Abstract

"BOMBA DE ALTA PRESSãO COM FLUXO VARIáVEL". (1) que compreende pelo menos um pistão (4) montado de forma a deslizar axialmente e de maneira hermética no interior de uma cavidade cilíndrica (5) obtida no corpo (6) da bomba, de forma a definir uma câmara de bombeamento de volume variável (7) adaptada para enchimento com um fluido, e uma válvula de entrada (9) e uma válvula de fornecimento (8) adaptada para permitir o fluxo de uma via do fluido, respectivamente, para dentro e para fora da câmara de bombeamento (7), com a válvula de entrada (9) sendo formada por uma válvula sem retorno (9) que compreende um corpo obturador (10) que pode mover-se de e para uma posição fechada, na qual ele evita a passagem do fluido através da válvula, e um membro elástico (12) adaptado para manter o corpo obturador (10) na posição fechada mencionada acima e a bomba de alta pressão (1) compreendendo adicionalmente um pistão hidráulico (14) adaptado seletivamente para distanciar o corpo obturador (10) da posição fechada, superando a resistência do membro elástico (12), de forma a permitir que o fluido também flua livremente através da válvula em direção oposta à direção normal.
