Abstract (en)
[origin: US7824015B2] An ink jet writing head includes a pressurized ink chamber provide with at least one ink nozzle that is closed by a mobile valve body. A piezoelectric valve actuating device that is electrically connected to a control device drives the valve body with reciprocating motions. The valve body is held by a closing spring in the closing position thereof and is connected to a connecting rod in a driving manner. At least one curved spring strip engages with the end of the connecting rod, located at a distance from the valve, the spring strip being supported on the valve-side end thereof, opposite the ink chamber. The connecting rod is subjected to the tractional prestress of a tension spring. At least one piezoelctric element is applied to the spring strip, the piezoelectric element being controlled by the control device in such a way as to perform tractile movements.
