Abstract

Válvula de desligamento para controle da velocidade de fluxo de bomba de combustível para motor a combustão Interna. Válvula de desligamento (21) da velocidade de fluxo de bomba de combustível (6) para motor a combustão interna; em que a válvula de desligamento (21) é equipada com: corpo cilíndrico tubular (25), que é fechado no topo, exibe assento cilíndrico (26), cuja parte inferior desempenha a função de cano de combustível e compreende uma série de orifícios radiais (27) para permitir a introdução de combustível no assento cilíndrico (26); placa inferior (28), que é disposta no corpo cilíndrico tubular (25) e abaixo dos orifícios radiais (27) e possui orifício centra| que define abertura de saída (24) do combustível e impulsionador cilíndrico (29), que é acoplado à placa inferior (28) e é móvel entre posição aberta, na qual a abertura de saída (24) encontra-se em comunicação com os orifícios radiais (27), e posição fechada, na qual a abertura de saída (24) é isolada dos orifícios radiais (27).
