Abstract

UNIDADE DE FRENAGEM ANTITRAVAMENTO PARA UM SISTEMA DE FRENAGEM HIDRÁULICA, PARTICULARMENTE DE UMA BICICLETA, E UNIDADE DE VÁLVULA. Uma unidade de frenagem antitravamento (13) compreende um único solenoide de atuação (31) agindo em um pistão (40) de uma unidade de válvula (30) associada. O solenoide move o pistão dentro de uma câmara primária (38) a qual está em comunicação fluida com uma pinça de freio (14). O movimento do pistão fecha uma passagem de desvio (50), formada dentro da unidade de válvula, que normalmente conecta um cilindro mestre (12) à pinça de freio (14). Ao fechar a passagem de desvio (50), o acúmulo de pressão que age na pinça é interrompido. Simultaneamente, o mesmo movimento de atuação do pistão (40) abre uma passagem de escoamento (51) dentro da unidade de válvula, permitindo que o fluido de freio seja ventilado a partir da câmara primária (38) para uma câmara de expansão (39). A câmara de expansão fornece um volume aumentado para o fluido de freio contido entre a unidade de válvula (30) e a pinça de freio, diminuindo assim a pressão do fluido de freio agindo na pinça.
