1. A gas-powered fastener-driving tool comprising:
a combustion or precombustion chamber;
a valve comprising a body that is mobile within the combustion or precombustion chamber between a first closed position and a second open position, wherein the body defines two opposing orifices at longitudinal ends of the body, wherein the orifices form part of a bore defined through the body that enables gas to pass longitudinally through both orifices of the body of the valve into the combustion or precombustion chamber;
a spring configured to bias the body to the second open position; and
a trigger mounted to a handgrip, wherein the trigger is actuatable to cause the body to move from the second open position to the first closed position.
