Patent ID: 8141842

Claim:
A solenoid valve comprising: a valve housing in which a spool valve element is fitted so as to be reciprocably slidable along an axis; a magnet coil that moves the spool valve element in a first direction along the axis by an action of an electromagnetic force; a return spring that biases the spool valve element in a second direction, which is opposite to the first direction, and moves the spool valve element in the second direction when the magnet coil is not excited; and first and second attraction members that are respectively fixed to an end portion on the first direction side of the spool valve element and the valve housing such that the first and the second attraction members are spaced apart from each other along the axis by a distance equal to or greater than a maximum moving amount of the spool valve element and magnetically attract each other by a magnetic attraction force smaller than a bias force of the return spring when the magnet coil is not excited.
