Abstract

Patente de Invenção:<B>"FILTRO AUTOLIMPANTE PARA CIRCUITOS PNEUMáTICOS"<D>. Um filtro autolimpante para circuitos pneumáticos inclui uma placa defletora de filtragem (1) montada sobre um tambor (2) que gira de maneira uniforme, vindo o fluxo (A) do ar a ser filtrado de fora para dentro da placa defletora (1), como também uma boca de sucção (5) posicionada longitudinalmente no meio-plano vertical no ponto mais inferior da placa defletora (1) e externamente adjacente à mesma, e um tubo de ventilação (6) internamente adjacente à placa defletora (1) em uma posição exatamente oposta à boca (5), ambos a boca (5) e o tubo (6) estendendo-se ao longo do comprimento total da placa defletora de filtragem (1). O tubo (6) possui uma pluralidade de furos alinhados adequados de tal forma a emitir um jato estreito de ar de contracorrente, com incidência regulável, e a boca (5) tem a forma de uma tremonha trapezoidal com um pequeno tubo de ventilação regulável (C) em uma extremidade.
