Abstract
An integral regulator and gauge for a vacuum device consists of a circular regulator having the vacuum gauge inside thereof such that the regulator and gauge rotate about a common radial axis. An opening defined in a boss extending from the bottom of the regulator engages a sloped shoulder defined on the inside surface of a circular port in which the regulator is disposed, varying the size of an opening which allows air to bleed into the vacuum chamber to regulate the strength of the vacuum.
