Abstract (en)

[origin: EP0346275A1] The powder-actuated fastening tool possesses a piston guide (5) and a driving piston (8) displaceable therein. By means of braking balls (17) displaceably mounted in recesses (16) in the piston guide (5), the driving piston (8) is braked in the driving-in direction in that a spring (18) forces the braking balls (17) against the shaft (11) of the driving piston (8). On displacement of the driving piston (8) in the opposite direction to the driving-in direction, the braking balls (17) move in the recesses (16) out of the tension range of the spring (18), as a result of which the driving piston (8) is not subjected to any braking action. …<IMAGE>…
