Abstract: “QUARTER TURN CAM FOLLOWER MECHANISM FOR VALVE ACTUATION” The present invention discloses a quarter-turn cam follower mechanism (100) for valve actuation configured to regulate gas flow from a gas cylinder (106). The quarter-turn cam follower mechanism (100) includes a handle (108), a stem (216), a cam (208), a plunger (228), a second control element (124), and a stop mechanism. Rotation of the handle (108) causes corresponding rotation of the cam (208), in that a profiled cam surface converts rotational movement into linear displacement of the plunger (228). The linear displacement of the plunger (228) actuates the second control element (124) between closed, partially open, and fully open positions to regulate gas flow. A compression spring (230) maintains continuous engagement between the plunger (228) and the cam (208). The stop mechanism restricts rotational movement within approximately 90 degrees to provide controlled quarter-turn operation. (FIG. 2 For Publication)
