flow rate selection mechanism and the cover.
