An inner tube is an inflatable torus that forms the interior of some pneumatic tires. [1] The tube is inflated through a valve stem and fits inside the tire casing. The inflated inner tube provides structural support and suspension, while the outer tire offers grip and protects the more fragile tube.
A tubeless tire (also spelled as tubeless tyre in Commonwealth English) is a pneumatic tire that does not require a separate inner tube.. Unlike pneumatic tires which use a separate inner tube, tubeless tires have continuous ribs molded integrally into the bead of the tire that are forced by air pressure into a flange on the metal rim of the wheel, sealing the tire to the rim.
The Dunlop valve, (also called a Woods valve, an English valve or a Blitz valve [1]) is a type of pneumatic valve stem in use—mostly on inner tubes of bicycles—in many countries, including Japan, [2] Korea, India, Pakistan, Sri Lanka, most European countries, and a number of developing countries.
This tractor was of a completely new design, with a 6-inch (150 mm)-inch bore and a 9-inch (230 mm) stroke (= 4.17 litres). There were many smaller modifications such as a redesigned injection pump and cylinder head. In 1938 the 12/20 model was redesigned and the model coding was changed so that the new model became the Marshall Model "M" tractor.
In 1898, bicycle manufacturer Walter Lorenzo Marr in the United States built a motorised tricycle powered by a single-cylinder OHV engine. [7] Marr was hired by Buick (then named Buick Auto-Vim and Power Company) from 1899–1902, where the overhead valve engine design was further refined. [8]
