'An aerator has a pressure responsive valve assembly therein for restricting the flow therethrough when the pressure of the water supply is increased. The aerator includes a housing mounting a stream straightener member and a partition member. The partition member seats an annular O-ring which in turn seats a movable valve element. The valve element and partition define an assembly with a variable sized passageway. The valve element is responsive to pressure from the pressure source to compress and move the O-ring to constringe the passageway. A mixing body is movably mounted between the stream straightener and the partition member for mixing water from the passageway with air. The valve element has a depending leg which is manually operable from the outlet of the housing. The leg can be pressed upwardly to lift the valve element which opens up the passageway thereby creating turbulence in the aerator. The turbulence vibrates the mixing body which can be audibly detected to indicate that the aerator is being flushed and cleaned.

An aerator device characterized by: a housing having an inlet and outlet; seat means in said housing for seating a movable valve element and having a passage for allowing fluid to pass by said valve element; said valve element including a downwardly depending leg; said leg extending downstream and having a downstream end being engageable from said outlet whereby upon a manually exerted upward force, said leg lifts said valve element upward against the pressure of a fluid supply to provide for increased flow by said valve element; air passage means for introducing air into said fluid flowing by said valve element; a mixing body being slidably mounted for axial movement along said leg below said seat means such that fluid passes through said passage and mixes with said air upon impinging on said mixing body when said valve element is in a normal position and vibrates up and down on said leg to produce an audible noise when said leg and valve element are in a raised position and said increased flow occurs.
