Abstract

sistema de regulação da pressão de fluidos de barreira de motor e bomba, controlado por pressão diferencial. a presente invenção divulga um sistema de regulação da pressão de fluidos de barreira de motor e bomba, utilizados em um módulo submarino de motor e bomba. o sistema de regulação da pressão compreende: - um circuito de fluido de barreira (10), que proporcionasuprimento de fluido hidráulico (8) para uma primeiracavidade no módulo de motor e bomba; - uma válvula de controle de fluxo de pressão controlada (9), que controla o suprimento de fluido hidráulico ao circuito de fluido de barreira (10); - uma segunda cavidade, disposta para recebimento de fluido hidráulico proveniente do suprimento de fluido hidráulico através da primeira cavidade; e - um circuito piloto de pressão (11), compreendendo meios para detectar e retornar para a válvula de controle de fluxo de pressão controlada (9) uma pressão diferencial, através de uma restrição de fluxo (7; 13), que conecta as primeiras e segunda cavidades.
