Abstract

Le corps de ce robinet présente une forme générale en Venturi, mais est asymétrique. L'obturateur, du type tournant, est monté entre une entrée 32 dont les parois sont fortement divergentes et une sortie 34, qui est beaucoup plus longue et dont les parois 36 divergent plus lentement. L'angle du diffuseur conique équivalent à celui formé par la sortie du robinet est au plus de 15 degrés tandis que le rapport entre la surface de détente, à l'extrémité des parois divergent lentement, et la surface réelle de sortie est de préférence de 75 %.The body of this valve has a general Venturi shape, but is asymmetrical. The shutter, of the rotating type, is mounted between an inlet 32, the walls of which are strongly divergent, and an outlet 34, which is much longer and the walls 36 of which diverge more slowly. The angle of the conical diffuser equivalent to that formed by the outlet of the valve is at most 15 degrees while the ratio between the expansion area, at the end of the walls diverge slowly, and the actual outlet area is preferably 75%.
