Abstract

"BOOSTER DE FREIO PNEUMáTICO". Sendo que a presente invenção refere-se a um booster de freio pneumático que consiste de um envelope onde uma saia (2) desliza de uma forma vedada, um pistão pneumático (8) firmemente fixo à saia, uma válvula de três vias (20) ativada por uma barra de controle (22) operada em uma primeira extremidade por um pedal, um êmbolo (32) montado em uma segunda extremidade longitudinal que está no lado oposto e montado de forma deslizável no corpo do pistão, a barra de controle e o êmbolo formando um controle de freio (33), caracterizado em que o tal booster consiste de meios (68) de abafar o movimento relativo e em particular oscilatório entre o controle de freio (33) e o pistão pneumático (8). Esta invenção se aplica principalmente a indústria de freios para veículos particulares.
