Abstract

"BOMBA DE COMBUSTìVEL TIPO MOTOR PARA VEìCULO". Em uma área limítrofe entre uma parte de alta pressão na qual uma porta de descarga (8) de uma bomba de combustível é disposta e uma parte de baixa pressão na qual uma porta de entrada (7) é disposta, um sulco de alívio de pressão (33) se estendendo ao longo da área limítrofe é formado de forma a ser comunicado com o exterior da bomba por meio de um furo de alívio de pressão (34). Alternativamente, um corte (36) é formado comunicado com o exterior. De acordo, um combustível em uma parte de área de alta pressão pode ser drenado com confiabilidade. Adicionalmente, pela comunicação do sulco de alívio de pressão acima (33) com uma porta de inserção de pino de posicionamento (11), um único furo pode servir ambos um furo de inserção de pino de posicionamento e um furo de alívio de pressão.
