Abstract

"INTENSIFICADOR PARA FRENAGEM DE EMERGêNCIA QUE COMPREENDE DISPOSITIVOS DE FECHAMENTO QUE ENVOLVEM UM OBSTáCULO RADIAL". A invenção refere-se a um intensificador de freio pneumático (10) para um veículo motorizado, do tipo que compreende um dispositivo de embreagem unidirecional que compreende uma bucha axial (58) que desliza em um êmbolo (46), e dispositivos de fechamento axialmente da bucha (58) que podem, quando uma força de entrada é aplicada em uma razão determinada a uma haste de operação (38) presa a um êmbolo (46), fechar a bucha (58) em uma posição axial, sendo que fecha o pistão (22) independentemente da haste de operação (38), caracterizado pelo fato de que o dispositivo de embreagem unidirecional compreende dispositivos de obstáculo radial, especialmente, um elemento (72), pelo menos, uma parte anular do mesmo envolve a bucha (60) e é retornado elasticamente em uma direção substancialmente radial em direção à periferia da bucha (60) para que, quando a força de entrada é aplicada na razão determinada, se aloje em um sulco (74) da bucha (60) e feche o apalpador (52).
