Abstract
"BOMBA DE COMBUSTìVEL DE TURBINA DE DUPLO CANAL, EM úNICO ESTáGIO". Um conjunto de bomba de fluido de turbina de estágio único (30) para uso em um sistema de envio de combustível de veículo, geralmente incluindo uma carcaça inferior (44), uma carcaça superior (42), um propulsor (48) e um motor (36). Ambas as carcaças inferior e superior têm um par de ranhuras anulares concêntricas (62A, 62B e 58A, S8B) formadas nas suas superfícies, onde as duas ranhuras anulares inferiores estão em comunicação de fluido com uma entrada de passagem de combustível (50) e as duas ranhuras superiores anulares estão em comunicação de fluido com uma saída de passagem de combustível (52). Uma rotação do propulsor faz com que uma porção do combustível entrando seja desviado para uma ranhura inferior interna e uma outra porção do combustível entrando seja desviada para uma ranhura inferior externa. Uma vez nas ranhuras inferiores, o combustível se comunica com as outras partes da câmara de bombeamento (54A, S4B), de modo que ele preencha as ranhuras superiores também. Geralmente independentes, padrões de fluxo de combustível helicoidais são formados, o que faz com que o combustível se torne pressurizado conforme ele flui da entrada para a saída. Esses padrões de fluxo de combustível helicoidais permitem uma comunicação axial entre receptáculos de palheta (6OA, 60B) e ranhuras correspondentes, mas não permitem uma comunicação radial."DOUBLE TURBINE FUEL PUMP, SINGLE STAGE". A single stage turbine fluid pump assembly (30) for use in a vehicle fuel delivery system, generally including a lower housing (44), an upper housing (42), a propellant (48) and an engine (36). Both lower and upper housings have a pair of concentric annular grooves (62A, 62B and 58A, S8B) formed on their surfaces, where the two lower annular grooves are in fluid communication with a fuel inlet (50) and the two upper annular slots are in fluid communication with a fuel passage outlet (52). One rotation of the propellant causes one portion of the incoming fuel to be diverted to an inner lower groove and another portion of the incoming fuel to be diverted to an outer lower groove. Once in the lower slots, the fuel communicates with the other parts of the pumping chamber (54A, S4B), so that it fills the upper slots as well. Generally independent, helical fuel flow patterns are formed, which causes the fuel to become pressurized as it flows from the inlet to the outlet. These helical fuel flow patterns allow axial communication between vane receptacles (60A, 60B) and corresponding slots, but do not allow radial communication.
