Abstract

ventilador, em particular ventilador radial ou diagonal. a presente invenção refere-se a um ventilador (1), em particular ventilador radial ou diagonal, com um motor (4), um impulsor (3) acionado pelo motor (4), um bocal de entrada (5) e uma placa de bocal (2) que se estende ao redor do bocal de entrada (5), sendo que o impulsor (3) consiste essencialmente em um disco inferior (10), um disco superior (8) e diversas pás (9) que se estendem entre eles, a placa de bocal (2) apresenta uma borda dobrada para o lado da pressão e o disco superior (8) é arredondado em sua borda externa em direção ao lado de sucção, e sendo que a parte dobrada (6) da placa de bocal (2) e o arredondamento do disco superior (8) são moldados e dimensionados de modo que o fluxo de saída que flui para fora do impulsor (3) próximo ao disco superior interaja com o dobramento guiado da placa de bocal (2).
