Title (EN) FOUR WAY VALVE
(FR) SOUPAPE A QUATRE VOIES
Abstract: front page image
(EN)A four way valve which is relatively easy to manufacture and which is smaller than conventional four way valves for a given bore size or flowing capacity. The valve can be formed utilizing a closure (18) having a pair of intersecting bores, with a separator (36) provided within the closure (18) to form two isolated passageways or flow paths (20, 24; 22, 26).
(FR)L'invention concerne une soupape à quatre voies de fabrication relativement aisée et de taille inférieure à celle des soupapes à quatre voies classiques, pour une taille d'orifice ou une capacité d'écoulement données. On peut réaliser cette soupape en utilisant une enceinte (18) dotée d'une paire d'orifices en intersection. Un séparateur (36) est prévu dans l'enceinte (18) pour former deux passages ou trajets d'écoulement isolés (20, 24; 22, 26).
