摘要

A diffusor intended for the throughpassage of a fluid comprises a plate having a multitude of channels which extend therethrough in a mutually parallel relationship. The channels are closed at one of their ends and are connected to a connecting member at the other one of their ends. The plate is provided on one side thereof with a permeable wall for the throughpassage of the fluid.
