Explain how the vacuum valve is constructed.
What will be an ideal response?
The valve has a small disc backed up by a spring. Manifold vacuum pulls and holds the disc off its seat. Vacuum is allowed into the booster. When vacuum drops below the calibration of the spring, the spring moves the disc against its seat. When the disc is seated, the valve closes and does not allow vacuum to leak out of the system.
