High pressure fuel injector extraction tool for motor vehicle e.g. car, field, has extraction device with inertia rod placed over protection cap of injector head, and gripper with branches forming tab supported on flange formed around head

摘要

#CMT# #/CMT# The tool has an extraction device comprising a rectilinear and rigid inertia rod (4) that is placed over a protection cap (3) of an injector head. The rod is engaged and screwed in a gripper core (7), and is retained using a nut (8) which is screwed around the rod to butt on an upper radial side of a tubular body constituting the core. A gripper has branches (10) each presenting a radial extension extending inwards to form a latching tab (14) that is supported on a flange (15) formed around the head. #CMT# : #/CMT# An independent claim is also included for a method for extracting fuel injector from a spark ignition engine. #CMT#USE : #/CMT# Used in the motor vehicle e.g. car, field for extracting high pressure fuel injector from a spark ignition engine (claimed) e.g. high pressure Diesel type internal combustion engine. #CMT#ADVANTAGE : #/CMT# The tool permits the fuel injector to be extracted from the spark ignition engine without the risk of damaging the extraction device during movement, and without damaging the injector head. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial cross sectional view of a non destructive extraction device. 3 : Protection cap 4 : Inertia rod 7 : Gripper core 8 : Nut 10 : Branches 14 : Latching tab 15 : Flange.
