  • Pressure equilibrator for gases
    Patent number: 4827966
    Abstract: A pressure equilibrator has a slider received slidably in a pressure accumulation chamber and partitioning the chamber into two opposing sections, and a relief port formed in the inner side surface of the chamber. The slider is inserted into the pressure accumulation chamber with a minute gap left around the slider. Two gases are respectively introduced into the sections of the pressure accumulation chamber to be equilibrated in pressure. The gap provides passageways for connecting the respective sections of the pressure accumulation chamber with the relief port so as to discharge parts of the gases.
