Abstract:
Method and apparatus for air flow regulation comprise a vertically oriented tube, 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 to stop air flow through the tube upon air flow rate through the tube exceeding a preselected value with a detector for sensing when the sail assembly has stopped air flow through the tube as a result of air flow rate exceeding said pre-selected value.
