Abstract

A solenoid driven valve is disclosed which is adaptable for controlling the introduction of a high pressure fluid into a fluid trapping assembly having an absorption column topped with an annular orifice expansion nozzle. The valve has an inlet port to introduce high pressure fluid, an axially moving solenoid driven pin which engages means to restrict fluid flow into said column. A diaphragm is located within the valve to direct fluid into the column and which separates the fluid in a region of high pressure from ambient pressures.
