ABSTRACT:
Diffuser apparatus comprises a frame including end portions interconnected by and integrated with an elongate intermediate portion. The intermediate portion is formed to produce a longitudinally extended trough, preferably of generally hemi-cylindrical configuration. The diffuser sleeve which mounts about and the length of the frame is longer than the frame and its excess length is used to provide reversibly bent extremities which produce a double layer of the sleeve thickness in areas thereof which overlie the frame end portions. The latter have circumferentially and longitudinally spaced ribs to which the double layered sleeve end portions are clamped to produce a positive and insured seal as between the sleeve and the frame at their end portions. One end portion of the frame has a through bore outwardly extended by an integral adapter to which a line connected to a source of fluid under pressure may be directly coupled. The discharge end of the bore which is innermost of the frame is intersected by aerodynamically shaped partitions arranged to smoothly divide a pressured flow of fluid into small jets which exit from the end portion to the chamber bounded by the sleeve and the intermediate trough-shaped portion of the frame. The surface in which the discharge end of the bore lies is inclined to and away from the base of the trough portion of the frame and mounts a reed type valve element a tongue-like portion of which depends over the inclined surface and the edges of the partitions in the bore which are innermost of the frame. The arrangement is such to insure an automatic seal of the bore in absence of the flow through the bore of fluid under a predetermined pressure.
