Abstract

This design utilizes a bellows-piston arrangement for a solder fountain, as shown in the drawing, which;, 1. Provides positive isolation of the molten solder from the hot heater area and driving shaft-guide bushing area. 2. Provides a low-friction arrangement free of lubricant in the molten solder area and exit port area. 3. Provides a low minimal friction piston arrangement for a smooth pumping unit with a high-capacity solder volume which is adjustable.

Solder Fountain Design

This design utilizes a bellows-piston arrangement for a solder fountain, as shown in the drawing, which;,
1. Provides positive isolation of the molten solder from the hot

heater area and driving shaft-guide bushing area.
2. Provides a low-friction arrangement free of lubricant in the

molten solder area and exit port area.
3. Provides a low minimal friction piston arrangement for a

smooth pumping unit with a high-capacity solder volume which

is adjustable.

The driving shaft 1 pushes the low friction-high temperature plastic piston 2, which forces the molten solder out of the stainless cylinder 3 through the exit port
4. The molten solder is isolated from the high-heat region 5 and the carbon guide bushing 6 by stainless steel bellows 7. It should be noted that in the high- heat region 5 and carbon guide bushing area 6, no lubricant is needed or used, thus eliminating a basic maintenance problem.
