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.

L'invention porte sur un procédé et un dispositif de nettoyage d'objets de préférence à l'aide de pistolets utilisant au moins un dispositif (9) de comptage du nombre d'impulsions du flux pulsé du liquide de lavage circulant dans une conduite (7) transportant ledit liquide (3) depuis sa pompe (5) de mise en pression jusqu'à une ou plusieurs buses (2) de projection. Le dispositif (9) de comptage commande au moins une soupape (11), qui ferme un conduit (13) alimentant la pompe (5) en fluide sous pression, après un nombre prédéterminé d'impulsions comptées par le dispositif (9) de comptage, et en interrompt le fonctionnement. On s'assure de ce fait que les quantités ou volumes désirés sont effectivement les mêmes pour chaque lavage.
