    • An aerator for introducing air into a liquid flowing under pressure through a spout, the aerator being partially or totally concealed by the spout and being substitutable-in dimensions and flow characteristics-with a conventional, unconcealed aerator having standard male threading. The concealed aerator is couplable to a spout having female threading at the most downstream portion thereof and provides enhanced sealing between the concealed aerator and spout. Specifically, for a concealed aerator including two concentric tubular members with an air space therebetween, the present invention teaches the forming of a seal between the upstream surfaces of both tubular members against an annular shelf defined within the spout.
    • 一种用于将空气引入通过喷口在压力下流动的液体的曝气器,曝气器由喷口部分或完全隐藏并且可在尺寸和流动特性中被替代 - 与具有标准公螺纹的常规的未隐藏的曝气器。 隐藏的曝气器可连接到在其最下游部分处具有阴螺纹的喷嘴,并且在隐藏的曝气器和喷口之间提供增强的密封。 具体来说,对于包括两个具有空气间隔的同心管状构件的隐蔽曝气器,本发明教导了两个管状构件的上游表面之间的密封件与限定在喷嘴内的环形搁架形成密封。
