    摘要: An automatic ventilator closure which operates on the basis of a pressure differential condition within the conduit is provided with an air flow detector to ensure that the control system for the closure does not cycle. The pressure sensor and air flow detector are both in the form of vanes that are integrally connected to each other.

    摘要: An automatic ventilator closure is described which operates on the basis of an over-pressure within the conduit leading up to the ventilator outlet. Electrical interlocks control a motor to place the closure in an open or closed condition.
