Fluid e.g. water, conduit unit, has sealing piece moving freely between fluid flowing position, where hollow parts are connected, and closing position, where connection is sealed, and free from any return elastic stress

摘要

The conduit unit has a tab connector with hollow parts (1, 3), where the part (3) is connected to a female coupling. The parts are connected by a fluid flowing zone (4) having a sealing piece (5). The piece is moved freely between a fluid flowing position, where connection exists between the parts and a closing position, where the connection is sealed. The sealing piece is free from any return elastic stress.
