Title
(EN) IMPROVEMENTS IN VACUUM CLEANING APPLIANCES
(FR) AMELIORATIONS A DES ASPIRATEURS
Abstract
(EN)
A vacuum cleaning apparatus with an improved air control valve (22) for directing air flow to a passageway (11) in a casing either from a cleaning head (2) or a hose section (6). In the preferred form the valve rotates to provide internal passages to the air passageway in the casing. The apparatus is particularly adapted as a vacuum cleaning appliance.
(FR)
Aspirateur pourvu d'une vanne améliorée de commande d'air (22) permettant de diriger l'écoulement d'air vers un passage (11) dans une enceinte soit à partir d'une tête de nettoyage (2), soit à partir d'une section de tuyau. Dans le mode préféré de réalisation la vanne tourne pour former des cheminements internes pour le passage d'air dans l'enceinte. Le dispositif est conçu notamment pour des aspirateurs.
