Abstract: A device for washing inking elements of a rotary printing machine, particularly for washing the ink-transferring canvas cylinder, the ink recovery container, the doctor blade chamber and various conduits of the inking elements which are first washed by an arrangement for conducting a washing fluid through the conduits, comprises an arrangement mounted in a sub-frame having a distributor provided with nozzles, the distributor being mounted for pivotable movement and being shiftable transversely between the two sides of the sub-frames to provide a to-and-fro washing of the doctor blade chamber and recovery container. The angular position of the distributor is changed at the end of each stroke by the nozzles contacting a stop provided in the sub-frame and the transverse to-and-fro motion is preferably obtained by the distributor being connected to a piston of a linear pneumatic cylinder which is mounted in the subframe.
