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.

Abstract: Disclosed is an inductive energy optimized vacuum solenoid valve, which comprises: a housing (1) with bobbin (2); a stationary fix core (10) fixed into the housing; a moving core (8) fitted between the bobbin and the fix core; a spring (9) housed in the moving core; a fix core insert (11) housed in the spring thereby forming a unit to maintain a constant distance between the moving core and fix core; at least one insert pin (12) made up of non-magnetic material extends from the fix core in a direction opposite to that of the fix core insert; and the inner diameter of the fix core of the vacuum solenoid valve is optimized in a range of 2.5 mm to 4.75 mm to maintain the lowest inductive load in the housing. The valve minimizes the switch off or inductive energy to such an extent so that it prevents sudden damage of an electric control unit in a motor vehicle from increased inductive load.
