The swirl generator comprises a base 32, Fig.2, supported by radial struts 36 from a ring 37 and a nose portion 33 surrounded by a conduit 41 secured as by soldering between flanged rings 44, 45. The conduit 41 is made of a suitable non-magnetic flexible material and has axially-directed incisions 42 to provide resilient fingers 43 which at highflow rates flex outwardly, Fig.4 (not shown), to permit a part of the fluid to pass around the vanes. Thus although all the flow passes through the speed turbine 17 only part of it has swirl imparted thereto and the turbine 17 maintains a substantially uniform average swirl velocity for all flow-rates and provides a speed correction signal.

Title: Valves
IPC: F16K3/20
Filed: 1979-01-15
Abstract: The invention relates to guillotine dampers, particularly to those which are used to isolate a section of ductwork without the entire system requiring to be made inoperative. Known dampers of this kind suffer from the disadvantage that a satisfactory seal is difficult to establish around the periphery of the damper blade with the result that it can be hazardous in the isolated section if the remainder of the ductwork system is carrying toxic or otherwise dangerous fluids. According to the present invention, an auxiliary seal is provided in the form of first (10) and second (12) seals extending around the periphery of the duct on each side of the blade (2), which are urged towards each other and into sealing engagement with the blade (2) when in its closed position by means of a frame (20). The frame (20) is continuously urged to the sealing position by means of devices (36). Cams (52) act on the frame and are rotatable to selectively overcome the bias of the devices (36) and withdraw the frame to release the damper blade (2) for opening. <IMAGE>
