Method for cleaning a spray gun

A recovery device ( ) includes a container ( ) for recovering pure solvent ( ) A measuring device ( ) includes a capacitive detector ( ) which is provided to signal if the container ( ) is not empty nor substantially empty when one tries to start operation of the recovering pure solvent ( ).

Measuring device

The present invention relates to a device at washing apparatus for washing objects, preferably spray guns, with a washing liquid, preferably a solvent. The washing apparatus ( or A) has at least one wash chamber ( ) in which the object ( ) is located for washing and at least one first container (B ) for collecting impure washing liquid from the wash chamber ( ). The washing apparatus ( or A) further comprises a distilling device ( ) for distillation of impure washing liquid and obtaining pure washing liquid. This distilling device ( ) includes a third container (B ) in which impure washing liquid is vaporized. Means are provided to see to that the volume (V ) of impure washing liquid which at the most or as a maximum can be brought to flow from said first container (B ) to said third container (B ) is equal to or less than the volume (V ) for washing liquid in said third container (B ) in order to prevent said third container (B ) from located overfull (FIG. ).
