Abstract

The blasting gun for compressed air, in which a dynamic effect of the air is utilized for removing dirt and for cleaning purposes, comprises a built-in oscillator seat valve for producing a pulsating air stream with periodically repeated pressure discharges at a frequency of the order of 2-50 Hz thus causing the valve alternately to open and close an air flow through the blasting gun, this oscillator seat valve comprising a longitudinally displaceable oblong valve body having an end for shutting off the air flow through an air outlet of the gun by resting in contact against a valve seat under the influence of a compression spring, the oblong valve body having another end embodied as a piston displaceable through a closed cylinder. The piston separates an inner volume of the cylinder into two complementary back and front portions, the back portion of the volume being connected to the air outlet which is located on an outer side of the valve seat via a longitudinal bore through the valve body, the front portion of the volume being connected to a pressurized air chamber located on an inner side of the valve seat via a duct.
