摘要： The invention relates to an extractor (1), a process and a set of tools for extracting a safety screw or a broken screw, consisting of inserting an extractor (1) into a hollowed bore (17) in said screw, by inserting the rod (3) of the extractor (1) into said bore (17) and by percussion on the head (7) of said extractor (1) using a percussion tool (49), so as to couple the extractor (1) and the screw (13) in rotation; and extraction of the screw (13) by loosening it using a key suitable for with the head (7) of the extractor.

摘要： The invention involves the extraction process of a glow plug pencil (23) or a broken pencil (23) which is stuck in a cylinder head (13) housing (11) of a glow plug engine comprising a lower (19) and upper (17) part, so that the upper part (17) forms a shoulder (21) with the lower part (19), the pencil (23) being stuck in the lower part (19). The process is remarkable in that it includes a step (a) for drilling a bore in the pencil (23) according to the longitudinal direction of the latter which is performed with the use of a drill bit (1) comprising a drilling part (5) with flutes (7) and a shank (3) respectively having a diameter smaller and greater than the lower part diameter (19) of the housing (11) so that the shank (3) forms a shoulder (9) with the drilling part (5), and in that step a) for drilling the bore includes the drilling of the pencil (23) until the said shoulder (9) of the drill bit (1) is positioned to a stop against the shoulder (21) of the housing (11).

摘要： Extraction process of an injector (1) stuck in its housing (3) within a cylinder head (5) of a motor vehicle, the said injector (1) comprising a body (9), a part of which protrudes from the outside of the housing (3), the protruding part having a high-pressure connection (13), the process comprising the mounting of an extractor (15) to the high-pressure connection (13) of the injector (1); and the extraction of the injector (1) by using the extractor (15). The process is remarkable in that step b) dealing with the extraction of the injector (1) includes the retrieval of the injector (1) so as to trigger the rotation of the injector (1) around the longitudinal axis of the injector 1.

摘要： The invention involves the extraction process of a glow plug pencil (23) or a broken pencil (23) which is stuck in a cylinder head (13) housing (11) of a glow plug engine comprising a lower (19) and upper (17) part, so that the upper part (17) forms a shoulder (21) with the lower part (19), the pencil (23) being stuck in the lower part (19). The process is remarkable in that it includes a step (a) for drilling a bore in the pencil (23) according to the longitudinal direction of the latter which is performed with the use of a drill bit (1) comprising a drilling part (5) with flutes (7) and a shank (3) respectively having a diameter smaller and greater than the lower part diameter (19) of the housing (11) so that the shank (3) forms a shoulder (9) with the drilling part (5), and in that step a) for drilling the bore includes the drilling of the pencil (23) until the said shoulder (9) of the drill bit (1) is positioned to a stop against the shoulder (21) of the housing (11).
