ABSTRACT:
A valve particularly adapted for use in obtaining a constant fluid flow output from a variable high pressure fluid input. The valve body includes a fluid passage extending therethrough having a valve seat intermediate the ends thereof. A fluid inlet communicates with the end of the passage on the upstream side of the seat and a fluid outlet communicates with the passage on the downstream side of the seat. An elongated actuating stem is closely received in the passage and includes a plurality of spaced radially extending fins disposed along a portion of its length. Each fin then includes a pair of oppositely disposed orifices to facilitate fluid flow therethrough and the fins are selectively positionable on the stem to provide variable flow characteristics through the valve. The rate of fluid flow through the valve may be easily regulated by adjusting the degree of insertion of the stem within the passage so as to yield the desired constant output flow rate.
