Device for cleaning a working surface of a printing machine

摘要

In a device for cleaning a working surface of a printing machine, in particular a rubber blanket washing device, having at least one nozzle strip (7), provided with spraying nozzles (8), and having at least one supply pump (15) for supplying cleaning liquid which can be fed to the nozzle strip (7) and can be ejected from the nozzle strip (7) with the aid of a pressure medium, preferably compressed air, a high reliability and universal applicability are guaranteed by the fact that a pressure increasing unit (9) which can be acted upon by cleaning liquid by means of the supply pump (15) and can be operated by the pressure medium is connected to the nozzle strip (7) by means of a high-pressure line (10), which pressure increasing unit has an accumulation space (19a) of an adjustable size, which can be filled with the cleaning liquid and can be closed relative to the high-pressure line (10) by means of a shut off member (31) which opens abruptly, and a working space (20a), which is larger relative to the accumulation space and can be acted upon by the pressure medium, for emptying the accumulation space (19a). <IMAGE>
