  • Vacuum pressure-adjusting apparatus
    Patent number: 6321772
    Abstract: The air (atmospheric air) is introduced from an atmospheric port, and it is throttled to give a minute amount by means of a bleed hole. The air is introduced into a vacuum chamber via a bleed passage, and it is introduced into a pressure regulator port via a feedback passage. Further, the air is allowed to pass through a space between a seat section and a seal member of a valve plug, and it is drawn toward a vacuum port. Thus, the seal member of the valve plug to be seated on the seat section is prevented from biting into the seat section.
