Abstract

VENTILADOR COM ELEMENTOS DE ATENUAÇÃO E DE VEDAÇÃO ENTRE PARTES DE CARCAÇA DIFERENTES. A presente invenção refere-se a um compressor (1) para transporte de uma corrente de ar e/ou gás, bem como a um aparelho de ventilação ou anestesia com um compressor (1) desse tipo. O compressor (1) dispõe de uma carcaça, em cujo espaço interior de carcaça (3) está disposta uma roda de compressor (6) montada de modo rotativo e conectada através de um eixo de acionamento (4) com um motor elétrico (5), na rotação da qual a corrente de ar e/ou gás é transportada de uma entrada (9) disposta a montante, sobre um lado de aspiração (7) da roda de compressor (6), por um canal de corrente (11), para uma saída (9) disposta a jusante, sobre um lado de pressão (8) da roda de compressor (6). A solução técnica descrita distingue-se pelo fato de que a roda de compressor (6) disposta no espaço interno de carcaça (3), está circundada, pelo menos em áreas, pela carcaça, realizada como carcaça coletora (2) para a corrente de ar e/ou gás, e por um elemento de tampa (12), que está disposto, pelo menos parcialmente, sobre o lado de aspiração (7) da roda de compressor (6) e separado, pelo menos em parte, por uma fenda (13) da roda de compressor (6).
