Abstract: Apparatus for selectively coupling a source of pressurized fluid to washing machine containers which hold items during wash cycles where there are first containers adapted for preventing the flow of fluid and second containers adapted for receiving the fluid when the containers are placed in their normal positions in the washing machine. The apparatus includes a member having a contoured passage therethrough and which defines an inlet and an outlet and means slidably disposed within the member for controlling the flow of fluid through the outlet to the containers. The flow control means has a first portion, which may include a body and a flange and a second portion which may be an elongate pin. The first portion is adapted for such engagement with the contours of the passage that the flow control means can assume a first position for preventing the flow and a second position for permitting the flow.
