Abstract

"DISPOSITIVO DE FRENAGEM INTENSIFICADORA PARA UM VEìCULO A MOTOR". Sendo que a presente invenção consiste em um dispositivo de frenagem que compreende um cilindro principal (2), um pistão primário (3), um membro de controle manual (4), um intensificador (6) ligado ao membro de controle manual (4), e uma válvula auxiliar de emergência (VA) que compreende um pistão de reação (17) através do qual passa um controle de reação (24) que possui uma cabeça (25) localizada em uma câmara (26) que permanece entre o pistão de reação (17) e uma bucha (27) alojada também adiante em um orifício (18) do pistão primário, essa bucha (27) possui uma passagem axial (28) em que possa deslizar um pistão rápido (29), a extremidade posterior da qual se forma com a cabeça (25), uma válvula (36) capaz de fechar a entrada em uma passagem (30) no pistão rápido. O dispositivo compreende dispositivos (E) que compreendem a bucha (27) a ser montada, de maneira tal que ela possa deslizar, para limitar a diferença de pressão entre a câmara (26) e a zona (18a) do orifício situado adiante da bucha, a um valor abaixo do qual possa fazer com que a válvula (36) se abra.
