Abstract
A well bore servicing apparatus comprising a housing having a longitudinal axis and a through bore, and a movable member disposed in the housing, the movable member having a through bore and a fluid aperture therein, wherein the movable member is movable between a first stop position and a second stop position relative to the housing, wherein the fluid aperture is in fluid communication with the housing through bore and the movable member through bore to provide a fluid stream to the well bore in the first and second axially spaced stop positions.
Claims20
A well bore servicing apparatus comprising:
- a housing having a longitudinal axis and a through bore;
- a movable member disposed in said housing, said movable member having a through bore and a fluid aperture therein;
- a J-slot and lug disposed within said J-slot guiding relative movement between said movable member and said housing, wherein said J-slot is coupled to said housing and said lug is coupled to said movable member or vice-versa;
- an axially slotted member and a second lug dispensed in said axially slotted member, wherein said axially slotted member is rotatably disposed between said housing and said movable member
- wherein said movable member is movable axially and radially about a longitudinal wellbore axis between a first stop position and a second stop position relative to said housing;
- wherein said fluid aperture is in fluid communication with said housing through bore and said movable member through bore to provide a fluid stream to the well bore in said first and second axially spaced stop positions.

- a J-slot and lug disposed within said J-slot guiding relative movement between said movable member and said housing, wherein said J-slot is disposed between said housing and said movable member;
- and
- an axially slotted member and a second lug disposed in said axially slotted member, wherein said axially slotted member is disposed between said housing and said movable member;
- wherein said J-slot and said axially slotted member are selectively configurable to allow said movable member to move axially alone or axially and radially about a longitudinal wellbore axis between a first stop position and a second stop position relative to said housing;
- wherein said fluid aperture is in fluid communication with said housing through bore and said movable member through bore to provide a fluid stream to the well bore in said first and second axially spaced stop positions.
