Title (EN) COMPACT PRESSURE BALANCED ROTARY VALVE
(FR) VANNE ROTATIVE COMPACTE ÉQUILIBRÉE EN PRESSION
Abstract: front page image
(EN)A pressure balanced rotary valve can be made more compact if the ports on the stator within can be located on a port pitch circle of smaller diameter. In certain circumstances for rotary valves used in pressure swing adsorption devices, it is acceptable for the spacing between the ports to be made smaller than the ports themselves. In a rotary valve comprising variable loading means (e.g. pistons) and fixed loading means (e.g. springs), this can involve reducing the piston size and increasing the load provided by the springs.
(FR)Selon l'invention, une vanne rotative équilibrée en pression peut être rendue plus compacte si les orifices du stator intérieur sont ménagés sur un cercle primitif d’orifices de plus petit diamètre. Dans certaines circonstances, pour des vannes rotatives utilisées dans des dispositifs d’absorption d’oscillations de pression, il est acceptable que l’espacement entre les orifices soit rendu plus petit que les orifices eux-mêmes. Dans une vanne rotative comportant des moyens de chargement variable (par ex. des pistons) et des moyens de chargement fixe (par ex. des ressorts), cela peut impliquer une réduction de la taille des pistons et une augmentation de l’effort exercé par les ressorts.
