RIGID COUPLING DEVICE FOR PRESSURIZED-FLUID CONDUITS

摘要

The rigid coupling device includes a closure valve (45) extended by a retractable sliding stop member (32) of general tubular shape made from elastically deformable material, having at least one outward radial projection (34) forming a stop against a corresponding inward radial projection (40) of a movable interior body (22) that contains the valve. The stop member (32) has an open end (35) opposite the opening of the cylindrical cavity of one end (29) connecting to the conduit. Simultaneous withdrawal of the interior body (22) and of the valve (45) into the interior body (22) has the effect of causing this open end (35) to contract, forcibly inserting it into the cylindrical cavity of the connecting end (29) in such a manner as to overcome the stop (34).
