Abstract

um dispositivo (100) para manutenção de uma pressão hidráulica (p), a qual é controlável através de um gerador de pressão (50), compreende uma entrada (110) para acoplamento ao gerador de pressão (50); uma saída (120) para provisão da pressão hidráulica (p); pelo menos uma primeira válvula de retenção (131) e um dispositivo de ligação (140) entre a entrada (110) e a saída (120). a primeira válvula de retenção (131) está configurada para abrir um caminho de fluxo da entrada (110) para a saída (120) quando se ultrapassa uma primeira pressão de abertura (p1) e para impedir um fluxo no sentido contrário. o dispositivo de ligação (140) está configurado para manter uma pressão hidráulica (p) na saída (120) quando uma pressão (p0) gerada pelo gerador de pressão (50) for superior à pressão de ligação (ps), e impedir a pressão hidráulica (p) na saída (120) quando a uma pressão (p0) gerada pelo gerador de pressão (50) for inferior à pressão de ligação (ps), sendo que a pressão de ligação (ps) é inferior à pressão de abertura (p1).
