Definitions

  • the application relates to a device for driving a fastener into an underground.
  • Devices of this type usually have a piston for transmitting energy to the fastening element.
  • the energy required for this has to be made available in a very short time, which is why, for example in so-called spring nailers, a spring is first tensioned, which suddenly releases the clamping energy to the piston during the driving process and accelerates it to the fastening element.
