1. A fastener driving tool, comprising
a tank for storing a fuel, a combustion chamber connected to the tank, wherein the combustion chamber has a movable piston for powering a driving plunger which drives a fastener, and a metering device arranged between the tank and the combustion chamber, wherein a defined quantity of fuel can be transported by means of the metering device from a metering space into the combustion chamber, and wherein the metering device comprises a thermomechanical element comprising an expansion material compound comprising a thermo-actuator that comprises a temperature-dependently positioned tappet by means of which the defined quantity can be varied as a function of a temperature. |
