ABSTRACT:
A fuel injector, which is principally for use in a compression ignition engine, comprises a body having a bore therethrough in which a valve member is slidably mounted for co-operation with a seating to contro1 the flow of fuel past the latter, the valve member being biased into engagement with the seating by a compression spring. The biasing force of the spring, and therefore the fuel pressure at which the valve member opens, can be adjusted by rotating a collar relative to the body. The collar is both internally and externally screw-threaded, and engages complementary threading on the interior of the bore. An externally screw-threaded retaining member engages the internal threading on the collar and also has an abutment which engages the body, the retaining member serving to retain the collar in position in the bore. Once the biasing force of the spring has been set by rotating the collar, the retaining member prevents the collar from being inadvertently rotated subsequently.
