601546 Disclosed is a fuel cell assembly for a fastener driving tool to allow for the use of different fuel cell canisters with the tool. The fuel cell assembly for a fastener-driving tool, comprises one of an in-can fuel cell and an on-can fuel cell, each of the fuel cells having a valve closure formation. An adapter includes a ring portion configured for engagement upon the fuel cell closure formation and includes a top edge defining at least one indentation, a bottom edge defining at least one gap in vertical alignment with the indentation, and a sidewall therebetween having an inner sidewall and an outer sidewall, the inner sidewall defining at least one track extending from the top edge to the bottom edge, and the outer sidewall having a convex gripping formation complementary to the closure formation. A cap is constructed and arranged for being removably secured to the adapter and including at least one leg portion each having a foot constructed and arranged for being received in the track and a detent radially extending from the foot and configured for being received in the gap upon rotation of the cap relative to the adapter. The cap is one of an in-can cap and an on-can fuel metering valve. The at least one track is a pair of tracks, each track beginning at opposite sides of the top edge and extending in opposite directions to the bottom edge in a helical formation, the gap defining an end of the track. |
