Abstract
A temperature-compensated fluid flow control valve for a valve system of an automatic transmission having a displaceable valve spool which is acted upon by pressure in a valve chamber against the force of a spring and on which an additional force proportional to temperature counteracts the pressure loading, the additional force being produced by the back pressure at an outflow orifice of variable cross-section which is reduced in size as the temperature rises.
