Aerator (102) which is substantially or entirely concealed within a spout (100) or the like. Liquid flowing through the spout (100) has air introduced into the flow by the aerator (102). The aerator (102) includes a tubular element (110) in which is contained a screen (108) and to which a jet forming element (104) is integrally coupled. Liquid flows through the jet forming element (104) which has a first flow cross-section and thereafter through the screen (108) which has a larger flow cross-section. The downstream portion (132) of the tubular element (110) terminates at a mouth (118). The screen (108) is recessed or recessable upstream from the mouth (118) enough to permit a coin (122) or the like to be inserted into indentations (124, 126) and twisted for easy aerator installation and removal. The jet forming element (104) and tubular element (110) are preferably molded into a unitary, plastic structure. |
