ABSTRACT:
The pneumatic pulse generator comprises two cursors which are mobile internally of a chamber of a distributor body into which open an input of a pressurized gas, an output and a first conduit connected to a first compression chamber. A second conduit connects the output to a second compression chamber. Two choke devices enable the flow of pressurized gas to the two compression chambers to be regulated. The pulse generator enables a succession of square-wave pulses to be generated at the output, the pulses having a work period which is adjustable by means of one of the choke devices located on the second conduit and a pause period which is adjustable by means of one of the choke devices located on the first conduit. The generator is particularly useful for controlling a blower device for cleaning a dust filter.
