Abstract

"INJETOR". A invenção refere-se a um injetor (2) para um sistema de injeção Common-Rail de um motor de combustão interna, com uma caixa de injetor (4), uma peça de válvula (8) disposta na caixa de injetor (4), um anel de vedação (22) servindo de vedação entre uma zona de alta pressão e uma zona de baixa pressão do injetor (2), bem como um anel de apoio juntamente com o anel de vedação (22) disposto em um compartimento anelar (18) entre a caixa de injetor (4) e a peça de válvula (8), servindo para o apoio do anel de vedação (22), anel de apoio (24) este que, em seu lado inferior de costas para o anel de vedação (22), é munido de várias ranhuras de descarga (36) dispostas à distância na direção periférica, e em sua borda periférica externa (28) é munido de vários rebaixos (34) dispostos à distância na direção periférica. é previsto que as ranhuras de descarga (36) e os rebaixos (34) estejam dispostos deslocados na direção periférica.
