Abstract

"ACIONADOR HIDRáULICO". O objetivo tem sido prover um acionador hidráulico simplificado e aperfeiçoado na forma de um cilindro do tipo pistão hidráulico (10) proposto para uso embaixo da água ou em outros ambientes, em que o acionador é exposto à elevada pressão de ambiente. O acionador compreende um elemento de exercer força na forma de um pistão (14), formando uma parede divisória móvel entre duas câmaras (24, 26). Esse elemento de exercer força, o pistão, é acionado em uma das duas direções opostas, quando prevalecem pressões diferentes nas duas câmaras (24, 26). De acordo com a invenção, cada uma das duas câmaras (24, 26) é para permitir a evacuação, visto que pelo menos uma câmara, a primeira câmara (24), é para ser provida com uma entrada (36) com uma válvula de fechar (38) disposta nela, e em contato com o meio ambiente. Por uma entrada aberta (36) a água ou outro meio circundante é admitido em uma primeira câmara (24) e aciona o pistão (14) na dita segunda câmara (26) evacuada contra a ação de uma mola de retorno (28).
