PURPOSE: A pressure and flow rate adjusting device using lorentz force is provided to automatically adjust pressure and a flow rate with set voltage by adjusting the size of a nozzle hole using magnetic force between a natural magnet and an electromagnet and to regularly keep the pressure and flow rate regardless of pressure of a pressure port by automatically controlling all adjustments through an instrument board. CONSTITUTION: A body(4) of a pressure and flow rate adjusting device contains a pressure port(1) flowing vapor or liquid inside. A natural magnet(2) and a metal(3) are stuck together and two electronic coils(5) are formed in the lower portion of the body. When voltage is supplied through a voltage supply line(6), the electronic coils change the metal to an electromagnet(3). Further, the body contains an exit(7) discharging vapor or liquid. Since the natural magnet and the electromagnet are pushed each other with magnetic force, the hole size of a nozzle(8) is adjusted depending on the pushing force. Thus, the pressure and the flow rate of the vapor or the liquid are automatically adjusted and kept in regular regardless of the pressure of the pressure port.
