Abstract
A swage fastening tool is disclosed, the tool including damper valve concentrically positioned about a piston which displaces the fastener being swaged. The damper valve moves with the piston when the trigger structure of the tool is actuated to supply pressurized fluid to the piston, the damper valve being positioned relative to the piston and the flow path of the fluid to meter flow both to the piston during swaging and from the piston after swaging has been completed. The trigger is provided with a camming feature to create a component of a trigger movement to actuate a flow control valve in a simplified manner and a self-restoring resilient arm portion to return the trigger structure to its initial position.
