PROBLEM TO BE SOLVED: To provide valves for controlling flow along a fluid line.SOLUTION: A valve 100 includes an outer shell 110, and an inner housing slidably disposed in the outer shell that includes connector threads 114 surrounding a boss on one end and a passage including a tapered region within the boss. A shaft within the valve includes a base coupled to the outer shell, a tapered sealing pin disposed within the tapered region, and a fluid passage extending through the base to outlets in the sealing pin. A connector may be threaded into the one end of the inner housing, thereby slidably engaging the connector threads, camming elements on the inner housing causing the inner housing to move helically from a closed position where the sealing pin engages the boss to seal the outlets and an open position where the inner housing is directed away from the sealing pin to open a fluid path through the valve.SELECTED DRAWING: Figure 1A |
