摘要： A device for regulating the flow in a breathing gas apparatus includes a baffle in a housing which is pivotable toward and away from an interior cylindrical wall in order to vary the quantity of air which is directed through a passage defined between the baffle and the wall and into a slot forming an inhalation discharge port which leads to the user of a respiratory device. The baffle may be shifted in the housing by an adjustment means, in the form of a threaded member, to regulate the amount of breathing gas which is directed from the inlet port directly to the slot forming the inhalation discharge port, and the amount which is circulated around the housing when the baffle is moved away from the wall for indirect flow to the uncovered portion of the inhalation discharge slot.
