Abstract

"SISTEMA HIDRáULICO, EM PARTICULAR, PARA VEìCULOS AUTOMOTORES". A presente invenção refere-se a um sistema hidráulico, em partIcular, para veículos automotores, compreendendo um cilindro transmissor, um cilindro receptor e um condutor do meio de pressão que liga esses cilindros, é obtido um aumento de pressão de custo mais baixo, pelo fato de que, o sistema hidráulico compreende uma bomba, com uma entrada e uma saída e uma válvula, que estão dispostas no condutor do meio de pressão entre o cilindro transmissor e o cilindro receptor, sendo que, a válvula tem uma primeira posição da válvula, na qual o cilindro transmissor 4 o cilindro receptor estão ligados diretamente entre si, bem como, uma segunda posição da válvula, na qual o cilindro transmissor e o cilindro receptor estão ligados entre si através da bomba.
