Abstract

"APARELHO E UNIDADE DE FRENAGEM PARA UM SISTEMA DE FRENAGEM PNEUMáTICO". Uma válvula de retenção dupla (70) está integralmente localizada em uma câmara de freio com mola, para reduzir a tubulação associada a um sistema de freio pneumático. Uma anticomposição é provida, em virtude de uma pressão de orientação de aproximadamente 138 a 207 kPa entre uma câmara de pressão (52) de um atuador de serviço (44) e uma câmara de operação (66) de um atuador de estacionamento / emergência (46). Da mesma forma, um rolamento para trás do veículo é considerado, uma vez que a transição de uma aplicação de serviço para uma aplicação de estacionamento assegura que os freios de serviço estejam suficientemente aplicados, até que o freio com mola se torne operativo.
