Title:
流体減圧装置
Document Type and Number:
Japanese Patent JP4948488
Kind Code:
B2
Abstract:
A fluid pressure reduction device with low noise generation. A stack of annular disks with fluid passageways formed of inlet slots (36), outlet slots (38), and interconnecting plenums (40). Selectively stacking and orienting the annular disks along with an asymmetric slot pattern creates the desired fluid passageways without creating an uninterrupted axial fluid flow path. High recovery inlet stages are in fluid communicating series with low recovery outlet stages and the combination provides a high performance fluid pressure reduction device with low noise generation.
