Apparatus for mixing a second fluid into a first fluid comprising a flow path (13) of the first fluid, having a first inlet (11) for receiving the first fluid and a second inlet (14) arranged downstream of the first inlet (11) for receiving the second fluid, an outlet (12) for discharging a mixture of said first fluid and said second fluid, a vertically adjustable throttle body (22) having a second end comprising an end portion (27), wherein the throttle body (22) is arranged for controlling the flow area of the flow path (13) and is adjustable so that the flow area of the flow passage (13) decreases with a decreasing flow rate of the first fluid and increases with an increasing flow rate of the first fluid. The end portion (27) of the throttle body (22) comprises three parts, wherein the first part (28) and the third part (30) are protrusions and the second part (29) is an indentation. |
