Abstract
An apparatus for mixing a first fluid into a second fluid, comprising a housing having a flow-through chamber for the second fluid, a throttling body in the flow-through chamber, and inlet and outlet passages to enable flow of the second fluid to and from, respectively, the flow-through chamber. The throttling body is arranged with elements which are able to displace the throttling body between a position in which the throttling body blocks the inlet passage and a position in which the inlet passage is open. The apparatus is also provided with holes for introducing the first fluid, preferably into, or immediately in front of, the inlet passage.
