ABSTRACT:
A hydraulically limited fuel injection nozzle includes a lift control washer disposed about an elongated check valve stem so that the washer cooperates with a surrounding sleeve when acted upon by a pressure difference caused by fluid flow to control lift of the check valve. The arrangement moves the main flow restriction upstream of check valve.
