  • Fluid flow regulator
    Patent number: 8225815
    Abstract: A fluid flow regulator includes a valve assembly defining a fluid passage. The fluid passage includes a first port, a second port, a sensing orifice disposed between the first and second ports, a first orifice disposed between the first port and the sensing orifice and a second orifice disposed between the sensing orifice and the second port. A first flow area of the first flow orifice varies in response to differential pressure across the sensing orifice as fluid flows through the fluid passage in a first direction from the first port to the second port. The first flow area is fixed as fluid flows through the fluid passage in an opposite second direction. A second flow area of the second orifice is fixed as fluid flows through the fluid passage in the first direction and varies as fluid flows through the fluid passage in the second direction.
