A combustion chamber assembly for use in a combustion-powered fastener driving tool, includes a cylinder body, a reciprocating probe assembly slidably disposed relative to the cylinder body between a first, extended position and a second, retracted position, and at least one shock-absorbing member operationally associated with at least one of the cylinder body a n d the probe assembly for reducing shock load generated by the tool during combustion and transmitted between the probe assembly and the cylinder body. In another embodiment, a single spring disposed between the probe assembly and the cylinder body is configured for biasing the probe assembly into the first position.

A constant volume metering chamber and valve assembly for use with a pressurized fluid supply containing a fluid is described for use in a power fastening tool. The assembly includes a first spring-biased valve and a second spring-biased valve. There is a metering chamber having an inlet and an outlet, so that the first spring-biased valve controls the inlet and the second spring-biased valve controls the outlet. An actuator assembly operates causes the first and second spring-biased valves to move in either a first valve sequence or a second valve sequence. The first valve sequence includes engaging the first spring-biased valve with the inlet, preventing flow of the fluid from the fluid supply into the metering chamber, followed by disengaging the second spring-biased valve from the outlet, allowing flow of the fluid from the metering chamber. The second valve sequence includes engaging the second spring-biased valve the said outlet, preventing flow of the fluid from the metering chamber, followed by disengaging the first spring-biased valve from the inlet, allowing flow of the fluid from the fluid supply into the metering chamber, such that fluid is prevented from flowing freely from the pressurized fluid supply through the inlet and the outlet of the metering chamber.
摘要:
A combustion powered tool has a self-contained internal combustion power source constructed and arranged for creating a combustion for driving a driver blade to impact a fastener and drive it into a workpiece. The tool includes a housing constructed and arranged to enclose the power source, a combustion chamber defined at an upper end of the housing and a cylinder disposed be in fluid communication with the combustion chamber. A valve member is disposed to periodically close the combustion chamber. A piston is associated with the driver blade and is configured for reciprocal movement within the cylinder between a start position and a driving position. Also included on the tool is a nosepiece having a workpiece contact element configured for contacting a workpiece. The workpiece contact element is movable relative to the nosepiece, and upon such contact, the movement of the workpiece contact clement causes the valve member to close the combustion chamber. A delay apparatus is engageable with the workpiece contact element and the linkage for delaying the opening of the combustion chamber by the valve member until the piston returns to the start position after driving the fastener.
