An improved assembly for use in an in-line starter valve. A flexible material system in the form of a flexible belt is used to translate motion from a manually operable wrench shaft to a piston rod in order to render an in-line starter valve to a closed, partially opened, or an extreme opened position. When the wrench shaft is manually rotated, tension is imparted on the flexible band which, in turn, translates tension to a piston rod which then travels longitudinally resulting in the opening or closing of the in-line starter valve. An index mark on a handle of the wrench shaft indicates the closed, partially opened, or extreme opened position of the in-line starter valve. The use of the flexible belt affords greater durability, less weight, and less costly production than the prior art assemblies.

What is claimed is: 1. An in-line valve assembly comprising: a valve housing; a valve piston which may be received by a stationary valve piston seat, a piston rod coupled to said valve piston such that said piston rod and said valve piston are movable together relative to said stationary valve piston seat an air pressure chamber acting on said valve piston and operable to drive said piston rod and said valve piston; a manually operable wrench shaft coupled to said piston rod by way of a movable coupling such that when said manually operable wrench shaft is manually rotated, said piston rod and said valve piston are driven to travel together longitudinally; and when said piston rod and said valve piston are driven together longitudinally as a result of a pressure change in said air pressure chamber imparted to said valve piston, said manually operable wrench shaft is driven to rotate, wherein said movable coupling is a flexible material assembly. 2. The in-line valve assembly as recited in claim 1 whereby when said manually operable wrench shaft is rotated in a first direction to a first index mark said valve piston is driven to travel toward said stationary valve piston seat to render said in-line valve assembly in a closed position, and when said manually operable wrench shaft is rotated in a second direction opposite to said first direction to a second index mark said valve piston is driven to travel away from said valve piston seat to render said in-line valve assembly in an open position. 3. The in-line valve assembly as recited in claim 1 wherein said flexible material assembly comprises a flexible belt system. 4. The in-line valve assembly as recited in claim 3 wherein said flexible belt system includes a flexible belt that comprises a flexible frame portion having a frame opening whereby said frame portion is integrally connected to a flexible band segment such that said flexible belt may curve upon itself when installed for use as said movable coupling. 5. The in-line valve assembly as recited in claim 4 wherein said piston rod has a flattened side and said flexible belt has a first end and a second opposing end, whereby said flexible belt is attached to said flattened side of said piston rod at said first end and said second end. 6. The in-line valve assembly as recited in claim 5 wherein said flexible belt has a midpoint whereby said flexible belt is wrapped around and attached to said manually operable wrench shaft at said midpoint. 7. The in-line valve assembly as recited in claim 6 wherein said flexible belt is coated with an elastomer for damping. 8. The assembly for actuating a piston rod as recited in claim 6 wherein said piston rod has a flattened side and said flexible belt has a first end and a second opposing end, whereby said flexible belt is attached to said flattened side of said piston rod at said first end and said second end, and said flexible belt has a midpoint whereby said flexible belt is wrapped around and attached to a bushing which is configured to securely receive said manually operable wrench shaft. 9. The in-line valve assembly as recited in claim 5 wherein said flexible belt has a midpoint whereby said flexible belt is wrapped around and attached to a bushing which is configured to securely receive said manually operable wrench shaft. 10. The in-line valve assembly as recited in claim 4, wherein a portion of said flexible belt which is attached to said wrench shaft is formed to be at a distinct location along an axis of said manually operable wrench shaft relative to a portion of said valve piston which is attached to said piston rod such that said flexible belt may wrap around said manually operable wrench shaft without overlapping said portion of said flexible belt which is attached to said piston rod. 11. The in-line valve assembly as recited in claim 10, wherein said portion of said flexible belt which is attached to said piston rod has upper and lower portions spaced on each side of a portion of said flexible belt which is attached to said manually operable wrench shaft along said axis of said manually operable wrench shaft. 12. in-line valve assembly as recited in claim 3, wherein said flexible belt system is fanned of a textile material. 13. The in-line valve assembly as recited in claim 3, wherein said flexible belt system is formed of a metallic material. 14. The in-line valve assembly as recited in claim 1, wherein said in-line valve is a starter valve for an engine. 15. An assembly for actuating a piston rod comprising: a piston rod selectively movable by air pressure in a chamber; a wrench shaft perpendicular to and movably coupled to said piston rod by way of a movable coupling such that a rotation of said wrench shaft translates longitudinal motion to said piston rod wherein said movable coupling comprises a flexible belt system, and when said piston rod is caused to move by the air pressure, said piston rod causing said wrench shaft to rotate through said flexible belt system. 16. The assembly for actuating a piston rod as recited in claim 15, wherein said flexible belt system includes a flexible belt that comprises a flexible frame portion having a frame opening whereby said frame portion is integrally connected to a flexible band segment such that said flexible belt may curve upon itself when installed for use as said movable coupling. 17. The assembly for actuating a piston rod as recited in claim 16, wherein said piston rod has a flattened side and said flexible belt has a first end and a second opposing end, whereby said flexible belt is attached to said flattened side of said piston rod at said first end and said second end, and said flexible belt has a midpoint whereby said flexible belt is wrapped around and attached to said wrench shaft at said midpoint. 18. The in-line valve assembly comprising: a valve housing; a valve piston which may be received by a stationary valve piston seat, a piston rod coupled to said valve piston such that said piston rod and said valve piston are movable together relative to said stationary valve piston seat; a manually operable wrench shaft coupled to said piston rod by way of a movable coupling such that when said manually operable wrench shaft is manually rotated, said piston rod and said valve piston are driven to travel together longitudinally; when said piston rod and said valve piston are driven together longitudinally as a result of a pressure change imparted to said valve piston said manually operable wrench shaft is driven to rotate, wherein said movable coupling is a flexible material assembly; said flexible material assembly comprises a flexible belt system, said flexible belt system including a flexible belt that comprises a flexible frame portion having a frame opening whereby said frame portion is integrally connected to a flexible hand segment such that said flexible belt may curve upon itself when installed for use as said movable coupling; said piston rod has a flattened side and said flexible belt has a first end and a second opposing end, whereby said flexible belt is attached to said flattened side of said piston rod at said first end and said second end; said flexible belt has a midpoint whereby said flexible belt is wrapped around and attached to said manually operable wrench shaft at said midpoint; and said flattened side of said piston rod is provided with an elastomer backing for damping.
