Jet regulator

The invention relates to a jet regulator, comprising a jet regulator housing, within the interior of which a jet regulation device is provided. According to the invention, such a jet regulator can be produced at low cost, by means of simple conventional production techniques with simultaneous anti-scaling effect on the jet regulation device, whereby the jet regulation device comprises several insertable components, which may be inserted in series in the jet regulator housing in the direction of flow (Pf). The insertable components comprise passage openings, which are unidirectionally defined and extend across the cross-section of the passage, and the passage openings of adjacent insertable components are arranged offset to each other in the circumferential direction of the jet regulator housing, or in the direction of flow (Pf) of the jet regulator.
