Plug members are located at the ends of the secondary space to sealingly define the secondary space and the outer peripheral wall of the tube defining the secondary space portion is provided with one or more holes from which a fluid maintained under pressure in the secondary space is sprayed outwardly. The main space and the secondary space are connected by a passage having means for adjusting the flow rate of fluid from the main space to the secondary space.Field of SearchTERMINAL OUTLET MEANS CONNECTED IN SERIES FOR THROUGH FLOWPOROUS OR EXTERNAL WICK DISCHARGE MEANS ADJOINED CONTIGUOUS ELONGATED SPRAY CONDUITS (E.G., PARALLEL CONDUITS) CONDUIT OR NOZZLE ATTACHED IRRIGATION-TYPE DECELERATOR DISTRIBUTOR OR NOZZLE IN CIRCUMFERENTIAL WALL OF FLEXIBLE SUPPLY LINE With flexible or articulated flow line section Insert at terminus forms plural streams | |
