An annular choke mechanism is incorporated into a flow path within the outer housing of the sleeve valve to the interior flow ports of the sliding sleeve member. As the sliding sleeve member is moved axially within the housing, the lateral fluid ports of the sliding sleeve member are aligned within particular bore portions so that the size of the annular space between the fluid ports in the housing and the fluid ports in the sleeve is varied. The annular flow area through the annular space governs the rate of fluid flow through the valve.
