Abstract
A conduit stopper used with a nozzle sealingly mounted on an elongated conduit for selectively interrupting the flow of a fluid through the conduit. The conduit has an aperture communicating with the nozzle for receiving a portion of the conduit stopper. A plug holder is connected to the linear actuator. A retainer cap is secured to the plug holder for movement therewith in the nozzle. A deformable sealing element has one end secured to the retainer cap and an opposite end is adapted to be forced into sealing engagement in the interior of the conduit to interrupt the flow of the fluid through the conduit.
