In the vicinity of the outlet, the head 19 of the control vane 16 divides the flow into two streams A 1 and A 2 . Flows A 1 and A 2 flow through the curved surfaces 20 and 21 of the control vane 16, respectively.
The flow adheres to the flow, and downstream it merges into a straight flow A3 . At this time, the upstream ends 14 and 15 of the guide wall
are retreating outward from the nozzle tips 9 and 10, respectively, so that the flows A 1 and A 2 flow through the guide walls 12 and 1
The above-mentioned straight flow A 3 is realized without adhering to the flow A 3 .

る。 The flow B 0 flowing into the inlet section 4 flows through the nozzles 7 and 8.
The flow is split into two flows B 1 and B 2 by the head 19 of the control vane 16 near the exit of the flow. The flow B 1 is directed to the right by the nozzle 7 on the upstream side, but because the curved surface portion 20 of the control vane 16 is inclined to the left, the flow B 1 is directed toward the guide wall 12 on the downstream side of the nozzle 7. The flow becomes attached to the guide wall 12.
他方、流れB2は、ノズル８により左方に向か
う傾向を有した流れとして下流側では、流れB1

のである。 A central portion of the flow flowing into the inlet portion 4 flows out through the through groove 22 and becomes a straight flow C5 . The other part of the inflow flow is 2 at the curved surface part 20 of the control blade 16.
into streams C 1 and C 2 . Flows C 1 and C 2 are directed inwardly by nozzles 7 and 8, respectively, but the curved portion 20 in the control vane 16 is directed to the left for flow C 1 and to the right for flow C 2 . In order to direct the flow, each flow is directed towards the guide walls 12, 13. In this case, the flow
C 1 and C 2 are attached to the guide walls 12 and 13 separately, and the width of the jet is smaller compared to the case where they merge and maintain attachment to the guide walls as shown in Fig. 3. A stronger adhesion to the guide wall 12 or 13 is achieved than in the case shown. That is, flows C 1 and C 2 flow through the guide walls 12 and 12, respectively.
Since the flows C 3 and C 4 maintain adhesion up to the downstream end of 13, a wide-angle branched flow state is obtained.

Even when the pump is rotated counterclockwise, a similar deflection state can be achieved, that is, after passing through a rightward deflection, a straight flow and a wide-angle branch blowout state can be achieved.
