Abstract
The setting tool comprises a housing (1), a firing device (2) and an axially displaceable piston guide (3). The simple assembly of the piston guide (3) in the housing (1) is made possible by a centering means acting between the piston guide (3) and the housing. Guidance elements (14, 22), by means of the centering means, are eccentrically arranged on at least one of the piston guide (3) and the firing device (2) and extend essentially parallel to the setting direction. The guidance elements (14, 22) are coaxially disposable on at least one of the piston guide (3) and the firing device (2) relative to corresponding receiving openings (23) on the piston guide (3) and the firing device (2).
