Abstract

"BOOSTER PNEUMáTICO DE FREIO ESPECIALMENTE PARA UM AUTOMOVEL". Constituindo um disco de reação (30) interposto entre um êmbolo (28) carregado por uma barra de controle movimentada pelo pedal de freio e a barra de impulsão (32) atuando sobre o pistão primário de um cilindro mestre tanden, o disco de reação (30) sendo alojado dentro de uma peça metálica anular (36) que coopera com uma rolha (50) da barra de impulsão (32) por intermédio de um elemento de expansão térmica (48) projetado para compensar pela expansão térmica do disco de reação (30) e seu efeito sobre um ponto de mudança na relação de assistência.
