Aqua-Lung is the first open-circuit, self-contained underwater breathing device. It has enjoyed worldwide success and fame. This equipment is commonly known as the twin-hose regulator or 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 & aqua lung – A fascinating story in Scuba Tech! The invention of the original Aqua-Lung occurred during World War II. Cousteau, a French national developed the underwater breathing apparatus. He was inspired by a 1925 invention by Captain Yves Le Prieur. While the Aqua-Lung was initially a limited-functioning device, the Germans requisitioned automobile gas to use on the battlefield. Adapting an existing regulator, Cousteau developed the Aqua-Lung and eventually 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 struggled to raise the funds for the expeditions and he eventually turned his passion for diving into a book called The Silent World, which became a successful film.
Aqua-Lung, the most significant innovation in scuba dive is Aqua-Lung. Developed by Jacques Cousteau in 1959, it has allowed divers to swim freely and comfortably under water. The Aqua-Lung has been a common tool for many, and Cousteau contributed many other tools to oceanographic exploration. Cousteau invented the first underwater cam in 1959. There's no question that Cousteau's innovations revolutionized the sport of scuba diving.
Emile Gagnan
In 1945, Jacques Yves Cousteau and Emile Gagnan 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. It was then brought to the United States in 1952. In 1958, Air Liquide purchased U.S. Divers and changed the company's name to Aqua Lung America. 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 spy for the French Resistance during World War II. Robert Ballard kept his interest in the ocean even after the war. He eventually met Emile Gagnan, a fellow Frenchman who was working for L'Air Liquide. Engineers, they were able to learn high-pressure pneumatic design. Gagnan’s idea was realized into an fully-automated, compressed-air system for scuba diving called Aqua-Lung.
