Abstract

PURPOSE:To prevent pulsation, omit an air chamber and reduce rise time by journabling a pressurizing member integrally in an ink pressurizing chamber with a rotor rotated by a stator arranged outside the ink pressurizing chamber. CONSTITUTION:By rotating a spiral disc 24 with a rotor 21 by a stator 22 ink of a definite pressure is supplied to a jet nozzle opening a check valve 28. If the pressure in an ink pressurizing chamber 20 reaches a preset pressure, the rotation of the rotor 21 is stopped by the ink pressure. If an electromagnetic valve is opened, ink supply to the jet nozzle is started and the rotor 21 is rotated slowly to pressurize the quantity of the jetted ink with the disc 24 and ink of a definite pressure is supplied to the jet nozzle.
