Abstract
"CONJUNTO REGULADOR DE PRESSãO PNEUMáTICA PROPORCIONAL, E, CIRCUITO DE CONTROLE ELETRôNICO DO MESMO". Um conjunto regulador de pressão pneumática proporcional (10) que tem um corpo principal (12) com uma primeira entrada (50) adaptada para comunicação fluida com um suprimento de pressão pneumática positiva, uma segunda entrada (52) adaptada para comunicação fluida com um suprimento de pressão pneumática negativa, uma saída (54) adaptada para comunicação fluida com um dispositivo atuado pneumaticamente, e um orifício de exaustão (56). Uma válvula de regulagem de enchimento (14) é incluída, a qual é adaptada para regular o suprimento de pressão positiva. Uma válvula de regulagem de vácuo (20) é incluída, a qual é adaptada para regular o suprimento de pressão negativa. Uma válvula de exaustão (16) é incluída, a qual é operável para aliviar pressão pela saída (54). Um conjunto de circuitos de controle (24) é também provido, o qual é adaptado para receber um sinal de comando e um sinal de realimentação e para regular o valor de pressão pneumática positiva através da válvula de regulagem de enchimento (14) ou o valor de pressão pneumática negativa através da válvula de regulagem de vácuo (20) em resposta ao sinal de realimentação.
