Abstract

Patente de Invenção: <B>"BOMBA DE CHAVE DE PORCA DE TORQUE HIDRáULICO OPERADA A AR"<D>. Uma montagem de bomba hidráulica (10) para energizar uma chave de porca de torque hidráulico (24) é energizada a ar e tem um circuito de controle hidropneumático (39) que continua a operação de um motor a ar (18) que aciona a bomba hidráulica (16) por um período de pós-avanço depois que um atuador de avanço (55) é desativado. A operação da bomba (16) é continuada por um período suficiente para retrair uma chave de porcas de torque de dupla ação (24), para permitir avanços subseq³entes da chave de porcas (24) dentro do período de pós-avanço sem reiniciar a bomba (16) ou permitir que uma chave de porca de única ação seja movida de um prendedor para o próximo dentro do período de pós-avanço sem reiniciar a bomba (16). A operação da bomba (16) é concluída quando o período de pós-avanço expira se o atuador de avanço (55) não é reativado, de modo a conservar energia e evitar aquecimento desnecessário do fluido hidráulico.
