摘要：
A vacuum controller for isolating the vacuum chamber of a vacuum pump, the vacuum controller comprising a shell comprising an inlet and an outlet, the outlet being fluidly connected to the vacuum pump, a diaphragm disposed within the shell and defining a first cavity and a second cavity within the shell, the first and second cavities being on opposite sides of the diaphragm and the second cavity being in fluid communication with the outlet, a pressure balance module adapted to selectively fluidly connect the first and second cavities in an open configuration and a controller adapted to selectively actuate the pressure balance module wherein the diaphragm fluidly restricts at least one of the inlet and the outlet when the pressure balance module is in a closed configuration.
