Abstract

sistema óleo-hidráulico para mover um portão trata-se de um sistema óleo-hidráulico para mover um portão, o qual compreende um cilindro óleo-hidráulico de atuação dupla (11), destinado a conectar-se cinematicamente ao portão para movê-lo, e uma bomba eletro-hidráulica (12), para alimentar e acionar o cilindro mediante um comando. uma válvula de comutação (13) interconecta o cilindro (11) alternadamente à bomba (12) ou a um tanque (14) com fluido óleo-hidráulico. em condições de repouso, a válvula (13)conecta o clindro (11) ao tanque (14) a fim de permitir o deslocamento manual livre do portão conectado ao cilindro e, além disso, a vávula (13) é controlada automaticamente, por variações de pressão no sistema produzidas pelo acionamento da bomba (12), a fim de desconectar o cilindro (11) do tanque (14) e conectá-lo à bomba (12).
