The invention relates to a device for transmitting energy to a fastener, with a reaction chamber, an energy-transmission element that can move in a fastening direction for transmitting energy released in the reaction chamber to a fastener, a first supply channel opening into the reaction chamber for feeding a first reagent to the reaction chamber, wherein the first supply channel comprises a feeder device for feeding the first reagent into the reaction chamber and a controllable closing device for a time-wise closing of the first supply channel.

Device for transmitting energy to a fastener

The invention relates to a device for transmitting energy to a fastener, with a reaction chamber, an energy-transmission element that can move in a fastening direction for transmitting energy released in the reaction chamber to a fastener, a first supply channel opening into the reaction chamber for feeding a first reagent to the reaction chamber, wherein the first supply channel comprises a feeder device with a rotor and a feeder element for feeding the first reagent into the reaction chamber.

A setting tool for driving a fastening element in a constructional component includes a housing (), a drive member () displaceable in a guide () located in the housing, a bolt guide () adjoining the drive member guide () in direction of the operational axis (A) and forming a dog point () for abutting the constructional component and a drive-in depth setting tool () for displacing the bolt guide () axially relative to the drive member guide () for setting a distance between a drive end () of the drive member () and the dog point () in the initial position of the drive member.

Setting tool

A switching adapter for enabling individual settings with a hand-held setting tool () having a magazine () for fastening elements (), and a detection element () for detecting presence of a fastening element () in a receiving chamber of the setting tool. The adapter () includes a retaining section () for releasably mounting the switching adapter () on the fastening elements magazine () of the setting tool (), and an actuation section () that displaces the detection element () of the setting tool from its a locking position to its release position.

Switching adapter for individual settings with hand-held setting tool

A combustion-engined setting tool () for driving fastening elements in a workpiece includes a combustion chamber (), a drive piston () displaceable in a piston guide () and driven by expanding gases produced in the combustion chamber (), and a device for returning the drive piston () in its initial position as a result of pressure difference between chambers formed on opposite axial sides of the piston head (), and including a pump ().

Combustion-engined setting tool

A hand-held drive-in tool for driving fastening elements, includes a driving ram () displaceably arranged in a guide (), a drive unit () for displacing the driving ram (), a press-on element () for controlling the safety element () of the drive unit () and spring-biased in a drive-in direction, and a device for changing a biasing force applied to the press-on element () dependent on a special orientation of the press-on element () relative to a vector (G) of a gravitational force.

Hand-held drive-in tool

A combustion-engined setting tool for driving fastening elements in a constructional component end including a combustion chamber () for combusting a gas mixture, an inlet/outlet device () for opening the combustion chamber () in its first position and for closing the combustion chamber () in its second position and having a valve element for reversibly displacing the inlet/outlet device () between its first and second positions, a locking element () for locking the valve element of the inlet/outlet device () in the second position of the device, a trigger () for actuating the locking element (), a release switch () for triggering ignition in the combustion chamber (), an electronic control unit () for controlling start of the ignition in the combustion chamber (), and an initialization switch connected with the control unit (), the control unit () initiating the ignition in the combustion chamber () when a time period between switching-on of the initialization switch and switching-on of the release switch (), which is also connected with the control unit, does not exceed a predetermined set time period.

A combustion-engined setting tool for driving fastening elements in a constructional component includes a guide cylinder (), adjoining the combustion chamber () and in which a setting piston () is displaceable, a press-on element (), and a transmission device for connecting the press-on element () with the combustion chamber rear wall () for axially displacing same in response to a press-on stroke of the press-on element, with the transmission device being formed as a cable drive () having a transmission member () and at least one deflection roller () for the transmission member ().
