Abstract:
1. An apparatus for restricting flow through a well conduit, the apparatus having a run-in position and a set position, the apparatus comprising: a housing having a longitudinal bore and a seat disposed within the bore, the seat having a first position when the apparatus is in the run-in position and a second position when the apparatus is in the set position; a plug element support member disposed below the seat and operatively associated with the seat, the plug element support member having a retracted position when the apparatus is in the run-in position and an extended position when the apparatus is in the set position, the retracted position defining a first diameter opening through the plug element support member and the extended position defining a second diameter opening through the plug element support member, the first diameter opening being greater than the second diameter opening; and a plug element adapted to be disposed into the bore and landed on the seat to restrict fluid flow through the bore and the well conduit and to cause the plug element support member to move from the retracted position to the extended position thereby contacting the plug element to provide support to the plug element.
