Patent

CA 2464723

A valve assembly (32) is provided that automatically dispenses aerosol content from a can (22) at predetermined intervals. A diaphragm (70) at least partially defines an accumulation chamber (71) that receives aerosol content from the can (22) during an accumulation phase. Once the internal pressure of the accumulation chamber (71) reaches a predetermined threshold, the diaphragm (70) flexes to initiate a spray phase, during which the aerosol content is delivered from the accumulation chamber (71) to the ambient environment. A rotatable pawl (78) provides resistive pressure and control of diaphragm movement.

L'invention concerne un ensemble valve (32) qui distribue automatiquement un aérosol d'un contenant (22) à des intervalles prédéterminés. Un diaphragme (70) définit au moins partiellement une chambre d'accumulation (71) qui reçoit le contenu aérosol du contenant (22) durant une phase d'accumulation. Une fois que la pression interne de la chambre d'accumulation (71) atteint un seuil prédéterminé, le diaphragme (70) se fléchit afin de commencer une phase de pulvérisation durant laquelle le contenu d'aérosol est délivré de la chambre d'accumulation dans l'environnement ambiant. Un cliquet rotatif (78) offre une pression résistante et permet de commander le mouvement du diaphragme.
