Abstract: A hydraulic control system employing pressure differentials for control functions will maintain uniform pressure differentials over a broad temperature range by incorporation of the thermal compensator valve connected in parallel with the pressure differential generating device so the fluid flow through the device is controlled as a function of temperature to maintain a constant output from a device for a given set of physical conditions. The valve itself includes an inlet and an outlet with a flow-control spool disposed in a passage therebetween to meter the fluid and a thermal responsive element connected to position the spool in response to fluid temperature whereby the output of the device will remain essentially constant for a given physical set of conditions regardless of the temperature of the fluid.
