ABSTRACT:
A vacuum controller for maintaining a defined vacuum pressure to a remote location, including a housing which defines a cavity. The controller includes means for connecting the cavity to the remote location, to a high vacuum, and to a control signal pressure. There is a cup-shaped plunger, having an opening in its side wall, which is adapted to reciprocate in the cavity, and there is a flexible diaphragm which seals between the housing and the plunger. The diaphragm also operates as a valving mechanism, such that, when the plunger moves in one direction, the diaphragm closes off the opening in the side wall of the plunger, and when the plunger moves in the other direction, it opens the opening. There is a check valve in said controller to prevent inversion of the diaphragms.
