ABSTRACT:
A fluid flow control device comprises first, second, and third fluid conduits. The first and second conduits are adapted to communicate with separate sources of pressurized fluid. The third conduit includes an inlet portion in direct flow communication with the first conduit and an outlet portion communicating with the atmosphere. A flexible wall forms an interface between portions of the second and third conduits. In response to fluid pressure fluctuations in the second conduit, the flexible wall simultaneously meters the flow communication through both the inlet and outlet portions of the third conduit. The fluid pressure in the first conduit is thereby elevated until substantial equilibrium with the fluid pressure in the second conduit occurs.
