PURPOSE: An instantaneous electric current application type electric valve is provided to avoid the discharge of a battery and to improve the durability of an electric valve by instantaneously applying electric currents to the valve via an electric motor. CONSTITUTION: A transmission section(3) and a non-transmission section(4) are formed on the outer face of a body having a rotating switch(1). Pistons(8) are installed in a first valve and a second valve. The pistons are operated by a motor(7). A clamp(10) is installed on a rotating shaft(9) of the piston to restrain the rotation over 90 angular degrees of the piston. According to the transmission section and the non-transmission section, the rotational direction of the piston is controlled. If the rotating switch is placed in the non-transmission section, electric currents are blocked up.
