Abstract

"SISTEMA HIDRáULICO". Em um sistema hidráulico, especialmente para automóveis, compreendendo um cilindro principal com uma caixa, um êmbolo axialmente deslocável disposto nela que delimita uma câmara de compressão cheia de líquido hidráulico e que em caso de acionamento do cilindro principal é deslocado axialmente por meio de uma biela de êmbolo que age sobre o êmbolo, solicitando assim com pressão o líquido hidráulico, e pelo menos um elemento de vedação disposto entre a caixa e o êmbolo, e compreendendo ainda um cilindro auxiliar, e uma linha de agente de compressão ligando estes, a tarefa de indicar um sistema hidráulico que não é danificado em caso de excesso de carga é solucionada, colocando-se no sistema hidráulico uma válvula de controle de pressão que limita a pressão no sistema hidráulico em uma pressão máxima.
