Abstract

UNIDADE DE CáMBIO Em uma unidade de câmbio (1) para uma transmissão de veículo com válvulas, que estão unida entre si por uma tubulação de adução de pressão (58) e uma tubulação de descarga de pressão (60) e associadas a uma câmara de câmbio (10) de um cilindro de câmbio (2). A câmara de câmbio (10) do cilindro de câmbio (2) apresenta ao menos uma válvula de abertura (26) e ao menos uma válvula de fechamento (28). Por válvulas adicionais (62,64,66,68) a tubulação de adução de pressão (58) e tubulação de descarga de pressão (60) podem ser separadamente fechadas, abertas, bloqueadas e/ou trocadas.
