PCT No. PCT/JP97/02944 Sec. 371 Date Jan. 27, 2000 Sec. 102(e) Date Jan. 27, 2000 PCT Filed Aug. 25, 1997 PCT Pub. No. WO99/10670 PCT Pub. Date Mar. 4, 1999The present invention provides a compact duty-driven solenoid valve which inhibits occurrence of impact sound upon driving and prevents occurrence of adherence at low temperatures. In this duty-driven solenoid valve, a plunger is arranged in a center hole of a bobbin having a coil wound thereon, and a guide made of a magnetic material is arranged on one end side of the bobbin, opposite to the plunger. A spring is provided so as to impart a force to move the plunger toward the guide, and further, a valve assembly for switching over a channel for a control fluid is arranged opposite to the plunger with the guide in between. A rod for transmitting a moving force of the plunger to the valve assembly is arranged so as to be inserted through the guide and to reach the valve assembly. The positional relationship between the rod and the valve assembly is configured to maintain a prescribed gap between the plunger and the guide during feeding of current to the coil.
