Abstract

DISPOSITIVO DE VENTILAçãO PARA UM ACUMULADOR A MOLA E CILINDRO DE FREIO OPERATIVO COMBINADO. O dispositivo de ventilação compreende uma válvula (39, 44, 49, 50, 40, 34, 14, 15, 37, 48) disposta em um acumulador a mola e cilindro de freio operativo combinado (1, 2) e, através da despressurização da câmara do meio de pressão (4) no cilindro de freio com acumulador a mola (1), é realizada uma ventilação da câmara do acumulador a mola (9) do cilindro de freio com acumulador a mola (1), a partir da camada do meio de pressão (22) do cilindro de freio operativo (2) De acordo com a invenção, as propriedades de fluxo da válvula (39, 44, 49, 50, 40, 34, 14, 15, 37) podem ser melhoradas, em que uma câmara (48) é instalada na lateral da válvula (39, 44, 49, 50, 40, 34, 14, 15, 37), conecta a primeira conexão operativa (14) na câmara (48) e, assim, na segunda conexão operativa (34), disposta axialmente no lado frontal da válvula, por meio de uma passagem (43, 42) prevista no pistão de válvula (39, 44)
