Abstract
A handheld combustion powered fastening tool may include a driving system that drives fasteners into workpieces in response to combustion of fuel by the driving system. A fuel delivery system may supply fuel to the driving system. The fuel delivery system may include a fuel canister storing liquid fuel, such as liquid hydrocarbons such as propane, and all direction valve, supplying fuel from the fuel canister to the driving system for combustion. The valve may supply fuel to the driving system in a multiplicity of orientations of the valve/canister/tool, allowing the tool to be operable in a plurality of different orientations, including an upright orientation and an inverted orientation.
