ABSTRACT:
An automatic injector insertion station for inserting a fuel injector mounting end into a fuel rail cup includes a housing and an injector nest moveable relative to the housing. The nest includes first and second ends. The first end includes a support for supporting and guiding the injector, and is moveable between a preload position, wherein the fuel injector mounting end is adjacent the fuel rail cup, and an insertion position, wherein the mounting end and o-ring are mounted in the fuel rail cup. A compression spring is mounted in the housing and connected with the second end of the injector nest. A piston and cylinder arrangement is operable for compressing the compression spring to a loaded compressed position. The injector nest is moveable by the compression spring compressive force from the preload position to the insertion position to assemble the fuel injector and o-ring into said fuel rail cup through linear spring force, thus preventing damage to the o-ring.
