Abstract

Un robinet de chasse comporte un corps ayant une entrée et une sortie et un siège entre l'entrée et la sortie. Le siège définit une ouverture traversante. Un couvercle est fixé au corps. Un piston est en prise avec le siège et est mobile à l'intérieur du corps et du couvercle dans la mesure permise par une butée formée dans le corps ou le couvercle. Le piston comprend une partie de guidage s'étendant au travers de l'ouverture du siège et en aval de celui-ci. La partie de guidage comporte des nervures et une jupe. La longueur axiale des nervures et de la jupe est supérieure à la course disponible du piston, de sorte que les passages d'écoulement à travers l'ouverture du siège sont en tout temps définis par la jupe et les nervures.
