  • Patent number: 6382253
    Abstract: A fluid pressure reduction device for use with a fluid valve control member movable through the device. The pressure reduction device is formed of a plurality of stacked disks having an outer perimeter and an inner perimeter defined by a hollow center aligned along a longitudinal axis. The disks are formed in a cage assembly for receiving the fluid valve control member within the hollow center along the inner perimeter. The stacked disks include a plurality of longitudinal channels formed in the disk around the inner perimeter. Guide members formed of a metal harder or at least with greater wear resistant characteristics than the disks are provided in each of the longitudinal channels. The guide members are adapted to the inner perimeter for guiding the fluid valve control member in movements through the hollow center for reducing wear on the inner perimeter. It is preferred that the guide members comprise longitudinal rods inserted within each channel.
