Abstract
A nozzle resistance controlled by a piezoelectric element comprises a housing having a longitudinal bore, a piezoelectric element located in the longitudinal bore, a baffle plate supported by the piezoelectric element, a nozzle body located in the longitudinal bore such, that the bore extending through the nozzle body ends with one end adjacent to the baffle plate, and a chamber defined by the longitudinal bore and connected to the other end of the bore. The chamber is connected to a fluid supply device.
