Title (EN) NOISE FREE VACUUM MODULATOR IN A MOTOR VEHICLE
(FR) MODULATEUR DE DÉPRESSION EXEMPT DE BRUIT DANS UN VÉHICULE AUTOMOBILE
Abstract:
(EN) The present invention relates to an improved design of vacuum modulator or electronic vacuum regulating valve (EVRV) which completely eliminates the noise at emission system. The invention further introduces an improved design of the vacuum modulator which keeps the vacuum force balanced and makes the Vacuum Modulator Noise Free, more reliable and more durable. The noise free vacuum modulator of the present invention is resulted by the introduction of new design of internal filter, change in design of diaphragm, change in design of Cap, and change in design of Housing Sub Assembly.
(FR) La présente invention concerne une conception améliorée de modulateur de dépression ou de vanne de régulation électronique de dépression (EVRV) qui élimine complètement le bruit au niveau du système d'émission. En outre, l'invention concerne une conception améliorée du modulateur de dépression qui maintient la force de vide équilibrée et rend le modulateur de dépression exempt de bruit, plus fiable et plus durable. Le modulateur de dépression exempt de bruit de la présente invention est obtenu par l'introduction d'une nouvelle conception de filtre interne, un changement de la conception du diaphragme, un changement de la conception du couvercle, et un changement de la conception du sous-ensemble de logement.
