CA 2336053

This invention is a massaging system having at least a pair of fluid inflatable chambers (21, 22), and a fluidic switch (10) alternately connecting the at least a pair of fluid-inflatable chambers (21, 22) to a source of fluid (17) under pressure. The fluidic switch (10) is a crossover type fluid switch having a switching chamber (11) having two side walls (13, 14) in which fluid from the source (17) is switched from one side wall of the switching chamber to the other side of the switching chamber, is sensitive to load on the fluid inflatable chambers (21, 22), respectively, and vented passageways (19, 20) coupling the inflatable chambers (21, 22) to the switch.

L'invention concerne un dispositif de massage comprenant au moins deux chambres (21 et 22) conçues pour contenir un liquide; et un commutateur (10) de fluide reliant alternativement lesdites chambres (21 et 22) à une source de fluide (17) sous pression. Ledit commutateur (10) est un commutateur de fluide de type à aiguillage de liaison et il comprend une chambre de commutation (11) présentant deux parois latérales (13 et 14) dans laquelle le fluide provenant de la source (17) est commuté d'une paroi latérale à l'autre. De plus, ledit commutateur permet d'une part, de charger lesdites chambres (21 et 22) et, d'autre part, de ventiler les passages (19 et 20) reliant ces mêmes chambres (21 et 22) au commutateur.
