Abstract

See full text

An apparatus for mixing a first fluid into a flow path (44) of a second fluid, said apparatus having a chamber (12), which encloses the flow path and exhibits a first inlet (13) for receiving the second fluid, a second inlet (15) arranged downstream of the first inlet for receiving the first fluid, as well as an outlet arranged downstream of the second inlet for discharging a mixture of the first fluid and the second fluid, said flow path extending from the first inlet to the outlet and said second inlet opening into the flow path, a throttle body (29), which is pivotally arranged inside the chamber for controlling the flow area of the flow path, and pivoting means (50, 51) for pivoting the throttle body for said controlling of the flow area. According to the invention, the pivoting means is adapted to pivot the throttle body so that the flow area decreases with a decreasing flow rate of the second fluid and increases with an increasing flow rate of the second fluid, in order to maintain the flow velocity of the second fluid at the second inlet within a predetermined range.
