PROBLEM TO BE SOLVED: To provide a rectifier having a large effective cross section and high rectification performance.SOLUTION: A rectifier 10 disposed in a flow passage 26 through which fluid passes includes: a body 11 that is disposed in the flow passage 26, and has an inflow port 12 with which fluid flows in, an outflow port 13 with which fluid flows out and a communication passage 14 communicating the inflow port 12 and the outflow port 13; and a plurality of projections 15 that is disposed protrusively from the inner peripheral part of the communication passage 14 toward a center part, and extends along the communication passage 14. The projection 15 is formed into such a shape that the width of the center part is made narrower than that of the inner peripheral part of the communication passage 14 in a view from a fluid flow direction.SELECTED DRAWING: Figure 3 |
