Abstract
There is disclosed an automatic firing system for pneumatic tools wherein there is a remote valve to produce actuation of the main valve of the device which remote valve has only one moving part, combined with a selector valve, by means of which the tool may be converted from single fire to auto-fire modes, and in the auto-fire mode the rate of fire may be controlled. The pneumatic circuitry is such that less compressed air is used than in conventional auto-fire tools and thus the tool is more economical than prior art tools.
