摘要： Several embodiments are disclosed of various spool configurations for controlling the flow of an expandable fluid from a high pressure zone to a zone of lesser pressure. The spools structurally conform to a novel principle of controlling the expansion of the fluid from a point of initial throttling throughout the entire expansion profile provided by the valve in such a way that overexpansion of the fluid at any given point is substantially reduced or entirely eliminated.
