Air flow regulator

摘要

Method and apparatus for air flow regulation comprise a vertically oriented tube and a sail assembly positioned in the tube and moveable therewithin responsively to air flow through the tube to regulate rate of air flow through the tube and stop air flow through the tube upon air flow rate through the tube exceeding a preselected value.

主权项

1. An air flow regulator, comprising:
a. a vertically oriented tube; b. a pair of open-ended telescoping tubular internal segments within the tube, an outer tubular segment being fixed and the other being slide ably movable along the fixed segment in the axial direction; c. a plate extending partially across the interior of the vertically oriented tube, positioned for contacting the movable one of the telescoping tubular segments and limiting travel of the moveable telescoping tubular segment, the plate covering an open upper end of the movable telescoping tubular segment upon contact therewith; d. a sail positioned in the vertically oriented tube below the telescoping segments; e. a strut connecting the sail and the moveable telescoping tubular segment; f. the baffle positioned to direct upward air flow within the tube into the telescoping tubular segments; the movable telescoping tubular segment moving vertically within the tube unitarily with the sail responsive to air flow upwardly through the tube against the sail.
