ABSTRACT:
Automatic portable unsolderer consisting of a solenoid supplied by alternating current, a cylinder whose piston has a rod consisting the core of said solenoid, including too a reservoir and a heating member, all of them axially engaged as above-mentioned. Through the heating member end, the material that has to be unsoldered is melted and through operation of the solenoid, the piston draws back and suctions said material, which is collected, in a solid condition, in the reservoir which includes a retaining member, easily removable, and a threaded plug. On the outlet of the reservoir a one-way valve is disposed so that the air compressed by the piston, through a return spring that encircles the rod, doesn't flow through the suction conduct avoiding in such manner that the air can drag soldering material particles. The ejected air is by-passed through a side hole provided with a one-way valve that is reversely oriented.
