Abstract

See full text

A dishwasher with a height-adjustable upper rack carries a spray arm having a horizontal manifold tube that engages in a port of a check valve assembly coupled with a vertical main feed tube for supplying wash water to the spray arm. The check valve assembly defines a plurality of ports such that the manifold tube can engage a different one of the ports depending on the vertical position of the rack. The check valve assembly has flapper valves that pivot about horizontal axes and hang downwardly therefrom such that gravity tends to move the flapper valves toward their closed positions when the manifold tube is withdrawn from the ports.
