Abstract

CIRCUITO DE FILTRO EM UM SISTEMA HIDRáULICO DE VEìCULO Um sistema hidráulico de veículo tendo um circuito de lubrificação de componente, uma bomba suprindo fluido hidráulico de um depósito para um primeiro e segundo circuito de controle hidráulico inclui um circuito de filtro. O circuito de filtro inclui uma primeira saída de circuito de filtro conectada a uma entrada do circuito de lubrificação, uma linha de depósito conectada ao depósito e uma segunda saída de circuito de filtro conectada a uma entrada da bomba. Um filtro ou tela de sucção é conectado entre a linha de depósito e a segunda saída de circuito de filtro. Um filtro de desvio de sucção é conectado em série com uma válvula de desvio de sucção entre a linha de depósito e a segunda saída de circuito de filtro. Um filtro ou tela de retomo é conectado a uma saída do primeiro circuito de controle. Uma linha de retomo é conectada entre o filtro de retomo e a primeira saída de circuito de filtro. Um filtro de desvio de retomo ou tela é conectado em série com uma válvula de desvio de retomo entre uma saída do primeiro circuito de controle e a linha de retomo. Uma válvula de contrapressão sensível à pressão tem uma saída conectada à segunda saída de circuito de filtro, e tem uma entrada e uma linha piloto de sensoreamento de pressão ambas conectadas a uma saída do filtro de retomo. A válvula de contrapressão tem também um membro de válvula solicitado por uma mola para uma posição normalmente fechada e móvel para uma porção aberta em resposta à pressão na linha piloto. Um orifício está localizado na linha de retomo. Uma linha de sensoreamento de pressão tem uma extremidade conectada à linha de retomo entre o orifício e a primeira saída de circuito de filtro, e tem uma segunda extremidade conectada ao membro de válvula em oposição à linha piloto.
