Abstract

DISPOSITIVO DE CONTROLE DE FLUIDO EQUILIBRADO POR PRESSãO A presente invenção se refere a um dispositivo de controle de fluido equilibrado por pressão. Em uma modalidade ilustrativa, o dispositivo compreende um corpo, um tampo acoplado ao corpo, uma haste de válvula operacionalmente acoplada a uma passagem posicionada no corpo, uma vedação de haste de válvula posicionada entre a haste de válvula e o tampo, no qual existe uma cavidade vedada existe acima da vedação de haste de válvula, e uma abertura através do tampo adaptado para permitir que uma pressão de um fluido de trabalho que escoa através da válvula seja exercida na cavidade vedada acima da vedação de haste de válvula. Em uma outra modalidade ilustrativa, o dispositivo compreende um corpo, um tampo acoplado ao corpo, uma haste de válvula operacionalmente acoplada a uma passagem posicionada no corpo, uma vedação de haste de válvula posicionada entre a haste de válvula e o tampo, no qual existe uma cavidade vedada acima da vedação de haste de válvula, e uma abertura através do tampo, a abertura estando em comunicação fluida com a cavidade vedada e uma região interior do corpo. Em uma outra modalidade ilustrativa, o dispositivo compreende um corpo, um tampo acoplado ao corpo, uma haste de válvula operacionalmente acoplada a uma passagem posicionada no corpo, uma vedação de haste de válvula posicionada entre a haste de válvula e o tampo, no qual existe uma cavidade vedada acima da vedação de haste de válvula, uma câmara de pistão formada no tampo, a câmara de pistão estando em comunicação fluida com a cavidade vedada e uma região interior do corpo, e um pistão posicionado na câmara de pistão.
