Abstract
A solder-removing tool has a cylinder with a nozzle at one end thereof and a shaft with a piston assembly slidable in the cylinder. A latching assembly is disposed at the other end of the cylinder and latches the shaft in an extended position. A spring is fixed to a spring seat which is received on an annular flange of the cylinder near the latching assembly. A damping assembly employs a floating washer between the latching assembly and the spring seat, and employs a pair of exhaust ports and a compression port respectively formed through the latching assembly and the spring seat. The damping assembly absorbs the shock produced by the recoil of the spring from the extended position.
