Abstract:
1. A pressure regulator comprising: a housing assembly including a longitudinal center axis defining a fluid flow path from an inlet end to an outlet end substantially along said longitudinal center axis; a tubular plunger body supported within said housing assembly for linear movement toward and away from a valve seat in response to fluid pressure at said outlet end; a sleeve supported within said housing assembly and adapted to engage said tubular plunger body; and an actuator collar supported externally of said housing assembly and operatively attached to said sleeve such that rotation of said actuator collar about said longitudinal center axis in one direction from an open position produces linear movement of said sleeve and said tubular plunger body independent of the pressure at said outlet end, moving said tubular plunger body into engagement with said valve seat to a closed position, shutting off said flow path.
