Abstract:
Apparatus comprising:a pressure regulator body having an inlet port and and an outlet port;a pressure regulator valve disposed in said pressure regulator body, said valve being moveable between an open and a closed position and being responsive to open or close the valve based at least in part on a differential pressure between the pressure in the outlet port and the pressure in the inlet port;a chamber in the pressure regulator body on the outlet port side of the valve; anda conduit having a fluid passageway therein extending from said outlet port into said chamber, said conduit having an inside and an outside and having an open end forming part of said fluid passageway, said open end being spaced from said valve thereby creating flow through the entire length of said conduit directly from the valve to said open end and pulling fluid which is located radially outwardly from said conduit in said chamber from said open end, through the inside of the conduit to said outlet port, thereby reducing the pressure in said chamber and causing a vacuum assist effect.
