Abstract
The invention is an improved conduit flow controller for selectively controlling the flow of fluid through an elongated conduit. The conduit has an aperture defined by a continuous peripheral edge in the sidewall of the conduit. An elongated housing surrounds the aperture and is sealingly connected to the conduit. A conduit stopper is movably mounted in the housing and is positionable in the conduit. The conduit stopper includes a deformable sealing element having opposed flat sides and an edge engageable with the conduit. A carrier is sealingly connected with the sealing element. A resilient seal is mounted on a carrier and is engageable with the continuous edge. The sealing element is cooperative with the seal to close a portion of the conduit to regulate the flow of fluid along the elongated conduit.
