摘要:
A combustion-engined setting tool for driving fasting elements such as nails, bolts, pins in an object, includes a combustion chamber (13), a fuel source (11), a fuel conduit (12) connecting the fuel source (11) with combustion chamber (13) for feeding fuel thereinto, and at least one metering device (30) for metering a predetermined amount of fuel for effecting a setting process and having at least one variable volume metering chamber (31), and a displaceable piston body (34) for a pulsed ejection of fuel from the metering chamber (31).
摘要:
The present invention relates to a propellant container (2) for an internal combustion operated setting tool (10) having a housing (21) and a housing internal space (22) for receiving a propellant (23). A portable electrical power source (40) such as a battery or a battery pack is arranged on the propellant container (2). The invention further relates to an internal combustion operated setting tool (10) having electrical consumers (30), a setting mechanism (12) that can be driven by a propellant (23) and a receptacle (15) for a propellant container (20). Contact elements (31, 32) for contacting an electrical power source arranged on the propellant container (20) are arranged on the receptacle for the propellant container (20).
摘要:
A portable, internal combustion-engined tool includes a combustion chamber (1), a piston (8) adjoining the combustion chamber (1), with a pressure build-up in the combustion chamber (1) providing for movement of the piston (8) from its initial position, in which the piston adjoins the combustion chamber (1), away from the combustion chamber (1). A brake device (43) retains the piston (8) substantially in its initial position during build-up of pressure in the combustion chamber (1), with a braking force applied to piston (8) being changeable for adjusting the amount of energy generated in the combustion chamber and transmittable to the piston (8).
