Abstract

"PROCESSO PARA ATIVAçãO DE UM EQUIPAMENTO DE SUPRIMENTO DE PRESSãO EM UM CIRCUITO HIDRáULICO". No âmbito do processo para ativação de um equipamento de suprimento de pressão em um circuito hidráulico, especialmente em um circuito hidráulico de uma transmissão automática, que abrange uma bomba hidráulica, uma válvula de superpressão e um consumidor, sendo que a bomba hidráulica é ativada quando a pressão do sistema cai abaixo de um determinado valor limiar inferior e é desligada quando um determinado valor limiar superior da pressão do sistema é atingido ou ultrapassado, para o caso de os dados da pressão do sistema não estarem disponíveis, a pressão do sistema atual é calculada.
