Abstract

The pulsed gas supply consists of a cylindrical gas reservoir which conta a multiplicity of small release ports in a helical pattern and an inner cylindrical rotary valve which also contains a multiplicity of small release ports in the same helical pattern. The reservoir and valve constitute an integral unit which has the advantage of totally balanced forces on a single moving part. This allows for motion free of friction caused by the high pressures of the gas supply.
