Abstract

CILINDRO COMBINADO DE FREIO DE SERVIçO E FREIO DE MOLA ACUMULADORA A presente invenção refere-se a um combinado de freio de serviço e freio de mola acumuladora (1) para instalações de freio de veículos, especialmente veículos utilitários, com um êmbolo de freio de serviço e de freio de mola acumuladora (4,8) conduzido dentro de uma caixa (10) comum aos dois cilindras (2, 6), sendo que o êmbolo de freio de mola acumuladora (8) está solicitado por pelo menos uma mola acumuladora (28) e apresenta um diâmetro externo maior do que o êmbolo de freio de serviço (4). A invenção prevê que o êmbolo de freio de mola acumuladora (8) seja um êmbolo anular e pelo menos uma parte de sua haste configurada como tubo de êmbolo (24) abarque o êmbolo de freio de serviço (4) e forme para ele uma face de serviço e vedação radialmente externa.
