GAS DRIVEN ACTUATION FEED TUBE FOR COMBUSTION POWERED FASTENER-DRIVING TOOL

摘要

A combustion tool having a gas actuated magazine advance includes a combustion chamber defined in part by a cylinder (40), a valve sleeve (38) axially reciprocating relative to the cylinder and an upper surface (48) of a piston (34), a pneumatically actuated magazine fastener mechanism (56), and an exhaust driven actuation feed tube (60) having a first end (62) configured for insertion into an opening in the cylinder in fluid communication with the combustion chamber and a second end (66) connected to the magazine fastener advance mechanism.
