A reactive speed hump (2) includes a fluid flow control valve assembly (4). A first valve (18, 20, 21) is naturally open and a second valve (10, 14, 15, 16, 17), naturally closed. Application of fluid pressure on the control valve assembly below a first lower threshold level or above a second higher threshold level allows a flow of fluid from the inlet to the outlet, but an application of fluid pressure on the control valve between said first and second threshold levels allows substantially no fluid to flow between the inlet (7) and the outlet (9).
L'invention concerne un ralentisseur dos d'âne allongé réactif (2) comportant un assemblage de soupape de régulation de débit de fluide (4). Une première soupape (18, 20, 21) est naturellement ouverte tandis qu'une seconde soupape (10, 14, 15, 16, 17) est naturellement fermée. L'application d'une pression par fluide sur l'assemblage de soupape en-deça d'un premier niveau de seuil inférieur ou au-dessus d'un second niveau de seuil supérieur permet à un flux de fluide de passer de l'entrée jusqu'à la sortie, cependant une application de pression par fluide sur la soupape de régulation entre lesdits premiers et seconds niveaux de seuil empêche quasiment tout fluide de cheminer entre l'entrée (7) et la sortie (9).
