A fuel injection device (10) is used in internal combustion engines (94). It includes a housing (12) with an injection end (18). A recess (20) extends in the housing (12). An axially movable valve element (24) is disposed in the recess (20); it cooperates with a valve seat and has a pressure face (36), remote from the injection end (18), which axially defines a control chamber (38). A sleeve part (40) is also provided, which radially defines the control chamber (38). A device (55) puts the sleeve part (40) against a first housing portion (16) and the valve element (24) in the direction of the injection end (18) with prestressing. To improve the precision in operation of the fuel injection device (10), it is proposed that the device (55) include separate prestressing devices (46, 50); one prestressing device (50) acts upon the valve element (24), and another prestressing device (46) acts upon the sleeve part (40).
