Abstract

"BOCAL DE EXAUSTãO VARIáVEL COM CAME". Trata-se de um bocal de exaustão (38) que inclui um duto de exaustão (36) com uma saída (46) e uma série de aberturas radiais (48) a montante a partir da mesma. Um quadro radial (58) circunda o duto (36) a montante das aberturas (48). Uma série de flapes (56) são articulados para o quadro (58) para seletivamente cobrir e descobrir as aberturas (48) para controlar o fluxo de exaustão descarregado através das mesmas. Uma barra de união arqueada (66) circunda o duto (36) adjacente ao quadro (58) e inclui os seguidores de came separados de forma circunferencial (68) se engatando com os cames correspondentes (64) afixados com os flapes. Um acionador (70) é unido com a barra (66) para rotação seletiva da mesma entre a primeira e segunda direções opostas para abrir e fechar em forma de pivó os flapes em cima das aberturas (48).
