&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Diving regulator&amp;#039;&amp;#039;&amp;#039; is a pressure-regulating device that reduces pressurized breathing gas to ambient pressure and delivers it to the diver. The gas may be air or one of a variety of specially blended breathing gases. The gas may be supplied from a scuba cylinder carried by the diver or via a hose from a compressor or high-pressure storage cylinders at the surface in surface-supplied diving.&lt;br /&gt;
&lt;br /&gt;
== History ==&lt;br /&gt;
The concept of the diving regulator was first patented by [[Emile Gagnan]] and [[Jacques Cousteau]] in 1945. They developed the first [[Aqua-Lung]], a self-contained underwater breathing apparatus (SCUBA) that could supply divers with pressurized air, allowing them to stay underwater for longer periods of time.&lt;br /&gt;
&lt;br /&gt;
== Function ==&lt;br /&gt;
A diving regulator consists of one or more pressure-reducing valves, arranged in stages, with each stage reducing the pressure of the gas supply to a level more manageable or usable than the previous stage. The first stage reduces the cylinder pressure to a medium pressure and the second stage reduces the medium pressure to ambient pressure.&lt;br /&gt;
&lt;br /&gt;
== Types ==&lt;br /&gt;
There are two types of diving regulators: single hose and double hose. The [[single hose regulator]] is the type commonly used in recreational diving. It is called a single hose regulator because the diver breathes from it through a single mouthpiece, and the exhaled air is vented off to the surrounding water directly from the mouthpiece. The [[double hose regulator]] has two hoses, one for inhalation and one for exhalation.&lt;br /&gt;
&lt;br /&gt;
== Maintenance ==&lt;br /&gt;
Regular maintenance of a diving regulator is important for its longevity and for the safety of the diver. This includes regular cleaning, inspection for damage and wear, and periodic servicing by a qualified technician.&lt;br /&gt;
