Title:
FLOW PATH DEVICE, FREEZING CYCLE DEVICE, PRESSURE PULSATION REDUCING DEVICE, AND PRESSURE PULSATION REDUCING METHOD
Document Type and Number:
WIPO Patent Application WO/2005/095875
Kind Code:
A1
Abstract:
[PROBLEMS] In a reduction in fluid pressure pulsation, a large space has been required for fluid expansion and larger pressure loss has been involved. [MEANS FOR SOLVING PROBLEMS] A pressure pulsation reducing device having a flow path through which pressure pulsation is transmitted, an inner tube placed in the flow path and constructed so that most part of fluid flowing inside the flow path flows around the inner tube, and small holes provided in the inner tube and expelling jet flows in the flow path by a pressure difference between the inside and the outside of the inner tube. The jet flows are expelled from the inner tube to a contracted flow section provided around the outer periphery of the inner tube to reduce pressure pulsation of the contracted flow section.
