Metering valve for a fuel cell

Valve cap for a fuel cell

A combustion nailer is configured for use with a fuel cell having an internal metering valve and a reciprocating, biased main stem. The nailer includes a tool housing defining a fuel cell chamber constructed and arranged for receiving the fuel cell, a fuel cell actuator assembly configured for actuating the fuel cell in the chamber to emit a measured dose of fuel during tool operation, and a fuel delivery apparatus associated with the actuator assembly for receiving the emitted dose of fuel and providing it to a combustion chamber. The fuel delivery apparatus is configured for preventing actuation of the main stem by the actuator assembly upon the fuel cell being adapter-free.

Enhanced fuel passageway and adapter combustion tool fuel cell

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.

Actuation structure for internal fuel cell metering valve and associated combustion tool

An adapter configured for use in combination with a cap on a fuel cell having a closure formation, the cap having at least one leg portion and a corresponding foot extending from the leg, including a ring portion configured for engagement upon the closure formation of the fuel cell and including a top edge, a bottom edge, and a sidewall therebetween having an inner sidewall and an outer sidewall, a grooved portion defined by the inner sidewall, a convex gripping formation on the outer sidewall complementary to the closure formation, and at least one recessed formation adjacent the grooved portion for receiving the foot.
