Gerni A/s

Gert Nielsen

An apparatus for cleaning objects by means of a jet of liquid and comprising an upright pressure tank with a liquid filling pipe extending downwards therein for filling the tank to a predetermined level. The air cushion above the liquid surface is pressurized through valve means at the top of the tank, and the liquid can be forced through a connecting branch to a hose provided with a spray gun. This connecting branch opens on to the tank at a level above the heating means in the liquid. Pressure relief means are provided so that the upper space of the tank is ventilated to the atmosphere before a closing member at the top of the filling pipe is fully opened, so that hot liquid and possibly the closure member itself cannot be ejected by the pressurized tank. Furthermore a safety device arranged between the pressure tank and the spray gun hose ensures that only a limited amount of liquid will flow through if the liquid pressure in the hose falls owing to rupture of the hose wall.
