摘要： A valve assembly for controlling the rate of flow of fluid between a valve inlet and a valve outlet comprises a valve housing, and a spool valve member that is movable axially within a valve bore provided in the valve housing in an opening direction and a closing direction. The spool valve member is provided with a blind bore, the open end of which communicates with the valve outlet, and at least one opening into the blind bore, the at least one opening communicating, to a variable degree dependent on the axial position of the spool valve member within the valve bore, with the valve inlet. The valve inlet comprises a first boundary and a second boundary, so that for axial positions of the spool valve member in which the opening does not overlap the first boundary there is no flow into the outlet.
