摘要:
A propellant magazine for a propellant-operated setting tool and including a pocket foil (1, 11, 21) having a plurality of recessed, spaced from each other, pockets (2, 12, 22, 42) for receiving each a propellant (3, 13, 23), a cover foil (5, 15, 25) unreleasably connected with the pocket foil (1, 11, 21) for closing the pockets (2, 12, 22), and an electrically conducting strip (7, 17, 27, 37) associated with each pocket (2, 12, 22, 42) and having at least one contact point (8, 9, 18, 19, 28, 29, 31, 32, 38, 39).
摘要:
A combustion-operated setting tool for driving fastening elements in a constructional component includes a device (30) for adjusting setting energy applied to a setting piston (15) axially displaceable in a guide space (4) of a piston guide (13). The adjusting device (30) has a separation member (31) adjustably arranged between the receptacle (18) and the guide space (14) of the piston guide (13) and dividing the combustion chamber (20) in a first sub-chamber (21) arranged between the receptacle (18) and the separation member (31) and a second sub-chamber (22) arranged between the separation member (31) and the guide space (14) of the piston guide (13), the separation member (31) having a plurality of through-openings (34, 35) for controlling flow of the combustion gases into the guide space (14) of the piston guide (13), with an active opening cross-section of at least a portion of the through-openings (34, 35) changing dependent on an adjustable position of the separation member (31).
摘要:
A combustion-operated working tool having a housing body (1), which has a cylindrical recess (5) and a piston chamber (2) connecting therewith for receiving a piston (3); an impact plate (8), which is arranged opposite to and at a distance to the cylindrical recess (5) and which can be displaced towards and away from the housing body (1), and a packing sleeve (12) arranged inside and elastically mounted, projecting out of the cylindrical recess (5).
摘要:
A combustion-operated setting tool (10) for driving in fastening elements, includes a combustion chamber (15), a ventilator (16), and a motor (17) for driving the ventilator (16). The motor (17) is mounted in a receptacle (20) of a motor-supporting member (21) and is supported at least at one of its axial ends (24, 25) by an annular damping element (30) at a wall portion (22, 23) defining the receptacle (20), with an annular recess (33) arranged at the circumference of the annular damping element (30).
