ABSTRACT:
A flow control device with an inlet for the flow of fluid and a movable member sealing the inlet and having a flexible body for controlling flow by the extent to which the flexible body of the movable member is buckled. The movable member extends between the inlet and an outlet and is expandable laterally with respect to the axis of a channel for the outlet in order to control flow. A member external to the flow control device can activate the moveable member which can take the form of a plug seated in the inlet by depressing the plug from its seat. The movable member also can be bell-shaped with its upper portion sealing the inlet and slotted walls straddling the outlet.
