A coil resistance change reduction type solenoid valve is provided to have enough valve magnetic force by preventing coil resistance from being changed due to temperature rise in operation of a solenoid valve. A coil resistance change reduction type solenoid valve comprises: an armature(1) excited through provided current; a valve body(2) including a filter(3) removing impurity inside oil; a coil case(7) covering a bobbin(5); a gap(A) formed in the top of the bobbin; and a coil assembly(4) in which the bottom side of the bobbin is contacted to a pump housing(PH). The valve body is overlapped in order to be connected in a flow channel of the pump housing. |
