METHOD AND APPARATUS FOR RESIN DELIVERY WITH ADJUSTABLE AIR FLOW LIMITER

摘要

Method and apparatus for air flow limiting comprise a vertically oriented tube, a sail assembly positioned in the tube and moveable therewithin responsively to air flow through the tube to limit rate of air flow through the tube and halt air flow through the tube upon air flow rate through the tube exceeding a preselected value, and a moveable stop for adjustably changing the length of travel of the sail assembly thereby changing the maximum amount of air flow.

主权项

1. An air flow limiter, comprising:
a. a vertically oriented tube; b. a pair of open-ended telescoping tubular segments within the tube, an outer tubular segment being fixed and the other being slideably 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 to limit travel of the moveable telescoping tubular segment, the plate covering an open upper end of the movable telescoping tubular segment upon contact therewith; d. an actuator connected to the plate for selectably limiting travel of said moveable tubular segment; e. a sail positioned in the vertically oriented tube below the telescoping segments; f. a strut connecting the sail and the moveable telescoping tubular segment; the movable telescoping tubular segment moving vertically within the tube unitarily with the sail responsive to upward air flow through the tube against the sail.
