ABSTRACT:
A manually operated blow gun for cleaning work pieces by use of compressed air which includes a back pressure sensitive control that is effective when the gun is dead ended with the trigger depressed. The gun has a trigger operated valve which causes actuation of a main output valve, wherein when back pressure is increased, the pressure is directed via a by-pass conduit to close the main output valve against the action of the trigger operated valve.
