In a combustion-powered fastener driving tool employing a fuel cell having an internal fuel metering valve with an axially reciprocating delivery stem, an actuator is provided for causing the dispensing of a desired dose of fuel from the fuel cell prior to each combustion event, the actuator including at least one actuator element configured for exerting an axial force on the stem, releasing the dose of fuel, and a fuel conduit associated with the element and being in fluid communication with the stem for transmitting the fuel for delivery to a combustion engine. |
