Definitions

a powder-operated bolt setting device is known, the one Has guide housing for driving piston guide. Between the guide housing and a relatively displaceable handle part, a spring is provided which recoil acting on the operating personnel during the driving-in process of the bolt should absorb and dampen.
the damping effect of such a spring solution is only sufficient for small spring rates.
a small spring rate requires a large one Spring and increased space requirements, which means with such a damping device equipped device becomes unwieldy.
the use of a smaller spring with a larger one Spring rate in turn reduces the damping effect, so that the operating personnel still a high proportion of the undesirable recoil forces.
the Return speed in such known Fedem very high, so that also Reset undesirable vibrations affecting the operating personnel occur.
a powder-operated setting tool which the features listed in claim 1.
a generic powder-operated setting tool is used improved that the hydropneumatic damping device is free of moving Valve parts is, and that for that during the displacement process of the piston displaced liquid medium at least one passage opening is provided, which has a minimum cross section and is designed such that the liquid medium, which occurs when the piston is immersed in the setting direction in the front Cylinder space flows, has an effective flow cross-section that the Minimum cross section corresponds to the passage opening, while when the Pistons the effective flow cross section of the counter to the setting direction in the rear Cylinder space flowing liquid medium smaller in the area of the passage opening is their minimum cross section.
the effective one Flow cross section S from the rear 26 into the front cylinder space 25 overflowing liquid medium 21 corresponds to the minimum cross section of the Through openings 24.
This minimum cross section and the number of Through openings 24 are selected such that rapid, damped immersion of the piston 23 takes place.
FIG. 3 and 4 is the mode of operation of the damping device 17 according to the invention schematically shown with specially designed passage openings 24.
the Detail of the damping device 17 in Fig. 3 is the Immersion process of the piston 23 indicated by the arrow E.
the immersion process flows the liquid medium 21 out of the rear cylinder space 26 through the passage opening 24 into the front cylinder space 25.
the passage opening 24 is from the cylinder wall 18a and the piston surface 23b facing it limited.
the liquid medium 21 is indicated by flow lines.
the special design of the passage opening 24 it remains essentially one laminar flow and the effective flow cross-section of the liquid medium corresponds to the minimum cross section M of the passage opening 24.
Fig. 5 shows a similar embodiment of another embodiment of the Damping device 17.
the passage opening 24 is in the bypass Wall of the cylinder 18 provided.
the bypass has two mouths that pass through a channel 24c are connected.
a front mouth 24a is in the front Cylinder chamber 25 arranged in front of the rest position of the piston 23 and a rear one Mouth 24b is located in the rear cylinder space 26 behind the maximum Immersion position of the piston 23.
the displacement of the piston 23 extends between the two mouths 24a and 24b.
the different behavior of the Damping device 17 when immersing the piston 23 or when resetting is by the different formation of the mouths achieved.
the rear mouth 24b is preferably funnel-shaped and largely free of sharp edges Boundaries.
the front mouth 24a has sharp edges where vortices occur that continue through channel 24 c and become one Lead jet contraction of the flowing medium.
