titleOfInvention	Variable downhole choke
abstract	A variable downhole choke is disclosed wherein an outer housing includes a selected port pattern of ports and subports and a sleeve having similar ports and subports wherein subports depend from ports on each of the housing and sleeve. The ports/subports are oriented so that upon converging movement of housing and sleeve the sleeve subports align with housing subports before the sleeve ports align with housing ports.
