Aqua-Lung, which was the first self-contained open-circuit underwater breathing system, has gained international fame and commercial success. This equipment is also known as the twin-hose diving regulator or demand valve. Aqua-Lung breathing apparatus has a basic structure similar to traditional scuba tanks. The regulator is connected via a demand valle, which regulates the flow air through the lungs.
Jacques Cousteau
Jacques Cousteau's aqua lung - A fascinating tale in Scuba Technology! The original Aqua lung was developed during World War II. Cousteau (a French national) developed the underwater breath apparatus in 1943. His inspiration came from a device perfected by Captain Yves Le Prieur in 1925. Although the Aqua-Lung was initially limited in functionality, the Germans eventually requisitioned gasoline to be used on the battlefield. Cousteau modified an existing regulator to develop the Aqualung and later invented the autonomous diving system.
Cousteau became an expert in scuba diving technology and went on to discover underwater archeology. In 1946, he led the first expedition using self-contained diving apparatus and recovered the Roman shipwreck Mahdia. In the following year, he converted a British minesweeper into an oceanographic research vessel. He was unable to raise funds and his passion for diving led him to write The Silent World, which became an award-winning film.
Aqua-Lung is the most important innovation in scuba diving. It was designed by Jacques Cousteau in 1959 and allows divers to safely and comfortably swim below water. The Aqua lung has been a popular tool, and Cousteau is responsible for the creation of many other tools that allow for oceanographic exploration. Cousteau actually invented the first underwater cameras in 1959. There's no question that Cousteau's innovations revolutionized the sport of scuba diving.
Emile Gagnan
In 1945, Emile Gagnan and Jacques Yves Cousteau patented their Aqua-Lung diving regulator. Aire Liquide, a French company, bought the rights to manufacture the regulator. The U.S. later purchased the rights to manufacture it. Divers Corporation. It was the latest development of the French CG45 regulator and was assembled in Canada. This regulator was 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 established in 1958 by Air Liquide, which purchased U.S. Divers. Air Liquide later acquired the company and made it the largest diving company worldwide. Aqua-lung is an integral part of almost all sets of Scuba gear today.
Two Frenchmen invented the Aqua-Lung: Emile Gagnan, and Jacques Cousteau. Both men served as spies during World War II for the French Resistance. After the war, Robert Ballard continued to pursue his interest in the sea. Emile Gagnan was a Frenchman who worked for L'Air Liquide. He eventually met Emile. They both learned how to use high pressure pneumatic design while engineers. Gagnan’s idea was realized into an fully-automated, compressed-air system for scuba diving called Aqua-Lung.
