  Schrader valve - Wikipedia, the free encyclopedia
The Schrader Valve is a valve stem invented by August Schrader and is used on virtually all automobile tires and lower pressure bicycle tires.
It is a poppet valve assisted by a spring.
Schrader valves are also used on the fuel rail of some direct fuel injection engines and on some automotive air conditioning systems, in a diameter larger than those used on tires, to allow recharging with refrigerant.

 Presta and Schrader Valves
The Schrader valve stem is recessed, lacks the locking nut and normally uses a spring to help keep it closed.
There is a common misconception that Presta valves are better for the higher pressures used in high performance bicycle tires, but Schrader valves are used in many high pressure industrial applications, as well as high pressure bicycle suspension systems.
In the photo to the left are two different types of Schrader valve cores, a "long" core which has a relatively large exposed spring, and a "short" one with an internal spring that isn't visible.

 Valve connector patent invention   (Site not responding. Last check: 2007-11-04)
The last mentioned valve type is frequently used on common cars, where a spring-loaded pin head in the valve plug must be kept down in preparation of the passage of air, while pumping a tyre.
With reference to different valve diameters, it is necessary, that auxiliary equipment (nut 6) is screwed onto or out of the valve thread to reduce or increase the internal diameter in advance to ensure the establishment of a connection from the valve connector to other valve diameters.
Tightening occurs against the core of the valve thread and is stabilized as a result of the reduced radius of the inner part of the gasket seal.

 Presta vs Schrader valves by Jobst Brandt
Many valve types have come along since the invention of the pneumatic tire but for bicycles mainly Presta and Schrader remain in use.
The Presta valve is the more slender of the two and is slightly more cumbersome to use, having a lock nut instead of a spring to ensure closure.
The small diameter of the Presta valve requires a smaller hole in the rim, whose size is important for narrow rims where cross sectional strength of is significantly reduced by a stem hole.

 Automotive Tire Valves (ZIGGURAT) from TIREX International
The Duryea brothers were the first car manufacturers in America to put pneumatic tires on their horse-less carriage; and if it hadn’t been for the invention of the tire valve by August Schrader and his son, George, there wouldn’t have been an air-tight seal to keep the tires from going flat over time.
George Schrader is credited with the pioneering effort and experimental work that resulted in patents issued for the current housing design with its removable and interchangeable core and cap.
Two years later Schrader and his son, George, applied for their first patent on the Schrader tire valve, improvements of which became the standard for the world and the nucleus for their company’s success.

 Valves for Bicycle Applications at Yellow Jersey

These were common when valves were not as uniformly well made as today.
When John Howard was attempting a land speed record with a motorpaced bicycle, the Schrader valves opened when the speed was sufficient to depress the pin - the pin's mass overcame the spring - a problem solved with real Schrader metal caps with rubber liners.

 valve stems - 'BentRider Online Forums
The Presta stem is thinner than the Schrader, and it has a small captive nut at the end that you must unscrew before attaching the pump head.
Some pumps have heads with fittings for both valve stems, and others can be switched between the two, usually by removing a fitting, turning it around, and reinstalling it into the head.
One thing in the Schrader valve's favor is that it is much easier to find tubes in the 20" size with Schrader valves rather than Presta.
