A flow limiter (110) has an inner housing (3) with a cylindrical recess (4), an annular throttle body (5) installed therein, and a control wedge (6). On the outer side of the control wedge (6) and/or the inner side of the housing (3), expanding in the flow direction, steps (terraces) (18) of annular step shape are provided. By this means, a reduction in the level of noise is achieved (Fig. 1). <IMAGE>
