Removal device with flow control

A removal device for removing gas bubbles and/or dirt particles from a liquid in a liquid conduit system, the removal device comprising:

• a main channel for a main flow, the main channel having an entry and an exit which are configured to be connected to the conduit system,
• a housing which defines an inner space, wherein the housing is arranged adjacent the main channel,
• at least one supply channel extending from the main channel to the inner space,
• at least one return channel extending from the inner space back to the main channel, and
• a branch flow control member positioned in the main channel, the branch flow control member being movable between a first position in which the branch flow control member is constructed to define a first path configured to branch off at least a part of the incoming main flow into the inner space via the supply channel, and a second position, in which the branch flow control member is constructed to define a second path configured to allow a part of the incoming main flow to flow from the entry to the exit without being branched off into the inner space and to branch off at least a part of the incoming main flow into the inner space via the supply channel, wherein in the first position the branch flow control member is constructed to branch off a larger part of the incoming main flow into the inner space via the supply channel than in the second position.
