Title
(EN) REVERSIBLE INFLATION SYSTEM
(FR) SYSTEME DE GONFLAGE REVERSIBLE
Abstract
(EN)
A reversible inflation system allowing a single pump to be used for both inflation and deflation of the air bladder. The present embodiment of the inflation system includes a motor (60) and an impeller (74) located within a housing (28) having a diaphragm valve (47) and a slide (67). Presently, the slide determines the direction of fluid flow through the housing, so that in a first position, the system causes fluid to flow into the bladder, and in a second position, the system causes fluid to flow out of the bladder.
(FR)
Cette invention concerne un système de gonflage réversible permettant d'utiliser une seule pompe pour le gonflage et le dégonflage d'une vessie à air. Dans le présent mode de réalisation, ledit système de gonflage comprend un moteur (60) et un rotor (74) se trouvant dans un corps (28) doté d’une vanne à membrane (47) et d’un guide (67). Le guide détermine le sens d’écoulement du fluide à travers le corps de sorte que, dans une première position, le système entraîne l’entrée du fluide dans la vessie et, dans une seconde position, le système entraîne la sortie du fluide de la vessie.
