PURPOSE: A noiselessness solenoid valve is provided to reduce the metallic noise generated by crashing between the lower part of a tube top and the upper part of a plunger. CONSTITUTION: A noiselessness solenoid valve comprises a valve body, a bobbin, a housing(90), a tube top and a plunger. The valve body is combined in one side of a stream tube. The bobbin is combined in the inside of the valve body. A solenoid coil in which the power is applied from outside is wound in the outer circumference of the bobbin. The housing, a hollow shaped tube is combined in the guide groove of the bobbin. One end of the tube top is connected through one end of the valve body. The plunger ascends and descends along a sliding groove.
