Title:
NOISE DAMPENING MODULE FOR A VACUUM MODULATOR IN A MOTOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2014/174454
Kind Code:
A3
Abstract:
The present invention relates to a noise dampening module for a vacuum modulator in a motor vehicle. More particularly, this invention relates to an improved design of vacuum modulator or electronic vacuum regulating valve (EVRV) wherein the said noise dampening module has been implemented by using sponge or alike material. There is always an air gap between the plunger and inner core of the vacuum modulator. This air gap creates noise due to metal to metal contact and noise intensity increases further during vehicle off-on condition. This air gap is eliminated by implementing a noise dampening module between the plunger and the inner core.
