A flow regulator for high-pressure fluids at elevated temperatures includes a body having a flow passage extending between inlet and outlet openings. First and second orifice members are arranged in the flow passage so at least one of the orifice members can be moved transversely in relation to the flow passage between one operating position where the two orifice openings are aligned for establishing a maximum flow rate of fluids flowing through the flow passage and at least one other operating position in which the two openings are moderately misaligned with one another for establishing a predetermined reduced flow rate of fluids flowing through the flow passage.

Apparatus for regulating the flow of fluids comprising: a body including inlet and outlet flow passages on opposite sides of an intermediate central portion; a first fixed orifice member arranged in said inlet flow passage and a transversely movable second orifice member in said central portion, said orifice members having juxtaposed adjacent ends which are shaped for cooperatively defining complemental transverse surfaces as well as first and second longitudinal orifice passages extending between the opposite ends of said orifice members and terminating in first and second reduced throat portions which are respectively circumscribed by said complemental end surfaces and aligned with the longitudinal axis of the fixed orifice in a first flow position; means for maintaining at least those portions of said complemental end surfaces surrounding said throat portions of said orifice passages in contact with each other as said second orifice member is being moved transversely in relation to said first orifice member; and actuating means cooperatively arranged on said body for selectively moving said second orifice member transversely in relation to said first orifice member only between a first flow-regulating position where said throat portions are in alignment with one another for establishing the first flow rate for fluids flowing through said flow passage and a second flow-regulating position where said throat portions are only partially misaligned in relation to one another to establish a reduced second flow rate for fluids flowing through said flow passage.
