The nozzle is a smooth and sharp cone tube. One end is connected to the entrance tube of the working water, and the other end is inserted into the room. Connected to the inhalation room is a mixed chamber composed of a conical tube (throat) and cylindrical tube. The extension of the expansion of the cross -section is connected to the mixed chamber, and the back end is connected to the discharge tube.

When working water flows with a certain pressure (0.3 to 21.5MPa), the pressure energy is transformed into kinetic energy, and the mouth is high (up to 25-50m / s), and That is, the air in the suction room) causes low pressure to generate the inhalation room. The inhaled liquid that is inhaled 7 inhaled the inhaled liquid entered the hybrid room 6 with the high -speed working water. The flow rate enters the voltage tube 5, and the part of the dynamic energy is converted to the pressure energy. It can be seen that as long as the working water is continuously available, the liquid that is pumped can be continuously pumped and sent.
