Aqua-Lung gained worldwide popularity and commercial success as the first self-contained, opencircuit underwater breathing apparatus. This equipment is also called the twin-hose diver regulator, or the demand valve. The basic concept of Aqua-Lung breathing apparatus is similar to that of a traditional scuba tank. The regulator is connected and controlled by a demand valve.
Jacques Cousteau
Jacques Cousteau and aqua lung - a fascinating story in Scuba technology! The invention of Aqua-Lung, the first underwater breathing apparatus, was made during World War II. Cousteau, a French national developed the underwater breathing apparatus. His inspiration came from a device perfected by Captain Yves Le Prieur in 1925. Although initially the Aqua-Lung could only perform limited functions, the Germans ordered automobile gas for use on the battlefield. Adapting an existing regulator, Cousteau developed the Aqua-Lung and eventually invented the autonomous diving system.
After advancing scuba technology, Cousteau went on to discover underwater archeology. He led the first self-contained diving expedition in 1946 and recovered the Roman shipwreck Mahdia. The following year, he transformed a British minesweeper to an oceanographic research vessel. Unfortunately, he had difficulty raising the funds for the expeditions. Instead, he turned his passion to dive into The Silent World (which became a highly successful movie).
Aqua-Lung has been the most important innovation in diving. It was created by Jacques Cousteau and allows divers to swim comfortably and freely under water. The Aqua-Lung has become a staple for many people, and Cousteau helped develop many other tools for oceanographic exploration. Cousteau also invent the first underwater camera, which was invented in 1959. Cousteau’s innovations revolutionized scuba diving.
Emile Gagnan
In 1945, Emile Gagnan and Jacques Yves Cousteau patented their Aqua-Lung diving regulator. Aire Liquide, an American company, purchased the rights to make the regulator. Later, the U.S. sold it. Divers Corporation. It was the latest design of the French CG45 regulator. It was assembled in Canada. This regulator was extremely successful.
Initially, the Aqua-lung was called Aqua-lung. It was first sold in France in 1946. The Aqua-lung was later brought to America in 1952. In 1958, Air Liquide purchased U.S. The company was renamed Aqua Lung America after it acquired U.S. Divers. The company eventually became a division of Air Liquide and is the largest diving company in the world. Aqua-lung has become a major component of almost every set Scuba gear.
Emile Gagnan (France) and Jacques Cousteau (France) invented the Aqua-Lung. Both men served as spies during World War II for the French Resistance. Robert Ballard kept his interest in the ocean even after the war. Emile Gagnan, who was also a Frenchman working for L'Air Liquide, became his friend. They both learned how to use high pressure pneumatic design while engineers. Gagnan's ideas evolved into the Aqualung, a fully automated compressed-air diving system.
