Flow control valve and blood pressure information measurement device having the same

Abstract

A flow control valve includes a bobbin around which a solenoid coil is wound, a plunger inserted into the bobbin so as to be capable of sliding, a core in which is provided an outflow port from which a fluid flows, a spring that biases the plunger in a direction away from the core, and a valve body incorporated into the plunger so as to be disposed facing the outflow port. During a non-operating state, the valve body is disposed at a first position distanced from the outflow port. During an operating state, the plunger is pulled toward the core against a biasing force of the spring, and is not in contact with the core when the valve body is at a second position in which the valve body blocks the outflow port.
