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

A combustion tool having a gas actuated magazine advance, comprising:
- a combustion chamber defined in part by a cylinder, a valve sleeve axially reciprocating relative to the cylinder and an upper surface of a piston;
- a pneumatically actuated magazine fastener advance mechanism;
- and
- an exhaust driven actuation feed tube having a first end configured for insertion into an opening in the cylinder in fluid communication with the combustion chamber and a second end connected to said magazine fastener advance mechanism.
A gas driven actuation tube for a combustion tool with a combustion chamber defined in part by a cylinder and a valve sleeve axially reciprocating relative to the cylinder, the combustion tool also provided with a pneumatically actuated magazine fastener advance mechanism, said tube comprising:
- a first end being angled relative to a longitudinal axis and configured for insertion into an opening in the cylinder in fluid communication with the combustion chamber;
- a sleeve portion axially adjacent said first end and configured for disposition between an exterior of the cylinder and an interior of the valve sleeve so that the valve sleeve freely reciprocates relative to the cylinder;
- an exhaust portion axially adjacent said sleeve portion and forming a general “C” shape around an exhaust valve of the tool;
- and
- an actuation portion axially adjacent said exhaust portion and configured for fluid communication with the magazine fastener advance mechanism.
