Abstract

um sistema de bomba hidráulica inclui um sistema de controle de bomba operável para reduzir a corrente elétrica necessária na partida da bomba e reduzir o torque de partida para a bomba. o sistema de controle de bomba pode incluir uma folga entre uma sede de mola e um carretel de válvula, de modo que o carretel de válvula não precise ultrapassar uma força de desvio de uma placa oscilante quando a placa oscilante mudar de sua posição de deslocamento máximo para a sua posição neutra.
