ABSTRACT:
Disclosed is a water-supply valve of a washing machine in which the consumption of electric power can be minimized in opening and closing the valve to supply water into and block off the water supply from a washing tub of the washing machine. In the water-supply valve, an actuator rod is elevated against downward biasing force of a spring by a magnetic force of the solenoid generated by applying a voltage thereto, and then is retained at its uppermost position by the engagement between protuberances protruded from the inner wall of the actuator chamber and circumferential strips formed on the actuator rod.
