Abstract (en)
[origin: WO9218260A1] The dusting gun is of the type used for removal of dirt and for cleaning purposes, for example cleaning of agricultural implements, motor car undercarriages before treatment of the undercarriage and similar jobs where dirt, dust, oil and other loose or firmly sticking coats are removed with compressed air. The dusting gun is peculiar in that it is equipped with an oscillating pressure discharge valve, which causes a splitting up of the air flow into periodically repeated pressure discharges. The oscillation valve acts automatically under the influence of the static and dynamic pressures of the passing air flow. In practice the pulsating air flow has proved to have markedly better cleaning properties in comparison with the usual dusting guns from which the air is given off in a continuous jet. Especially in the case of firmly sticking impurities does the pulsating air jet have a distinct loosening effect. The splitting up of the air flow into separate pressure discharges (pulses) causes a saving in the consumption of compressed air.
