Patent ID: 7048167

Claim:
A combustion-driven setting tool for fastening elements, having a unit housing ( 1 ); a piston guiding cylinder ( 22 ), which is mounted in the unit housing ( 1 ) for displacement in a longitudinal direction of the guiding cylinder; a piston ( 21 ) guided in a piston guiding cylinder ( 22 ) for driving in a fastening element ( 13 ) into a receiving material ( 18 ); a receiving assembly ( 12 ) situated coaxially to the piston guiding cylinder ( 22 ) for the fastening element ( 13 ), which, viewed in a driving direction ( 19 ), lies in front of the piston guiding cylinder ( 22 ) and can be displaced relative thereto; an elastic adjustment assembly ( 30 ), which constantly tends to separate the receiving assembly ( 12 ) and the piston guiding cylinder ( 22 ) from each other; and a piston mounting ( 31 ), which is secured to an end of the receiving assembly ( 12 ) facing towards the piston guiding cylinder ( 22 ), wherein the receiving assembly ( 12 ) passes into a guide assembly ( 9 ) at its end facing away from the driving direction ( 19 ), which on the one hand is displaceably held in the unit housing ( 1 ) in the longitudinal direction of the piston guiding cylinder ( 22 ), and on the other hand displacingly receives the piston guiding cylinder ( 22 ).
