Abstract

"CONJUNTO DE BOMBA EM SéRIE COM SISTEMA DE ANULAçãO DE CONTROLE DE BOMBA". Um conjunto de bomba em série do tipo incluindo um alojamento (H) definindo um orifício de entrada de fluido (37) e um orifício de saída de fluido (35), uma primeira bomba (11) disposta no alojamento (H) e acionada por um eixo de entrada (19) . A primeira bomba (11) compreende uma bomba linear, de deslocamento variável, incluindo primeiro meio responsivo à pressão (31) para variar o deslocamento da primeira bomba (11) em resposta à entrada de uma pressão de controle (47). A primeira bomba tem uma entrada (67) em comunicação fluida com o orifício de entrada de fluido (37), e uma saída (65) em comunicação fluida com o orifício de saída de fluido (35). Uma segunda bomba (33) é disposta no alojamento (H) e acionada pelo eixo de entrada (19), a citada segunda bomba tendo uma entrada em comunicação fluida com o orifício de entrada de fluido (37), e uma saída em comunicação fluida com o orifício de saída de fluido (35) . o conjunto é caracterizado pelo conjunto de bomba em série incluir meio de válvula de anulação de pressão (71, 73) associado com somente a primeira bomba (11), e operável, em resposta a uma pressão de fluido no orifício de saída de fluido (35) excedendo um ajuste de anulação de pressão (79), para comunicar fluido pressurizado para o primeiro meio responsivo à pressão de fluido (31), de uma maneira tendendo a diminuir o deslocamento da primeira bomba (11) sem afetar o deslocamento da segunda bomba (33), até que a citada pressão de fluido seja substancialmente igual ao ajuste de anulação de pressão (79), mesmo se for necessário para a primeira bomba (11) estar sobre a centro a partir de seu deslocamento inicial.
