Abstract
The present invention relates to a method and a device for cleaning objects, preferably spray guns. At least one pulse counting device ( ) is provided to count the number of pulses of the pulsating flow of washing liquid in a washing-liquid conduit ( ) which feeds the washing liquid ( ) from a washing-liquid pump ( ) to at least one washing-liquid nozzle ( ). The pulse counting device ( ) controls at least one valve device ( ) to close, in dependence of a predetermined number of pulses counted by the pulse counting device ( ), a pressure-medium conduit ( ) to the washing-liquid pump ( ) 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.
