Abstract
A pressure vessel includes a pump having a passage that extends between an inlet and an outlet. A duct at the pump outlet includes at least on dimension that is adjustable to facilitate forming a dynamic seal that limits backflow of gas through the passage.
Claims16
A pressure vessel comprising:
- a pump including a passage having a generally constant cross-sectional area between an inlet and an outlet and defined on two sides by respective belts that are moveable along the passage;
- and
- a duct at the outlet and having a predetermined cross-sectional area that is approximately equal to the cross-sectional area of the passage, wherein the duct and the passage of the pump both include non-circular cross-sections.
A pressure vessel comprising:
- a passage extending between a low pressure inlet and a high pressure outlet, the passage having a generally constant cross-sectional area between the low pressure inlet and the high pressure outlet, the passage being defined on two sides by respective belts that are movable along the passage, wherein the passage has four sides and a non-circular cross-section;
- and
- a dynamic seal within the passage and consisting essentially of consolidated particulate material, wherein the dynamic seal is within a duct at the high pressure outlet of the passage and the duct defines a length, a uniform width along the length and a uniform depth along the length, at least one of which is adjustable.
