ABSTRACT:
This disclosure shows the supplying of fluid at a pressure greater than the pressure of the surrounding atmosphere to a cleaner in which the cleaning is done by intermittently and consecutively jetting fluid, controlled by a double distributing valve against the surface of the material being cleaned, where the total average pressure of the air or gas is maintained at a few inches of water below the pressure of the surrounding atmosphere. The double distributing valve, having circular outlets evenly spaced around a valve rotor, allows the same number of passages leading from the valve rotor cavity to jet nozzles to be in operation at all times and allows an increase in time for the jetting fluid through the jet nozzles to reach the desired speed.
