1. A jet regulator (1) comprising:
an outlet structure (10) with an outlet mesh (11) having a regular arrangement (12) of holes (13) and a rim (16) that delimits the outlet mesh (11);
holes (17, 19, 25) of the outlet structure (10) adjacent to the rim (16) form a ring (18) and externally delimit a water jet flowing through the outlet structure (10);
the ring (18) is configured so as to deviate from the regular arrangement (12) in that at least one hole (17, 19, 25) of the ring (18), should an available opening cross section (21) thereof otherwise based on a continuation of the regular arrangement (12), be less than half a size of an available opening cross section (21) of an adjacent hole (23), is enlarged so as to deviate from the regular arrangement (12),
wherein at least one said hole (20) which lies in an interior (22) of the outlet structure (10) and is adjacent to one of the holes (17, 19, 25) of the ring (18) is curtailed by said hole (17, 19, 25) of the ring (18) such that the available opening cross section (21) of said at least one hole (20) is smaller than that of at least one of a largest or uncurtailed holes (13) of the regular arrangement (12).
