摘要:
A portable, internal combustion powered work device, such as a device for setting or driving fastening elements into a receiving material, includes a combustion chamber (9) wherein an air-fuel mixture is ignited. A guide cylinder (8) and a piston (7) are axially displaceably guided within the combustion chamber. When the air-fuel mixture is ignited, the piston (7) is driven and, in turn, drives a fastening element into the receiving material. Following the ignition of the air-fuel mixture and the driving of the fastening element, the combustion chamber volume is reduced to approximately zero, whereby a purely mechanical clearing of the combustion chamber is effected without the necessity of an additional flushing air flow.

A hand-held drive-in tool for driving fastening elements (60) in a workpiece (U) includes a drive-in ram (13) displaceable in a guide (12), a spring (31) for driving the drive-in ram (13), a tensioning device (70) for loading the driving spring (31), a locking device (50) for retaining, in its locking position (54), the driving spring (31) in its loaded position thereof (33), and a sliding nut (78) supported on a threaded spindle (76), which is rotatable by the motor (71) of the tensioning device (70), without a possibility of rotation thereabout but with a possibility of an axial displacement therealong, the sliding nut (78) being axially displaceable, upon actuation of the motor (71) of the tensioning device (70) by a control unit (23) of the drive-in tool (10), from the first end position (83) to the second end position (84) for displacing the driving spring (31) into the loading position (33) of the driving spring (33), and being subsequently displaceable from its second end position (84) into the first end position (83) to provide for displacement of the driving spring (31) to its release position.
摘要:
The present invention relates to a pressurized package and a method for manufacturing and filling a pressurized package. The pressurized package has an outer container (10) and an inner container (20) situated within the outer container (10). In the outer container (10) a chamber (11) for material (12) to be dispensed is arranged and in the inner container (20) a propellant chamber (21) for propellant (20) is arranged, which are separated from each other in a manner that is impermeable to liquid and gas. The outer container (10) is closed by a cover part (15) on which a valve part (16) is arranged for dispensing the material (12) from the chamber (11) outwards. To improve pressurized packages of this type, a pressurized cartridge (30) containing a propellant (22) is arranged in the inner container (20), and the pressurized cartridge is associated with an opening mechanism (31) for at least one-time opening of the pressurized cartridge (30) to the propellant chamber (21) of the inner container (20). The opening mechanism (31) reacts to filling of the chamber (11) with material (12) to be dispensed.

A drive-in tool (10) for driving in fastening elements (60) includes a driving ram (13) which is displaceably supported in a guide (12), a drive unit (30) for the driving ram (13) and having at least one drive flywheel (32) which is set in rotation by an electric motor (31), and a return element (70) for displacing the driving ram (13) its initial position (22) after the completion of the drive-in process and formed as an over-pressure gas spring (70).
摘要:
The present invention relates to an internal combustion-operated setting tool for driving fastener elements such as nails, bolts, pins into a substrate, having a fuel source, with a fuel feed line from a fuel source to a combustion chamber and having at least one dosing device (30), which is arranged between the fuel source and the combustion chamber. For improving such setting tools, a displacement body (50) is arranged in a chamber in the dosing device (30) for forcing fuel out of the chamber, whose displacement volume can be adjusted.

A combustion-engined setting tool for driving fastening elements in a constructional components includes at least one mechanically controlled valve (14) arranged in a feeding conduit (12) that connects a reservoir (11) with an oxidation agent or fuel with the tool combustion chamber (13), a switch element (15) for time-delayed opening of the mechanically controlled valve (14) upon being actuated, and at least one normally open, electronically controlled valve (24) likewise arranged in the feeding conduit.
摘要:
A tool for driving fastening elements (40) into a receiving material (U) includes a housing (1) with a throughbore (3), a channel (5) extending transversely and opening into the throughbore, and a guide (8). A driving device (2) is axially displaceable through the guide (8). The driving device (2) has an axially extending guide tube (9) in which a ram (7) is axially displaceable. Axial displacement of the driving device (2) is converted by control elements (10a, 10b) into transverse movement of a slide (6) located within the channel (5). The slide (6) cooperates with a separation device (12) in the form of a spring-loaded pawl at a magazine (11) holding the fastening elements (40). The magazine is mounted on the housing by a quick disconnect fitting.
