Abstract

"SISTEMA DE VáLVULA DE CONTROLE DE FLUIDO". é apresentado um sistema de válvula de controle de fluido (30, 130) para controlar o fluxo de fluido hidráulico fornecido a e descarregado de um acionador (210) que tem um primeiro e segundo orifícios e acionador (214, 215), o qual compreende: uma carcaça de válvula (40, 140) que tem uma câmara detectora de pressão (77, 177) para detectar a pressão do fluido hidráulico introduzido nela e um orifício de pressão (43, 153) para introduzir um fluido hidráulico; um carretel de válvula (60, 160) alojado, de modo a poder mover-se em sentido axial, na carcaça de válvula (40, 140); meios acionadores de carretel de válvula (70, 170) que tem o carretel de válvula (60,160) movido em sentido axial e incluindo um motor de força (71, 171), uma haste de pistão (72, 172) que tem o carretel de válvula (60, 160) alojado, de modo a poder deslizar, nela e acionado pelo motor de força (71, 171), e um pistão fixo (75, 175) firmemente ligado com a haste de pistão (72, 172); e meios resilientemente impulsores (90, 190) para impelir resilientemente o carretel de válvula (60,160) ao longo do eixo geométrico central (41a, 141c) da carcaça de válvula (40, 140), o carretel de válvula (60, 160) sendo impelido pela pressão hidráulica do fluido hidráulico na câmara detectora de pressão (77, 177) e no meio resilientemente impulsor (90, 190) de modo a assumir posições operacionais que consistem em posições operacionais normais, nas quais a pressão hidráulica do fluido hidráulico na câmara detectora de pressão (77, 177) é maior que a força resiliente do meio resilientemente impulsor (90, 190), de modo a ter o carretel de válvula (60, 160) movido em sentido axial juntamente com a haste de pistão (72, 172) do meio acionador de carretel de válvula (70, 170) e uma posição operacional anormal, na qual a pressão hidráulica na câmara detectora de pressão (77, 177) é reduzida até que o meio resilientemente impulsor (90, 190) comece a impelir e mover axialmente o carretel de válvula (60, 160) na direção do
