Adjustable dampening device

Claim 1

A DEVICE FOR DAMPENING SHOCK IN THE FLUID OF A FLUID LINE COMPRISING THE COMBINATION OF A BODY MEMBER HAVING A BORE THEREIN AND AN INLET AND OUTLER COMMUNICATING WITH SAID BORE, A CORE MEMBER MOUNTED IN SAID BORE IN AXIAL ALIGNMENT THEREWITH AND BETWEEN SAID INLET AND OUTLET, THE EXTERNAL WALL OF SAID CORE MEMBER AND THE INTERNAL WALL OF SAID BORE HAVING A SPIRALLY DISPOSED FLUID PATH EXTENDING THEREALONG DEFINED BY A THREADED SURFACE FORMED ON ONE OF SAID WALLS AND AN UNTHREADED SURFACE ON THE OTHER OF SAID WALLS, THE CREST OF THE THREADS ON THE SAID THREADED SURFACE ENGAGING THE SAID UNTHREADED SURFACE, SAID FLUID PATH BEING DIVIDED BY A GROOVE IN THE CORE MEMBER AT A LOCATION INTERMEDIATE ITS ENDS INTO A PLURALITY OF SECTIONS ALONG SAID CORE MEMBER, BY-PASS MEANS COMMUNICATING WITH SAID GROIOVE AND EXTENDING THROUGH SAID CORE MEMBER FROM SAID FLUID PAT INTERMEDIATE SAID INLET AND OUTLET, SAID BY-PASS MEANS PROVIDING LESSER RESISTANCE TO FLOW OF FLUID THERETHROUGH THAN THROUGH SAID FLUID PATH, ADJUSTABLE GATE MEANS POSITINED ARTHWART SAID BY-PASS MEANS FOR SELECTIVELY CONTROLLING COMMUNICATION THROUGH SAID BY-PASS MEANS TO SELECT THE SECTIONS TO BE BY-PASSED THROUGH SAID BY-PASS MEANS FROM SAID FLUID PATH FROM SAID INLET TO SAID OUTLET, AND ACTUATING MEANS EXTENDING INTO THE BODY MEMBER AND CORE MEMBER FOR ADJUSTING THE OPERATIVE POSITION OF SAID GATE MEANS FROM THE EXTERIOR OF SAID BODY MEMBER.
