FLUID MACHINE

PROBLEM TO BE SOLVED: To provide a fluid machine capable of making uniform the flow in a downstream side of a delivery flow passage while restraining the pressure loss as the whole.SOLUTION: A fluid machine includes a body 20 acting on fluid, and a plurality of delivery flow passages 100 for guiding the fluid delivered from the body 20. In a first delivery flow passage 101 of the delivery flow passages 100, at least one portion P1 has a non-circular cross sectional shape, and in a second delivery flow passage 102 which is different from the first delivery flow passage 101 of the delivery flow passages 100, a portion P2 corresponding to the one portion P1 in the non-circular shape of the first delivery flow passage 101 has a cross sectional shape different from that of the one portion P1 of the first delivery flow passage 101.SELECTED DRAWING: Figure 2 【課題】全体として圧力損失を抑制しつつ、吐出流路の下流での流れを均一化させることが可能な流体機械を提供する。【解決手段】流体機械は、流体に作用する本体部２０と、本体部２０から吐出する流体を案内する複数の吐出流路１００を備え、複数の吐出流路１００の内の第一吐出流路１０１は、少なくとも一の箇所Ｐ１の断面が非円形形状とされていて、複数の吐出流路１００の内の第一吐出流路１０１とは異なる第二吐出流路１０２は、第一吐出流路１０１の非円形状となる一の箇所Ｐ１と対応する箇所Ｐ２の断面が第一吐出流路１０１の一の箇所Ｐ１の断面形状と異なる形状である。【選択図】図２
