PURPOSE:To enlarge the resistance ratio of a forward flow to a backward flow, by providing a disc with a plurality of guide blades on the peripheral portion of a fluid diode. CONSTITUTION:At the time of flowing forward, a fluid flows into from an inflow opening 11 and flows radially in the gap 16, then through a circular slit 15, flows into a liquid chamber 10 disposed on a disc 13 to flow out from an outflow opening 12. At the time of flowing backward, the fluid flows into the liquid chamber 10 through the opening 12. At this time, the velocity of flow decreases in the liquid chamber 10 to increase pressure of the liquid chamber 10, so that the fluid is about to flow through a gap 16 toward the inflow opening 11. At this time, the side walls of the liquid chamber 10 and guide blades 14 cause a tangential flowing in the fluid. |
