Abstract
The present invention relates to a method and a device for cleaning objects, preferably spray guns. At least one pulse counting device (9) is provided to count the number of pulses of the pulsating flow of washing liquid in a washing-liquid conduit (7) which feeds the washing liquid (3) from a washing-liquid pump (5) to at least one washing-liquid nozzle (2). The pulse counting device (9) controls at least one valve device (11) to close, in dependence of a predetermined number of pulses counted by the pulse counting device (9), a pressure-medium conduit (13) to the washing-liquid pump (5) so that the operation thereof is interrupted. Hereby, it is ensured that the desired and actual amounts or volumes of washing liquid are the same during each washing process.
