FIELD: pump engineering. SUBSTANCE: housing with mixing chamber and branch pipe for supplying passive fluid is provided with an active nozzle with inlet converging passage and outlet cylindric portions. The controller of flow of active fluid is mounted at the outlet cylindric portion of the nozzle and is made up as a cylindric body mounted for permitting rotation. The body is provided with opening, rod, and actuator. The diameter of the opening of the controller is equal to the diameter of the outlet portion of the nozzle. The plane of rotation of the axis of the opening is coincident with the axis of the nozzle and perpendicular to the longitudinal axis of the cylindric body. The inlet portion of the opening in the body is provided with the inlet directing converging passage with the inlet slot opening. The height of the passage in the plane perpendicular to the axis of the body is equal to the diameter of the opening. The side flat walls of the directing converging passage are parallel to the plane of the opening. EFFECT: enhanced capacity. 3 dwg
