Device for generating a pulsed jet of fluid under pressure.

摘要

Abstract invention patent: "device to generate a pulsed jet of fluid under pressure. The present invention relates to a device (20) to generate a pulsed jet of fluid (16,18) of pressurized fluid.The device (20) contains a system of lines (36) which has at least a nozzle (38, 40) with a mouth to mouth (125) from which you can get out a jet of pressurized fluid (16). The device (20) has a chamber (22), in which is set a set pressure wave generator (24) to generate pressure waves in the fluid (32).The chamber (22) communicates with the system of lines (36) through an outlet (34) for the waves of pressure of fluid (32) is generated. According to the invention, the device (20) contains a set of readjustment (31, 47, 62, 64) for the control of the amplitude AP of the pressure waves of fluid (22) in the system of line (36) in front of at least one mouth to mouth (125).With the combination of readjustment (31, 47, 62, 64) can be rearranged a Helmholtz number I: = L /? A quotient of the extension path L for the waves of pressure of fluid (22) between the outlet (34) of the chamber (22), and at least one mouth to mouth (125) of at least one nozzle (38),40) in the system of line (36) and the compliance? The pressure waves of fluid (22) in the system of lines (36).
