I'm not going to argue with you - I haven't the foggiest what they are :) Sounds good, though ..

ROOTS manufactures a full line of low-pressure air and gas handling blowers, exhausters and systems. ROOTS has been in continuous operation since 1854 when the Roots brothers discovered the principle behind the rotary lobe blower. Since 1854 ROOTS has developed extensive experience with providing solutions for a wide range of applications.
As I say, not all of them have to be superchargers. FMI http://www.globaltecheng.com/roots.htm

What else could they be? http://auto.howstuffworks.com/supercharger2.htm 'Roots superchargers are really nothing more than air blowers, and the term "blower" is still often used to describe all superchargers.'

Not all Roots blowers are superchargers, though.

Hannah Je to pán Roots, respektíve bratia Rootsovi:
The Roots Blower Company was an engineering company based in Connersville, Indiana. It was founded in 1859 by the inventors Philander Higley Roots and Francis Marion Roots. It is notable for the Roots blower...

ne Vladimír, udělali smlouvu a ted je technický dodatek, chcete-li ale, tak to změním, pokud to půjde, díky

Vladimír Hoffman Jul 11, 2012:

Technicka poznamka Nemala by to skor byt otazka v kategorii Tech/Engineering?

Hannah Geiger (X) (asker) Jul 11, 2012:

no myslím že to tedy nenapsali v češtině příliš dobře, nezdá se vám....i přes to že nejsem expert přes dmychadla...

Gerry Vickers Jul 11, 2012:

Je to podstatné? http://en.wikipedia.org/wiki/Roots-type_supercharger

Hannah Geiger (X) (asker) Jul 11, 2012:
