Supersoaker 100 (tm) Watergun (from Internet Glossary of Pumps)
Supersoaker 100 (tm) Watergun
The Larami Corporation of Philadelphia, PA patented an ingenious new type of watergun. It uses a high-pressure reservoir partially filled with air under pressure. This HYDRAULIC ACCUMULATOR had never been used in toy waterguns before.

A hand-operated piston forces first air, then water into the high-pressure reservoir (the circular ball.) Pulling the trigger releases a stream that can go 50 feet!

The trigger is a spring-loaded pincher which holds the vinyl tube shut. If you pump too much, pressure opens the trigger-valve and water dribbles out the nozzle, long before the high-presssure areas would burst.
