摘要：A valve for controlling gas flow to ventilator or physiotherapy apparatus, has a body having first and second inlet ports and an outlet port. A shutter plate is rotatable with respect to said body and adapted selectively to interconnect said inlet ports to said outlet port. Said shutter plate is operable on rotation in a single sense to connect alternately said first inlet port to said outlet port and said second inlet port to said outlet port.
