Abstract

1312858 I.C. engine fuel injectors ROBERT BOSCH GmbH 27 May 1971 [29 June 1970] 17373/71 Heading F1B The frusto-spherical head of a guide bush 6 in which the injector needle 5 is slidable in sealing engagement is urged against the abutment 11 by a resilient ring 19 which seals axially and radially. Metal rings 17 and 18 contacting the bore of the injector body 1 and the exterior of the bush 6 respectively are located between the ring 19 and a shoulder in the bore or on the bush.
