Abstract
A circularly symmeterical casing is deformable between a maximum flow section and a minimum flow section, making it possible to increase the pressure of the air passing through casing from a minimum pressure for the maximum flow section to a maximum pressure for the minimum flow section. The invention makes it possible to obtain a fluid jet of substantially constant range.
Claims21
Apparatus for delivering a fluid jet of substantially constant range, comprising:
- a) a confinement duct for confining a compressible fluid, which duct is open at both its upstream end and downstream end;
- b) at its downstream end, at least one compressor device for compressing said fluid, which compressor device comprises a deformable casing that is deformable between a maximum flow section and a minimum flow section;
- and
- c) at its upstream end, said confinement duct comprises at least one head loss member constructed to adjust the head loss of the incoming fluid,
- thus increasing the pressure of the fluid passing through the casing from a minimum pressure for a maximum flow section to a maximum pressure for a minimum flow section, by modifying value of the pressure of the fluid at the outlet of the apparatus, and thereby providing a pressure in the fluid at the outlet of the apparatus that is variable starting from an incident flow of substantially constant pressure.
