摘要：
In a proportional solenoid valve, a valve drive portion that includes a coil, a core that is excited by application of a current to the coil, a plunger that is displaced by a magnetic attraction force generated by the excited core, and a spring that biases the plunger in a direction in which a distance to the core is increased. The spring is set so that a space is maintained between the plunger and an attraction surface of the core when the spring is fully compressed.
