Title (EN) DIRT SEPARATOR FOR A VACUUM CLEANER
(FR) SÉPARATEUR DE SALETÉ POUR ASPIRATEUR
Abstract:
(EN) A dirt separator for a vacuum cleaner comprises a chamber having an inlet through which dirt-laden fluid enters the chamber and an outlet through which cleansed fluid exits the chamber; and a disc located at the outlet, the disc being arranged to rotate about a rotational axis, and comprising holes running from an upstream face to a downstream face through which the cleansed fluid passes. Each hole has a tapered portion which narrows from an upstream end to a downstream end thereof.
(FR) Un séparateur de saleté pour un aspirateur comprend une chambre ayant une entrée à travers laquelle un fluide chargé de saleté pénètre dans la chambre et une sortie à travers laquelle le fluide purifié sort de la chambre; et un disque situé au niveau de la sortie, le disque étant agencé pour tourner autour d'un axe de rotation, et comprenant des trous s'étendant d'une face amont à une face aval à travers laquelle passe le fluide purifié. Chaque trou a une partie effilée qui se rétrécit d'une extrémité amont à une extrémité aval de celui-ci.
