|
Reed Valves restrict the flow of fluids to a single direction, opening and closing under changing pressure on each face. Modern versions often consist of flexible metal or composite materials. All Reed Valve here are specifically designed to integrate into the complete composite technology and provide maximum performance and offer the most hunted reed valve accessories backed with guaranteed features that everyone can avail at incredible low prices. Reed valve system here will help increase the power and performance of every motorcycle or ATV. Find the comprehensive performance reed valves for a variety of all-terrain vehicle applications everyone's looking for.
V-Force Reed Valve
The Moto Tassinari VForce reed valve system is the number
one choice of the Factory teams. Currently more Factory race teams depend on their
reed valve technology than all the other brands combined. The newest advancement
in reed technology snaps together cage uses symmetrical reed petals, eliminating
the need for different "inner" and "outer" replacement petals. New reed tip shape
accelerates air mixture, ensured increased airflow for increased horsepower and
innovative design completely eliminates the need for screws.

Application
Two-Stroke Engine Reed valves are commonly used in high-performance versions of the two-stroke engine, where they control the fuel-air mixture admitted to the crankcase. As the piston rises in the cylinder a vacuum is created in the crankcase beneath the piston. This vacuum opens the valve and admits the fuel-air mixture into the crankcase. As the piston descends, it raises the crankcase pressure causing the valve to close to retain the mixture and pressurize it for its eventual transfer through to the combustion chamber. Composite materials are preferred in racing engines, especially (go karts, because the stiffness of the petals can be easily tuned, and they are relatively safe in failure (no metal fragments ingested by the engine). High-speed impact takes its toll on all reed valves, with metal valves suffering in fatigue. The physical inertia of reed valves means that they are not as entirely precise in action as rotary valves, opening slightly later than the optimum time. More sophisticated designs partly address this by creating multi-stage reeds with smaller, more responsive reeds within larger ones that provide more volume later in the cycle. Nevertheless, current technology favors reed valves almost to the exclusion of rotary valves due to their simplicity and low implementation costs.
