Title
(EN) BLOWER FOR BREATHING APPARATUS
(FR) SOUFFLANTE POUR APPAREIL RESPIRATOIRE
Abstract
(EN) A blower for a breathing apparatus comprising a housing with an inlet and an outlet, a motor within the housing for rotating an impeller, a diffuser within the housing between the impeller and outlet, the diffuser comprising a plate with diffuser elements, the diffuser elements being arranged in cascades on the plate, each cascade comprising a series of diffuser elements and the diffuser comprising one or more circumferential rings with circumferential diffuser elements arranged on the rings.
(FR) L'invention porte sur une soufflante pour un appareil respiratoire, laquelle soufflante comprend un boîtier doté d'une entrée et d'une sortie, un moteur à l'intérieur du boîtier pour faire tourner une hélice, un diffuseur à l'intérieur du boîtier entre l'hélice la sortie, le diffuseur comprenant une plaque dotée d'éléments diffuseurs, les éléments diffuseurs étant disposés en cascade sur la plaque, chaque cascade comprenant une série d'éléments diffuseurs, et le diffuseur comprenant une ou plusieurs bagues périphériques, des éléments diffuseurs périphériques étant agencés sur les bagues.
