Abstract
A flow control apparatus is provided comprising: a housing including a port; a housing passage disposed within the housing; a flow control member, displaceable, relative to the port, for effecting opening of the port; and a co-operating member. The flow control member and the co-operating member are co-operatively configured such that displacement of the flow control member, relative to the port, is with effect that a force is applied by the flow control member to the co-operating member, with effect that a seating surface is obtained for receiving a flow communication interference body that is being conducted through the housing passage. The seating surface is obtained in response to a deformation effected by the applied force.
