specific flow geometry 440 and specific to the movable element 400 shape in this example a movement communication duct 430 is disposed within the body 200 in fluid communication on one side with the movable element 400 and on another side in communication with the inner flow passage 152 fig5 a 2 is a section view of one example of the variable geometry nozzle 150 explained in the description of fig5 a 1 where the movable element 400 is in a different position interacting with the inner flow passage 152 causing a change of the flow passage geometry when compared to the flow passage geometry of fig5 a 1 fig5 b 1 is a section view of one example of the variable geometry nozzle 150 comprising a body 200 a movable element 400 disposed within the body 200 in one position where the flow geometry 440 generated by interaction of the movable element 400 and the inner flow passage 152 is of specific geometry when the movable element 400 is in this position the inner flow passage 152 is connected to the orifice 425 through a downstream passage 800 the downstream passage 800 is the location within the variable geometry nozzle 150 where the movable element 400 interact with inner flow passage 152 causing a change in the inner flow passage 152 geometry and causing the variable geometry nozzle 150 to have a specific flow geometry 440 and specific to the movable element 400 shape in this example a resilient element 405 is attached to the movable element 400 causing it to be biased in specific direction in this example a movement communication duct 430 is disposed within the body 200 in fluid.
