Abstract

a presente invenção se refere a uma bomba de combustível de alta pressão (12) compreendendo um canal de entrada (14) em ligação com uma primeira câmara (16), através da qual o canal de entrada é conduzido para a primeira câmara (16), uma segunda câmara (18) disposta em ligação com a primeira câmara (16), uma válvula de saída (40) disposta em ligação com a segunda câmara (18) e uma válvula de entrada (20) compreendendo um pistão (22), com uma primeira extremidade de seção (24) e uma segunda extremidade de seção (26). o pistão (22) é disposto de forma móvel com relação à primeira extremidade de seção (24) em uma terceira câmara (28), e a segunda extremidade de seção (26) é disposta de forma móvel entre a primeira câmara (16) e a segunda câmara (18). o elemento de compressão (34) é disposto para atuar sobre o pistão (22) com uma força mecânica (fs), de tal modo que o pistão (22) seja forçado a se posicionar, com relação à segunda extremidade de seção (26), de forma a fechar a ligação entre a primeira câmara (16) e a segunda câmara (18). como um resultado, a válvula de entrada (20) está em um estado fechado. a válvula de entrada (20) pode ser controlada através de uma unidade eletromagnética (38).
