permanently held in contact with plate shaped connecting element 28 therefore the expansion of piezoelectric actuator 12 causes valve closing body 2 to lift and fuel injection valve 1 to thereby open it is essential that the elastic force of spring 29 be greater than the elastic force of pulling spring 45 when the electrical excitation voltage is turned off piezoelectric actuator 12 contracts again so that spring 29 again brings valve closing body 2 in contact with valve seat body 4 via plate shaped connecting element 28 equalizing sleeve 23 and valve needle 3 and thus closes fuel injection valve 1 since equalizing sleeve 23 has the same axial length as piezoelectric actuator 12 and both piezoelectric actuator 12 and equalizing sleeve 23 have an extremely low temperature expansion coefficient valve lift is almost temperature independent in particular the area of valve housing 7 surrounding piezoelectric actuator 12 and equalizing sleeve 23 have no influence on the valve lift since its thermal expansion is compensated by spring 29 a conducting compound can be applied between actuator 12 and equalizing sleeve 23 either in the exemplary embodiment of fig1 or in the exemplary embodiment of fig4 for improved heat capacity between equalizing sleeve 23 and actuator 12 instead of pulling spring 45 the flush contact between flange 11 of valve needle 3 with first end 24 of equalizing sleeve 23 and the flush contact with second end 26 of equalizing sleeve 23 with plate shaped connecting element 28 can also be implemented by gluing or pressing for example since fuel flows through the center of fuel injection valve 1 according to the exemplary embodiment illustrated in fig4.
