Abstract

"SISTEMA COMBINADO DE VáLVULAS PARA ATUADOR DE FREIO DE MOLA" Um atuador de freio de mola aprimorado inclui uma carcaça de válvula aprimorada (32), que incorpora pontos de teste de pressão (40) no suprimento de ar, e incorpora, além disso, uma válvula de anticompoundagem (42). Mediante a incorporação da válvula de anticompoundagem (42) e de pontos de teste (40) diretamente no distribuidor de válvulas (41), o atuador de freio de mola de acordo com a invenção reduz o número de peças separadas. A válvula de anticompoundagem é operável para assegurar que não haverá compoundagem da força de frenagem.
