The machine has a central section (100) supporting a bank of washing nozzles and one or two side extensions (201, 202) which are connected to the central section and can be opened or closed by a motor (V1, V2). The side and central sections are joined by a connection (310, 320) with an integrated valve which is simultaneously operated by the motor when the side extensions are opened or closed. The connection (310) consists of a hollow, fixed body (311) with a opening (312) supplying the washing fluid which connects with the central section (100). It has a moving section (313) attached to the side extension (201) which turns within the fixed body (311). There is a radial hole (314) which connects with the side extension (201). The moving section (313) turns simultaneously with the side extension so that the radial hole (314) is lined up with the supply opening (312) in the open position allowing the washing fluid to flow to the extension. The two holes are not aligned when the extension is closed.
