Gas jet deflection in pressurized systems

A system comprising:

• a) a pressurized sub-system comprising:
• i) a higher pressure region, and
• ii) a lower pressure region;
• and
• b) a gas-deflector plate, wherein said gas-deflector plate comprises a top surface, a bottom surface, and a channel extending through said gas-deflector plate,
• wherein said gas-deflector plate:
• i) has longitudinal and lateral axes that extend through said gas-deflector plate that are parallel to said top and bottom surfaces, and ii) a vertical axis that is perpendicular to said longitudinal and lateral axes,
• wherein said gas-deflector plate is positioned between said higher pressure region and said lower pressure region such that said top surface faces said lower pressure region and said bottom surface faces said higher pressure region,
• wherein said channel comprises:
• i) a top opening in said top surface of said gas-deflector plate, and ii) a bottom opening in said bottom surface of said gas-deflector plate, and
• wherein said channel is shaped and/or angled such that jetting gas moving through said channel from said higher pressure region to said lower pressure region enters said lower pressure region at an angle offset from said vertical axis.
