2. Schrader valve - Wikipedia

   en.wikipedia.org/wiki/Schrader_valve

   The Schrader valve is used on virtually all automobile tires and motorcycle tires and most wider-rimmed bicycle tires.In addition to tube and tubeless tires, Schrader valves of varying diameters are used on many refrigeration and air conditioning systems to allow servicing, including recharging with refrigerant; by plumbers conducting leak-down pressure tests on pipe installations; as a ...

3. Presta valve - Wikipedia

   en.wikipedia.org/wiki/Presta_valve

   There are adapters to fit a Schrader pump on a Presta valve, but loss/theft of the adapter can still be an issue. Adapters can leak, a disadvantage compared to a Schrader chuck on a Schrader valve. At very high speed - approximately 150 kph - Schrader valves can open under centrifugal force, leading to a flat tire.

4. Valve stem - Wikipedia

   en.wikipedia.org/wiki/Valve_stem

   Presta valves (also called Sclaverand valves or French valves) are normally only used on bicycles. The stem has a narrower diameter (nominally 6 mm) than the thinnest (nominally 8 mm) Schrader type, and so the bore of the hole in the rim through which the stem passes can be smaller. Has a locknut that needs to be opened to inflate/deflate. [17 ...

5. Dunlop valve - Wikipedia

   en.wikipedia.org/wiki/Dunlop_valve

   The Dunlop valve has a wider base than a Presta valve, similar enough in size to a Schrader valve to use identically drilled valve holes in rims, [3] but it can be inflated with a Presta valve adapter. [4] The inner mechanism of the valve can be replaced easily, without the need for special tools.

   A modified Schrader valve - with a floater - is used in self-acting vents on the very top of pipes. Via Schrader valves cooling medium is filled into the air conditioning of cars, small powder fire extinguishers are filled with nitrogen or pressure-checked. --Helium4 08:47, 8 August 2010 (UTC)

7. August Schrader - Wikipedia

   en.wikipedia.org/wiki/August_Schrader

   In 1849, he created a new copper helmet. Later, his interest in diving led to him to design an air pump. Around 1890, after reports of English cyclists' success using pneumatic tires, August Schrader saw the need for a bicycle tire valve. By 1891 he had produced the Schrader valve, which was his most popular invention and is used today. August ...
