A setting tool includes a sleeve-shaped housing (), a piston guide () and an ignition unit () located in the housing (), with the ignition unit () having a cartridge chamber bottom () for enclosing a propellant () in cartridge chamber (), which is located between the piston guide () and the ignition unit () and a locking device () having a locking position () in which the ignition unit () is held in a pre-loaded position () against an energy accumulator () and in which the cartridge chamber () remains open, and having a release position () in which the ignition unit () is displaced to its ignition position () by the energy accumulator in which the cartridge chamber bottom () closes the cartridge chamber ().

Setting tool

An explosive powder charge-operated setting tool, including a guide cylinder (,), a drive piston (,) displaceably supported in the guide cylinder bore (,), a carrier (,) having in its end region facing in a direction opposite to the setting direction, a catridge-receiving chamber (,) and a first active surface (,) facing in the setting direction and from which a cylindrical projection (,) extends with an end surface of the cylindrical projection (,) facing in the setting direction forming a second active surface (,), with the first active surface (,) of the carrier (,) cooperating with a stop surface (,) provided on the drive piston, with the drive piston (,) having a cylindrical recess (,) extending from the stop surface (,) for receiving the projection, and with the tool further including a connection channel connecting the second and first active surfaces.

Explosive powder charge-operated setting tool

The powder force-driven setting tool including a piston guide (1) having cartridge-receiving seat (3), a discharge channel (4) and a bore (2) in which a drive piston (5) is displaceable parallel to the setting direction, the cartridge-receiving seat (3) and discharge channel (4) opening into the bore (2), a sealing region (6) is formed by the drive piston (5) and the piston guide (1). between the mouth of the cartridge-receiving seat (3) and the discharge channel (4).

Powder force-operated setting tool

A setting tool for driving nail-shaped attachment elements into a hard structural component, including a housing (1), a guide cylinder (8) located in the housing (1), a drive piston (7) axially displaceable in the guide cylinder (8) and having a driving surface (74), a spring-biased lever-shaped resetting member (1) pivotable in a plane extending parallel to a setting direction and engageable with the driving surface (74), and a device for displacing the resetting member (1) out of a plane of axial projection of the driving surface (74) into a release position of the resetting member.
