ABSTRACT:
A fuel injector having a needle valve and an injector body employs at least one movable needle-guide which having a plurality of movable members disposed between the needle valve assembly and the injector body. The movable members can be insulating members which are substantially entirely composed of insulating material such as ceramics. In applications which do not require electrical isolation, the movable members could be formed of conductive material. The movable members are preferably spherical elements which are partially cradled within an annular trough formed in the needle valve such that the movable members ensure that the needle valve is held in spaced relation to the injector body. While the movable members are preferably formed as solid ceramic spheres, other insulating materials and/or shapes could be utilized.
