ABSTRACT:
A vacuum pump for a desoldering iron gun which comprises a cylinder closed at one end with a piston movable in the cylinder, and device including a valve connecting the closed end of the cylinder to the gun. A spring normally urges the piston away from the closed end of the cylinder, and drive linkage connects the piston to a motor for moving the piston toward the closed end of the cylinder against the urging of the spring. Latch device holds the piston in position adjacent the closed end of the cylinder. Trip device for releasing the latch is operated by the same motor. Operation is initiated by a switch on the gun that starts the motor, causing the trip mechanism to release the latch, and the spring to force the piston away from the closed end to produce a partial vacuum. The motor continues to run through its cycle, again compressing the spring and moving the piston back to its latched position.
