  • Control valve
    Patent number: 4327757
    Abstract: A fluid control valve is equipped with a plurality of sleeves nested one within the other to form a cage for pressure reduction between the inlet and outlet ports of the valve housing. Each sleeve is provided with blind bores, through-bores and interconnecting grooves which cooperate to repeatedly divide the flow into more and more partial flows which keep colliding with one another. Volume control is achieved by a slidable piston cooperating with the cage.
