MIDDLE SECTION

The Viböl  male and female middle sections are designed at specific angles in order to ensure that a perfect seal is achieved. The taper on the ball (male) fits on a different taper into the female section and allows for emission gas to form a second seal. The emission gas (diesel) is high in carbon, which, under heat and pressure turns to graphite. It is a known fact that graphite is the best antifriction agent. Therefore, the life of the Viböl's moving parts are extended.

Viböl  AXIAL, LATERAL, SWIVEL & TWISTING MOVEMENTS

1. AXIAL MOVEMENT - the lateral movement of the male section sliding in the female section of the Viböl . This movement occurs when the diesel engine torques under load and during gear changes. On initial pull-away, the time/movement is longer than the time/movement of the ensuing gear changes which can be measured in seconds. The arrangement of the 6 springs and the 2 flanges ensures the ball section in a central position, 10mminward, or 10mm outward. When the female is lengthened, then more axial movement can be achieved depending on application.

2. SEALING ABILITY - the male and female section of the Viböl  form a perfect seal and is lubricated by the emission gas (carbon) which forms graphite under heat and pressure. This formation of graphite limits wear, the carbon film ensures a further seal on the edges of the male ball section of the Viböl, ensuring no leakage of emission gas.

3. TWISTING & SWIVEL MOVEMENTS - the flanges on the Viböl are not fixed, therefore the twisting and swivel movements can be achieved. The spring arranged ensures that the Viböl returns to a neutral position every time a movement takes place. Due to vibration, uneven road surfaces, torque and gear changes, the Viböl is in constant movement absorbing the differentiation between the engine and the rest of the exhaust system.
