Abstract
One or more embodiments of the presently described invention provide a vacuum pressure regulator including a spring, a knob, a housing, a chamber and a diaphragm. The spring encircles the knob and is capable of being compressed when the knob is rotated in one direction. The chamber and diaphragm are located inside the housing. A seal is formed when the compression of the spring creates a spring force that pushes at least a part of the diaphragm against a sealing surface of the chamber. This seal enables the chamber to maintain or hold a vacuum pressure for more than a transitory time period.
