Abstract

MÁQUINA DE TRABALHO. Uma máquina de trabalho inclui um circuito hidráulico para uso com um acessório configurado para operar usando um de um fluxo unidirecional e um fluxo bidirecional através do acessório. Um interruptor de seleção de modo habilitado por operador se conecta operativamente a um controlador. Um circuito elétrico inclui o interruptor de seleção de modo habilitado por operador e um segundo interruptor habilitado por operador. Uma primeira válvula de controle está em comunicação fluída com o acessório. Em resposta ao interruptor de seleção de modo ser atuado pelo operador para uma configuração de modo bidirecional, a primeira válvula de controle via o controlador é atuável para uma das posições bidirecionais, energia elétrica ficando indisponível para o segundo interruptor habilitado por operador do circuito elétrico. Em resposta ao interruptor de seleção de modo ser atuado pelo operador para uma configuração de modo unidirecional, a primeira válvula de controle via o controlador prende a primeira válvula de controle na posição unidirecional, e energia elétrica é fornecida para o segundo interruptor habilitado por operador do circuito elétrico.
