Abstract
The pressure reading tool includes a housing with an interior chamber and an orifice extending from the chamber to the exterior of the housing. A pulse member with a magnetostrictive ring and an excitation source are disposed within the chamber to produce a highly agitated fluid discharge through the orifice. The magnetostrictive ring, chamber volume, and orifice cooperate to induce Helmholtz resonance frequencies in the fluid in the chamber to thereby enhance the agitation of the fluid discharge. A sheathing encapsulates the pulse member to protect it from contact with the fluid. A dampening element is also interposed between the pulse member and housing to isolate vibration.
Claims18
An apparatus for producing an agitated fluid discharge, comprising:
- a housing having a chamber with an orifice extending from said chamber to the exterior of said housing;
- and
- an annular pulse member surrounding the axis of said orifice and disposed within said chamber so as to agitate the fluid and direct a pressure wave in the fluid though said orifice.
An apparatus for producing an agitated fluid discharge, comprising:
- a housing having a chamber with an orifice extending from said chamber to the exterior of said housing and a dampening member at least partially lining said chamber;
- and
- a pulse member disposed within said chamber to agitate the fluid and direct a pressure wave in the fluid through said orifice, said pulse member comprising at least one magnetostrictive element disposed within said chamber and an excitation element to activate said magnetostrictive element.
An apparatus for producing an agitated fluid discharge, comprising:
- a housing having a chamber with an orifice extending from said chamber to the exterior of said housing;
- and
- a pulse member disposed within said chamber so as to modulate the volume of said chamber such that a pressure wave is created in fluid in said chamber and exits through said orifice, said pulse member including an annular pulse element surrounding the axis of said orifice and an excitation source electrically connected to said pulse element, said pulse element and excitation source cooperating to modulate the volume of said chamber.
