Fluid sampling probe with vibration dampening
First Claim
1. An insertion assembly comprising:
- a housing having a passage formed therethrough having first and second ends, said first end of said passage formed to fluidly engage a pressurized fluid source;
a first retention nut having a probe shaft passage formed therethrough, said first retention nut having an outer diameter formed to threadingly engage said inner diameter of said housing passage in the vicinity of second end of said housing passage;
a second retention nut having a probe shaft passage formed therethrough, said second retention nut having an outer diameter formed to threadingly engage the said inner diameter of said housing passage;
a packing gland situated between said first and second retention nuts;
a threaded shaft having first and second ends, an outer diameter, and a length having a fluid passage formed therethrough, said threaded shaft extending through said probe shaft passages of said first and second retention nuts and through said first and second ends of said housing passage without contacting same, said threaded shaft forming a probe shaft;
wherein said packing gland directly engages said outer diameter of said threaded shaft so as to form a fluid barrier about said outer diameter of said threaded shaft; and
wherein said packing gland supports said probe shaft passage within said housing, so as to isolate said housing from said probe shaft.

Abstract
A system for insertion of a probe into a pressurized fluid stream by means of a threaded body formed to engage an elastomeric seal employed to form a fluid barrier thereabout. The present invention contemplates a system which effectively lessens resonance vibration effects and associated damage resulting there from in fluid sampling probes operating in high velocity fluid streams and the like, utilizing mechanical dampening properties associated with its seal(s) and insert(s), forming non-rigid attachment to support the length of the probe in a manner which facilitates resonance absorption and dampening, so as to lessen associated vibration/oscillation in the system. The threaded body forms, in effect, helical strakes to facilitate aerodynamic stabilization and reduce oscillations/vibration, as well as reduce force and deflection caused by high velocity fluid flow passing thereby.
