Abstract

SISTEMA ATUADOR E MÉTODO PARA COMBINAR SAÍDAS DE UMA PLURALIDADE DE BOMBAS DE FLUIDO. Um método para combinar as saídas de uma pluralidade de bombas de fluido inclui receber um sinal de entrada a partir de um dispositivo de entrada. 0 sinal de entrada é adaptado para controlar uma função de um veiculo de trabalho. Um sinal de atuação é enviado para um primeiro dispositivo de controle de direção de um primeiro conjunto atuador. O primeiro conjunto atuador esta em comunicação fluida seletiva com um primeiro conjunto de bomba. Uma posição de uma segunda válvula de controle de direção de um segundo conjunto atuador é recebida. O segundo conjunto atuador está em comunicação fluida seletiva com um segundo conjunto de bomba. Uma válvula seletora que está em comunicação fluida com uma cavidade de um conjunto de válvula de assento axial é atuada tal que o segundo conjunto de bomba esteja em comunicação fluida com o primeiro conjunto atuador quando a segunda válvula de controle de direção estiver em uma posição neutra.
