DEVICE WITH SPRAY NOZZLE FOR STATIONARY SHOWERS AND SHOWERS WITH FLEXIBLE HOSE Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: in device with spray nozzle for stationary showers with flexible hose the deflecting device is made in the form of central axis with peripheral blades coaxially disposed in inner chamber being the first one on the move. The device is equipped with bushing tightly screwed on pipeline end and output perforated plate located in front of sprayer and mounted forming the front face end of coupling. The first inner chamber is placed in bushing. Each blade of deflecting device is made with lower incision for grouping several whirling water jets along the central axis. The latter has peak on the end for collecting water jets into single central whirling jet. The central axis has longitudinal hole for free passing of water flow. Output perforated plate has central hole surrounded by peripheral holes whose diameter is less than that of central hole. Central hole can have round or elongated shape. The bushing is made with channelings whose hollows are disposed forming annular grooves. The coupling has circular tooth mounted to be placed in one of annular grooves during the coupling displacement along bushing. The device can also be equipped with member having circular tooth and the bushing can have helical thread having hollows in order to place the circular tooth of member in one of them during the coupling displacement along bushing. Besides, the device has means of filtration of foreign matters. It is made as metallic net serving as thickening gasket between pipeline and bushing. EFFECT: enhanced efficiency of sprinklers. 8 cl, 6 dwg
