초록

A system, including a closed chamber (20) having a gas inlet (22) and a gas outlet (24) is shown and described. An inert gas supply under positive pressure is connected to the gas inlet, and a bubbler is connected to the gas outlet. The bubbler includes a compartment that is partially filled with liquid so as to define a head space, an inlet operatively connected to the gas outlet, a vent, and a vacuum line in fluid communication with the head space so that the head space has a negative pressure.

청구항

1. An apparatus for regulating pressure in a closed system, comprising: a) a compartment partially filled with a liquid so as to define a head space above the liquid;b) a vacuum port in fluid communication with the head space, so that an environmental pressure of the head space is negative;c) a vent line for regulating pressure in the head space, the vent line adjustably extending into the liquid;d) a process line including a first end connected to the closed system, and an opposing second end adjustably extending into the liquid. 2. The apparatus of cla...
