Abstract

BOMBA DE COMBUSTÍVEL DE ALTA PRESSÃO. A presente invenção refere-se a uma bomba de combustível de alta pressão (10) para um sistema de combustível para um motor de combustão interna, em que a bomba de combustível de alta pressão (10) tem uma carcaça de bomba (12) que apresenta um corpo de bomba (12a) e uma tampa de bomba (12b) montada no corpo da bomba (41), em que a bomba de combustível de alta pressão (10) apresenta um compartimento de bombeamento (16) que está disposto no corpo da bomba (12a) e é delimitado por um pistão de bomba deslocável (18), em que a bomba de combustível de alta pressão (10) apresenta uma válvula de entrada (14) que se abre de uma área de baixa pressão (71) da bomba de combustível (10) para o compartimento de bombeamento (16), em que a bomba de combustível de alta pressão (10) possui uma válvula de saída (20), que abre para fora do compartimento de bombeamento (16) na direção de uma saída (34) da bomba de combustível de alta pressã(10), em que o compartimento de amortecedor (72), que pertence à área de baixa pressão (71), na qual está disposta uma caixa de amortecedor (30a) formada por duas membranas metálicas (73) soldadas uma à outra em suas bordas, é formado entre o corpo da bomba (12a) e a tampa da bomba (42), em que duas molas de anel de retenção (30b, 30c) de construção idêntica fixam um lado da caixa de amortecedor (30a) contra a tampa da bomba (12b) e o outro lado da mesma contra o corpo da bomba (12a).HIGH PRESSURE FUEL PUMP. The present invention relates to a high pressure fuel pump (10) for a fuel system for an internal combustion engine, wherein the high pressure fuel pump (10) has a pump housing (12) which has a pump body (12a) and a pump cover (12b) mounted on the pump body (41), the high-pressure fuel pump (10) having a pumping compartment (16) which is arranged in the body of the pump (12a) and is delimited by a displaceable pump piston (18), the high pressure fuel pump (10) having an inlet valve (14) which opens from a low pressure area (71) from the fuel pump (10) to the pumping compartment (16), where the high pressure fuel pump (10) has an outlet valve (20), which opens out of the pumping compartment (16) in the direction from an outlet (34) of the high-pressure fuel pump (10), in which the damper compartment (72), which belongs to the low-pressure area (71), in which a damper housing (30a) formed by two metallic membranes (73) welded together at their edges, is formed between the pump body (12a) and the pump cover (42), in which two retaining ring springs (30b, 30c) of identical construction fix one side of the damper box (30a) against the pump cover (12b) and the other side against the pump body (12a).
