Aqua-Lung, which was the first self-contained open-circuit underwater breathing system, has gained international fame and commercial success. This equipment is often referred to as the "demand valve" or "twin-hose diving regulator". Aqua-Lung breathing apparatus has a basic structure similar to traditional scuba tanks. The regulator is connected with a demand valve that regulates the flow and pressure of the air into the lungs.
Jacques Cousteau
Jacques Cousteau's aqua lung - A fascinating tale in Scuba Technology! The original Aqualung was created during World War II. Cousteau was a French national who developed the underwater breathing device in 1943. The device that Captain Yves Le Prieur invented in 1925 was Cousteau's inspiration. The Aqua-Lung initially had limited functionality. However, the Germans required automobile gas to use in battle. Cousteau took an existing regulator and created the Aqua-Lung. He also invented the autopilot diving system.
Cousteau discovered underwater archeology after advancing scuba tech. 1946 saw the first use of self-contained diving gear and the discovery of 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 invented by Jacques Cousteau (in 1959) and has allowed divers freedom of movement under 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. Cousteau's inventions revolutionized scuba dive.
Emile Gagnan
1945: Emile Gagnan (Jacques Yves Cousteau) and Emile Gaugnan (Emile Gagnan) patent the Aqua-Lung diving regulation. Aire Liquide, a French company, bought the rights to manufacture the regulator. It was later sold to the U.S. Divers Corporation. It was the latest version of the French CG45 regulatory and was built in Canada. This regulator was extremely successful.
Initially, the Aqualung was called Aqua-lung. The first Aqua-lung sold in France was in 1946. It was then brought to the United States in 1952. In 1958, Air Liquide purchased U.S. The company was renamed Aqua Lung America after it acquired U.S. Divers. Air Liquide eventually made the company a division and it is now the world's largest diving company. Aqua-lung today is a major component in nearly all Scuba Gear sets.
The Aqua-Lung was invented by two Frenchmen: Emile Gagnan and Jacques Cousteau. 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 was a Frenchman who worked for L'Air Liquide. He eventually met Emile. As engineers, they learned to use high-pressure pneumatic design. Gagnan's concept evolved into an automated compressed-air scuba diving system called the Aqua-Lung.
