Abstract : A resistive element for a fluidic system having a load and a supply of working fluid at a supply pressure which is a constant independent of temperature. The resistive element comprises a housing, of a relatively low temperature coefficient of expansion material such as a steel, enclosing a pair of coplanar plates of predetermined dimensions and fabricated from a relatively high temperature coefficient of expansion material, such as a magnesium alloy. The adjacent walls of the plates define the sidewalls of a channel for fluid flow. The plates are slidably mounted inside the housing so as to vary the width of the rectangular channel at a constant rate in response to incremental variations in the fluid temperature. The constant variation in channel width keeps the Reynolds number of the fluid passing through the channel at a substantially constant value despite small increments in the fluid temperature about its operating temperature.
