ABSTRACT:
In a piezo-control valve for fuel injection systems of internal combustion engines wherein a piezo-ceramic actuating rod is mounted with one end firmly to one end of a valve housing having a nozzle body with a valve seat disposed at the other end and a nozzle control needle is disposed in the nozzle body and pressed by the piezo-ceramic actuating rod onto the valve seat in the nozzle body when the piezo-ceramic actuating rod is not activated, the valve housing includes a sleeve-like portion disposed around the piezo-ceramic actuating rod which consists of a material compensating for temperature-caused changes in the length of the piezo-ceramic actuating rod.
