End of injection rate shaping can be attained by controlling the flow rate into a check control cavity (34). Specifically, a flow control valve (30) allows the check control cavity (34) to vent at a first flow rate and to pressurize at a second slower flow rate. By pressurizing at a slower rate, end of injection does not occur as quickly, allowing injection pressure to decrease before injection is terminated. <IMAGE>
