Jet regulator

A jet regulator (1, 10, 20) comprising a ring-shaped or sleeve-shaped jet regulator housing (2), an outlet face side (3) of which is formed as an outlet disk (8) which is inserted into the jet regulator housing (2) and which bears a perforated, grate or mesh structure with throughflow openings (6) bordered by flow-guiding walls, the perforated, grate or mesh structure on the outlet face side is produced at least in regions and at least on one surface thereof from a manually deformable dimensionally elastic plastic material (7), the outlet disk is inserted into the jet regulator housing (2) from an inlet-face-side ring or sleeve opening of the jet regulator housing (2) as far as at least one insertion stop (11), a jet splitter (14) which divides an inflowing water stream into a number of individual jets is positioned upstream of the outlet disk (8) as viewed in a flow direction, and at least one insert part (15, 16, 30, 19) which is inserted into the jet regulator housing (2) and has a perforated, grate or mesh structure with throughflow openings (19, 48, 43) bordered by flow-guiding walls is positioned upstream of the outlet disk (8), and/downstream of the jet splitter (14), as viewed in the flow direction, the outlet disk (8) is formed as a multi-component injection-molded part which has a main body (9) comprised of hard or dimensionally rigid plastic material onto which is injection-molded a constituent comprised of the dimensionally elastic plastic material (7) which is relatively softer than the dimensionally rigid plastic material, and the outlet disk (8) bears the constituent comprised of the relatively soft or dimensionally elastic plastic material (7) even in a partial region which bears against the jet regulator housing (2), so that the soft or dimensionally elastic plastic material (7) provides sealing in a ring-shaped zone between the outlet disk (8) and a housing inner circumference of the jet regulator housing (2).
