Abstract
"VáLVULA DE ìMã DE TRêS ESTADOS". Uma válvula de imã de três estados para controle de escoamento de fluido que pode ser encaixada com uma fonte de pressão de fluido para conexão da válvula de imã de três estados a uma fonte de pressão de fluido. A válvula de ímã de três estados também tem uma válvula solenóide de piloto de aplicação que tem uma conexão de fluido para uma fonte de pressão de fluido e é eletricamente conectável a um módulo de controle. A válvula de imã de três estados ainda tem uma válvula solenóide de aplicação que tem uma conexão de fluido para uma fonte de pressão de fluido e para uma válvula solenóide de piloto de aplicação e um dispositivo de frenagem. Artigo absorvente válvula solenóide de aplicação também é eletricamente conectável a um módulo de controle. A válvula solenóide de aplicação é capaz de iniciar uma aplicação de frenagem mediante o recebimento de um sinal de fluido da válvula solenóide de piloto de aplicação e um sinal elétrico de um módulo de controle. A válvula de imã de três estados ainda tem uma válvula solenóide de piloto de liberação que tem uma conexão de fluido para uma fonte de pressão de fluido e para a válvula solenóide de aplicação e é eletricamente conectável a um módulo de controle. A válvula de imã de três estados também tem uma válvula solenóide de liberação que tem uma conexão de fluido para uma exaustão para a atmosfera e para a válvula solenóide de aplicação e para a válvula solenóide de piloto de liberação e para um dispositivo de frenagem. A válvula solenóide de liberação é eletricamente conectável a um módulo de controle. A válvula solenóide de liberação é capaz de exaurir a pressão de fluido para a atmosfera mediante o recebimento de um sinal de pressão de fluido da válvula solenóide de piloto de liberação e um sinal elétrico de um módulo de controle, desse modo exaurindo-se a pressão de fluido a partir do referido dispositivo de frenagem.
