Abstract

"BOMBA DE ENGRENAGEM, EM PARTICULAR, PARA UMA BOMBA DE COMBUSTìVEL DE ALTA PRESSãO". No caso de uma bomba de engrenagem com uma carcaça (18), duas rodas dentadas (14, 16) que estão dispostas na carcaça, e estão engrenadas entre si, e com pelo menos, uma ranhura (22) que é construída na carcaça no lado de pressão da bomba de engrenagem, devem ser evitados danos de cavitação em altos números de rotação. Para essa finalidade está previsto que, a ranhura apresente uma primeira seção (24), que se estende partindo do lado de pressão, e na qual o fundo da ranhura (22) tem um intervalo pequeno das pontas dos dentes (20) da roda dentada, e uma segunda seção (26), que se liga à primeira seção, e na qual o fundo da ranhura (22) apresentam um intervalo máximo das pontas do dente, que é maior do que o intervalo na primeira seção, sendo que a primeira seção se estende através de uma área de ângulo (<244>) menor do que a segunda seção, e a ranhura se estende. ao todo, através de uma área de ângulo (<244>, <225>) que é um pouco maior do que o intervalo de ângulo entre dois dentes (20).
