ACTUATOR SHAFT BOOT

Wastegated turbochargers all use actuators to manipulate the wastegate valve which controls turbine wheel bypass of exhaust gas energy. The diaphragms in these actuators are susceptible to foreign material damage. This damage is minimized by the addition of a boot around the actuator shaft, preventi...

Zusammenfassung:	Wastegated turbochargers all use actuators to manipulate the wastegate valve which controls turbine wheel bypass of exhaust gas energy. The diaphragms in these actuators are susceptible to foreign material damage. This damage is minimized by the addition of a boot around the actuator shaft, preventing ingress of foreign materials and fluids which could be detrimental to actuator life. Les turbocompresseurs à soupape de décharge utilisent tous des actionneurs pour manipuler la soupape de décharge qui régule l'énergie du gaz d'échappement contournant la roue de turbine. Les membranes de ces actionneurs sont susceptibles d'être endommagées par des matières étrangères. Cet endommagement est minimisé par l'ajout d'un protecteur autour de l'arbre de l'actionneur, ce qui empêche la pénétration des matières étrangères et des fluides qui pourraient nuire à la durée de vie de l'actionneur.
