Title (EN) IMPROVEMENTS IN, OR RELATING TO, SPRAY HEADS
(FR) AMÉLIORATIONS APPORTÉES À, OU ASSOCIÉES À, DES TÊTES DE PULVÉRISATION
Abstract:
(EN) A spray head adapted for connection to a supply of fluid. The head includes a body to receive the supply of fluid and a number of conical mixing volumes, in fluid connection with the body and supply of fluid, each conical mixing volume having an outlet. Each conical mixing volume includes at least one first inlet for a flow of fluid into the conical mixing volume at an angle to a conical axis thereof, and at least one second inlet for a flow of fluid into the conical mixing volume substantially parallel to the conical axis. There is a valve disposed upstream of the conical mixing volumes, the valve adapted to divide and vary the supply of fluid flow between the at least one first inlet and the at least one second inlet, which in turn varies the output of the fluid from the outlet of the conical mixing volumes.
(FR) L'invention concerne une tête de pulvérisation conçue pour être raccordée à une alimentation en fluide. La tête comprend un corps pour recevoir l'alimentation en fluide et un certain nombre de volumes de mélange coniques, en communication fluidique avec le corps et l'alimentation en fluide, chaque volume de mélange conique ayant une sortie. Chaque volume de mélange conique comprend au moins une première entrée pour un flux de fluide dans le volume de mélange conique à un angle par rapport à son axe conique, et au moins une seconde entrée pour un flux de fluide dans le volume de mélange conique sensiblement parallèle à l'axe conique. Une vanne est disposée en amont des volumes de mélange coniques, la vanne étant conçue pour diviser et faire varier l'alimentation en fluide entre ladite première entrée et ladite seconde entrée, qui à son tour fait varier la sortie du fluide à la sortie des volumes de mélange coniques.
