摘要： A device for treating flowing working gases in order to reduce their operational noises and in most instances also to increase their operating efficiency comprises a flowing working gas operating device which has a discharge conduit with at least one discharge opening for the outflow of the working gas. A check valve is associated with the discharge and includes an elastic valve member movable to close the opening when the flow thereof decreases to a predetermined amount for example as determined by the reduction of pressure of the gases so as to prevent any back flow into the conduit which is likely to produce noise. The elastic member may comprise an ordinary rubber band which is preferably held in position by a guide member so that when the pressure of the working gas is sufficient the gases will flow out of the discharge conduit and will be directed through one or more chambers so as to cause the gas to flow into a whirling vortex flow and preferably in a substantially annular path so as to order the gases and to thereby increase their efficiency of operation.
