Opening claim text (preview).
What is claimed is: 1. A slow response time tool comprising: a biasing arrangement arranged to bias the tool to a second position from a first position, the biasing arrangement including a release member preventing the biasing member from moving until released by a threshold fluid pressure; a piston in operable communication with the biasing arrangement the piston positioned to resist movement of the biasing arrangement; a chamber receptive to the piston; a retardation arrangement defining a helical pathway in fluid communication with the chamber, the helical pathway providing a time delayed escape path for fluid from the chamber thereby resisting piston movement into the chamber, resisting movement of the biasing arrangement and resisting movement of the tool to the second position, thereby slowing response time of the tool after an actuation event. 2. The tool as claimed in claim 1 wherein the biasing arrangement is a spring. 3. The tool as claimed in claim 1 wherein the piston comprises a helix piston and a helix piston mandrel that together form the retardation arrangement. 4. The tool as claimed in claim 3 wherein the helix piston mandrel includes a helical upset thereon. 5. The tool as claimed in claim 4 wherein the upset is a thread. 6. The tool as claimed in claim 4 wherein the helical upset defines a crest and the helix piston bridges the crests of the upset to form the helical pathway. 7. The tool as claimed in claim 1 wherein the retardation arrangement is a fluid pressure drop arrangement. 8. The tool as claimed in claim 1 wherein the fluid pathway has a hydraulic diameter of 0.030 inches or greater. 9. The tool as claimed in claim 1 wherein the fluid pathway has a cross sectional flow area of greater than or equal to 0.003 square inches. 10. The tool as claimed in claim 1 wherein the helical pathway is through a housing surrounding the chamber. 11. The tool as claimed in claim 10 wherein the housing is a spring housing. 12. The tool as claimed in claim 1 wherein the helical pathway is through a connector to a housing surrounding the chamber. 13. The tool as claimed in claim 1 wherein the tool is a valve. 14. The tool as claimed in claim 13 wherein the valve includes a mandrel movable to uncover or cover ports in a ported housing connected to the tool. 15. The tool as claimed in claim 14 wherein the mandrel includes a profile configured for mechanical manipulation of the mandrel. 16. The tool as claimed in claim 1 wherein the release member is responsive to one or more of pressure, mechanical input, chemical activity, acoustic input, or temperature. 17. The tool as claimed in claim 1 wherein the retardation arrangement is a one piece component housing the helical pathway or path. 18. The tool as claimed in claim 17 wherein the retardation arrangement is additively manufactured.
