Title (EN) FLUID SWITCHING VALVES
(FR) VANNES DE COMMUTATION DE FLUIDE
Abstract: front page image
(EN)A fluid switching valve includes a first valve element (e.g., a stator) that has a plurality of first fluid-conveying features (e.g., ports), and a second valve element (e.g., a rotor) that has one or more second fluid-conveying features (e.g., fluid conduits in the form of grooves). The second valve element is movable, relative to the first valve element, between a plurality of discrete positions such that, in each of the discrete positions, at least one of the one or more second fluid-conveying features overlaps with multiple ones of the first fluid conveying features to provide for fluid communication therebetween. At least one of the first valve element and the second valve element includes a recess. The recess serves to reduce wear between the first valve element and the second valve element. The recess is arranged such that it does not overlap with any of the first fluid-conveying features or any of the second fluid-conveying features when the rotor is in any of the discrete positions.
(FR)L'invention porte sur des vannes de commutation de fluide qui comprennent un premier élément de vanne (par exemple un stator), qui possède une pluralité de premières formations de transport de fluide (par exemple des orifices), et un deuxième élément de vanne (par exemple un rotor), qui possède une ou plusieurs deuxièmes formations de transport de fluide (par exemple des conduits de fluide sous la forme de rainures). Le deuxième élément de vanne est mobile, par rapport au premier élément de vanne, entre plusieurs positions discrètes, de sorte que, dans chacune des positions discrètes, au moins l'une de la ou des deuxièmes formations de transport de fluide chevauche de multiples formations parmi les formations de transport de fluide pour établir une communication fluidique entre elles. Au moins l'un du premier élément de vanne et du second élément de vanne présente un évidement. L'évidement sert à réduire l'usure entre le premier élément de vanne et le second élément de vanne. L'évidement est disposé de sorte qu'il ne chevauche pas l'une quelconque des premières formations de transport de fluide ni l'une quelconque des deuxièmes formations de transport de fluide lorsque le rotor est dans l'une quelconque des positions discrètes.
