Abstract

"SISTEMA HIDRáULICO". A presente invenção refere-se a um sistema hidráulico, especialmente para automóveis, compreendendo um cilindro mestre com uma caixa, um êmbolo disposto de modo axialmente deslocável dentro dela que delimita uma câmara de compressão cheia de líquido hidráulico e que durante o acionamento do cilindro mestre por meio de uma biela de êmbolo agindo sobre o êmbolo é deslocado axialmente, solicitando assim o líquido hidráulico com pressão, e pelo menos um elemento de vedação disposto entre a caixa e o êmbolo, compreendendo ainda um cilindro auxiliar e uma linha de agente de pressão que liga estes. A tarefa de colocar à disposição um sistema hidráulico com um cilindro mestre que em todas as condições operacionais possibilita um roncar seguro, isto é, uma compensação de pressão entre a câmara de compressão e a câmara de complementação e de ventilação, de acordo com a presente invenção, é solucionada pelo fato de que o elemento de vedação possui no lado voltado para o êmbolo pelo menos uma ranhura que se estende substancialmente em direção axial."Hydraulic system". The present invention relates to a hydraulic system, especially for automobiles, comprising a master cylinder with a housing, an axially displaceable piston disposed therein which delimits a hydraulic fluid-filled compression chamber and which during actuation of the master cylinder by means of a piston rod acting on the piston is displaced axially, thereby requesting the hydraulic fluid with pressure, and at least one sealing element disposed between the housing and the piston, further comprising an auxiliary cylinder and a pressure agent line that connects these. The task of providing a hydraulic system with a master cylinder which under all operating conditions enables safe snoring, ie a pressure compensation between the compression chamber and the supplementation and ventilation chamber in accordance with this The invention is solved by the fact that the sealing member has on the piston-facing side at least one groove extending substantially axially.
