FIG. 1 is a partially cutaway perspective view showing an embodiment of the present invention, and FIGS. 2 and 3 are half-cut perspective views showing a conventional example. 2... Rotating shaft, 12... Annular body, 14... One end surface, 16... Outer peripheral surface, 18... Groove.
Claims (1)
にかけて軸方向に延びる複数の溝を周方向等配状
に設け、各溝は、上記一端面から見た形状が略半
円形であつて、軸線を通る平面で切断した断面が
上記一端面側において軸線と平行に延びるととも
に軸方向中途から上記外周面へ向けて円弧状に立
ち上がる略船底形をなすパーシヤルインペラー。 A plurality of grooves extending in the axial direction from one end surface of the annular body attached to the rotating shaft to the outer circumferential surface are provided at equal intervals in the circumferential direction, and each groove has a substantially semicircular shape when viewed from the one end surface, A partial impeller whose cross section taken along a plane passing through the axis extends parallel to the axis on the one end surface side and rises in an arc shape from the middle in the axial direction toward the outer circumferential surface, forming a substantially ship bottom shape.
