1. In a trapping assembly for use with fluid systems having a column for removing a solute component of said fluid, the combination comprising:
- inlet means for introducing said fluid under pressure into assembly,axially driven valve means for controlling the fluid flow through said inlet means, andan annular orifice expansion nozzle leading from said valve means to said column, wherein said valve means is driven and includes an axially moving pin adapted to restrict the flow of said fluid through said valve means by closing said orifice expansion nozzle.

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.

7. In a trapping assembly for use with high-pressure fluid systems having a column for removing a solute component of said fluid, said assembly comprising:
-
inlet means for introducing said fluid under high pressure into said assembly, axially driven valve means for controlling the fluid through said inlet means, an annular orifice expansion nozzle with a conical diverging section leading from said valve means directly into said column, said valve means comprising;
an axially-moving, solenoid-driven pin, a diaphragm for directing the flow of said fluid from said inlet means into said column, and a valve seat, said valve seat located at the narrow end of said orifice expansion nozzle, and axial movement of said pin being adapted to restrict the flow through and to close said orifice expansion nozzle. - View Dependent Claims (8, 9, 10, 11, 12, 13)
