Aqua-Lung, the world's first self-contained, open-circuit underwater breathing apparatus, gained worldwide fame and commercial success. This equipment is also called the twin-hose diver regulator, or the demand valve. Aqua-Lung breathing apparatus functions in a manner similar to a traditional Scuba Tank. The regulator is connected via a demand valle, which regulates the flow air through the lungs.
Jacques Cousteau
Jacques Cousteau and aqua lung - a fascinating story in Scuba technology! The invention of the original Aqua-Lung occurred during World War II. Cousteau, who was a French national, invented the underwater breathing apparatus in 1943. His inspiration was Captain Yves Le Prieur's 1925 device. The Aqua-Lung had limited functionality at first, but the Germans demanded that automobile gas be requisitioned to use on the battlefield. Cousteau adapted an existing regulator to create the Aqua-Lung, and then invented the autonomous diving system.
Cousteau, who had advanced scuba technology, went on to discover underwater archeology. He led the first self-contained diving expedition in 1946 and recovered the Roman shipwreck Mahdia. The next year, he made a British minersweeper an oceanographic research ship. Unfortunately, he was unable raise the funds to fund the expeditions. He eventually converted his passion for diving into The Silent World which became a popular film.
Aqua-Lung has been the most important innovation in diving. It was designed by Jacques Cousteau in 1959 and allows divers to safely and comfortably swim below water. Many people have made the Aqua-Lung a standard. Cousteau also helped to develop other tools for oceanographic exploration. Cousteau invented the first underwater cam in 1959. Cousteau s innovative innovations made scuba diving possible.
Emile Gagnan
In 1945, Emile Gagagnan and Jacques Yves Cousteau patented the Aqua-Lung diving regulator. Aire Liquide in France purchased the rights and manufactured the regulator. It was later sold by the U.S. Divers Corporation. It was the latest design of the French CG45 regulator. It was assembled in Canada. This regulator proved to be extremely successful.
Initially, the Aqualung (or Aqua-lung) was sold in France as the Aqua-lung. Then, it was brought to the U.S. in 1952. In 1958, Air Liquide purchased U.S. Aqua Lung America was created by divers and purchased by Air Liquide in 1958. The company eventually became a division of Air Liquide and is the largest diving company in the world. Today, the Aqua-lung is a major component of nearly every set of Scuba gear worldwide.
The Aqua-Lung was invented by two Frenchmen: Emile Gagnan and Jacques Cousteau. Both men were spies for the French Resistance during World War II. Robert Ballard maintained his love for the sea even after the war. Emile Gagnan became his partner in crime, and he was working at L'Air Liquide as a Frenchman. They were both engineers and learned how high-pressure pneumatic design works. Gagnan’s idea was realized into an fully-automated, compressed-air system for scuba diving called Aqua-Lung.
