Zusammenfassung:	An apparatus, system and method for providing a flow restrictor suitable for inclusion in an aspiration flow of an ocular surgical device. The flow restrictor includes a conical valve head suitable for insertion into a valve stage, wherein, upon the insertion, the valve head at least substantially impedes the aspiration flow; a flexible spider membrane having a plurality of valve passages that open and close with the flexation of the membrane, wherein the membrane is connective with the valve head and forces the insertion of the valve head into the valve stage proportionally to the aspiration flow; a circular receiving plate for receiving the aspiration flow, wherein the circular receiving plate imparts the proportional insertion to the membrane; and a plurality of ribs integral to at least one of the valve head and the valve stage that provides a minimum for the aspiration flow when the insertion is full.
