A flow modulating device comprises flow modulating elements 8 of a shape memory alloy, which are acted upon by resilient elements 10. The flow modulating elements 8 and resilient elements 10 are mounted on a common support ring 6. At one temperature, the flow modulating elements 8 overcome the resilient force of the resilient elements 10 to lie against the wall of a duct 4 in which the device is situated. The flow modulating elements 8 thus offer a relatively low resistance to flow in the duct 4. At a second temperature, the force of the resilient elemen...
1. A flow modulating device for modulating flow in a duct, the device comprising: a first flow modulating element having a fixed end secured to a wall of the duct and a free end which is displaceable relative to the wall of the duct; anda first actuation element spaced from the first flow modulating element which only acts on the free end of the first flow modulating element, one of the first flow modulation element and first actuation element are made from a material exhibiting a shape memory effect and the other is a resilient element, wherein:the firs...
