1. A jet regulator (1) for producing an aerated liquid jet, the jet regulator comprising:
a housing (2),
a jet accelerator device (3) for producing at least one accelerated jet located in the housing,
a jet aeration device (5) which is arranged after the jet accelerator device (3) in a flow direction (4) and which serves for mixing liquid portions with air, the jet aeration device (5) has a chamber (6) with at least one aeration opening (7) through which air can be sucked into the chamber (6), and
an aperture plate (8) arranged within the chamber (6) and which divides the chamber (6) into an air inlet part (9) and a mixing part (10),
wherein the mixing part (10) and the air inlet part (9) are connected to one another via an aperture plate opening (11) of the aperture plate (8),
wherein a side wall (17) of the mixing part (10) is oriented non-parallel to a longitudinal axis (12) of the housing (2),
wherein an impingement body (26) is arranged in the mixing part (10) and at least partially projects into the air inlet part (9),
wherein the impingement body (26) has a conical form, and
wherein the impingement body (26) has an impingement surface on which multiple impingement elements (27) are arranged, each of the multiple impingement elements (27) being pegs and projecting from the impingement surface of the impingement body (26) in a direction opposite the flow direction (4).
