         47 . A flow control apparatus comprising:
 a housing;   a port extending through the housing for effecting fluid communication between the wellbore string passage and an environment external to the housing;   a flow control member displaceable relative to the port for effecting opening and closing of the port; and   a flow control member retainer biased for releasably retaining the flow control member relative to the housing;   wherein the flow control member and the flow control member retainer are co-operatively configured such that, while the flow control member retainer is releasably retaining the flow control member relative to the housing, the release of the flow control member from the retention relative to the housing is effectible by application of a releasing force that is greater than 3000 pounds.   
     
     
         48 . The flow control apparatus as claimed in  claim 47 ;
 wherein:
 the releasable retention by the flow control member retainer is established by an interference fit between the flow control member retainer and the flow control member 
   
     
     
         49 . The flow control apparatus as claimed in  claim 48 ;
 wherein:
 the flow control member retainer and the flow control member are co-operatively configured such that, while the flow control member is being releasably retained, relative to the housing, by the flow control member retainer, the releasing is effected by deflection of the flow control member retainer relative to the flow control member. 
   
     
     
         50 . The flow control apparatus as claimed in  claim 47 ;
 wherein:

         58 . The flow control apparatus as claimed in  claim 47   wherein:
 the flow control member is displaceable relative to the port between an open position, corresponding to the port being disposed in an open condition, and a closed position, corresponding to the port being occluded by the flow control member; and 
 the flow control member retainer and the flow control member are co-operatively configured such that, While the flow control member is disposed in the closed position, the flow control member retainer is releasably retaining the flow control member, relative to the housing, in the closed position, and while the flow control member is disposed in the open position, the flow control member retainer is releasably retaining the flow control member in the open position. 
   
     
     
         59 . The flow control apparatus as claimed in  claim 58 ;
 wherein:
 the releasable retention by the flow control member retainer, while the flow control member is disposed in the dosed position, is established by an interference fit between the flow control member retainer and the flow control member; and 
 the releasable retention by the flow control member retainer, while the flow control member is disposed in the open position, is established by an interference fit between the flow control member retainer and the flow control member. 
   
     
     
         60 . The flow control apparatus as claimed in  claim 59 ;
 wherein:
 the flow control member retainer and the flow control member are co-operatively configured such that, while the flow control member is being releasably retained, relative to the housing, in the closed position by the flow control member retainer, release of the flow control member from the retention is effectible in response to application of an opening force sufficient to effect deflection of the flow control member retainer relative to the flow control member; 
 the flow control member retainer and the flow control member are co-operatively configured such that, While the flow control member is being releasably retained, relative to the housing, in the open position by the flow control member retainer, release of the flow control member from the retention is effectible in response to application of a dosing force sufficient to effect deflection of the flow control member retainer relative to the flow control member. 
   
     
     
         61 . The flow control apparatus as claimed in  claim 60 ;
 wherein:
 the housing, the port, the flow control member, and the flow control member retainer are co-operatively configured such that, the opening force, in response to whose application is effected the release of the flow control member from the releasable retention in the closed position, is applied in an opposite direction to the closing force, in response to whose application is effected the release of the flow control member from the releasable retention in the open position.
