Abstract:
1. A vacuum pressure regulator including: a spring encircling a knob and capable of being compressed when said knob is rotated in a first direction: and a housing including a chamber and a diaphragm, wherein a seal is formed when compression of said spring creates a spring force that pushes at least a portion of said diaphragm against a sealing surface of said chamber, said seal enabling said chamber to maintain a vacuum pressure in said chamber wherein said housing includes a post having a screw thread configured to engage with a screw thread of said knob so that rotating said knob in said first direction causes said knob to move along said post towards a distal end of said knob and rotating said knob in an opposite direction causes said knob to move along said post towards a proximal end of said knob.
