Abstract:
1. A variable pressure regulator device, comprising: a valve body having a fluid inlet, a fluid outlet, a fluid pressure sensing chamber, and a valve seat in fluid communication with said inlet and defining an opening into said chamber, a resilient member forming a wall of said chamber and which is self-restoring; a valve stem extending from said resilient member towards said valve seat; a valve element supported by said valve stem and cooperating with said valve seat, said valve element being located between said valve seat and said inlet; and a fluid outlet pressure adjustment mechanism configured to contact said resilient member and define a portion of said resilient member which is responsive to pressure in said chamber to move said valve stem and said valve element relative to said valve seat between a open and a closed position, said adjustment mechanism comprising a cover defining an annular hand grip portion surrounding an outer periphery of a portion of said valve body and configured to permit said adjustment mechanism to be rotated relative to said valve body by hand to adjust a fluid outlet pressure of said device.
