a minimum lift and the diameter of the holes 62 in the tube should be smaller than this minimum lift the material composition and wall thickness of the tube 58 should be such that the tube compresses during installation without excessive strain that would affect the diameter of the holes 62 fig3 shows a second embodiment in which the debris diverter shield 32 is in a different location within the injector and the associated passages for achieving control of the injector differ from those shown in fig2 in fig3 components which are identical to those shown in fig2 carry the same numeric identifier whereas components that are not identical but provide the same or similar functionality are indicated with a prime u2032 in this embodiment the debris shield 32 is located in the upper portion 30 a u2032 of the high pressure passage within the upper block 70 u2032 and the lower portion 30 b in block 72 and intermediate portion 30 c u2032 in block 74 u2032 are straight bores the lower portion of passage 30 a u2032 has a counter bore 82 defining an internal shoulder 84 the upper end 66 of the diverter shield 32 bears against the shoulder 84 and the lower end 68 of the diverter shield 32 bears against the upper surface 76 u2032 of the intermediate block 74 u2032 as with the embodiment of fig1 and 2 the diverter shield 32 is thereby compressed and rigidly held in position high pressure fuel in passage 30 a u2032 enters the debris diverter 32 with some flow passing.
