Abstract

Patente de Invenção: <B>"GRUPO PISTãO-CILINDRO BLOQUEáVEL"<D>. Grupo pistão-cilindro abrangendo um cilindro que é dividido em dois compartimentos de trabalho por um pistão em uma haste de pistão, sendo que os dois compartimentos de trabalho existe uma conexão fluida é bloqueável por meio de um conjunto de válvulas que possui ao menos duas válvulas individuais alinhadas em uma carreira, tendo sempre um lado e deentrada e de saída e que abre seq³encialmente, sendo que no percurso do fluxo, entre as válvulas individuais, está integrado um conjunto estrangulador que apresenta uma redução da pressão entre o lado de saída da válvula, da primeira válvula individual na direção do lado de entrada da válvula seguinte, sendo que o conjunto estrangulador reduz a sua ação com crescente grau de abertura da primeira válvula individual e na mesma medida aumentada a sujeição da pressão da válvula individual seguinte no lado de entrada, sendo que o conjunto de válvulas apresenta duas direções de fluxo de passagem, sendo configurado de forma bloqueável.
