Document Type and Number:
WIPO Patent Application WO/2019/176679
Kind Code:
A1
Abstract:
Provided are: a solenoid that is capable of, when the amount of a current supplied to the solenoid is low, reducing a propelling force of the solenoid for biasing an object in one direction and capable of biasing the object in the same direction as that for the propelling force during non-energization of the solenoid; an electromagnetic valve; and a buffer. A solenoid (S) is provided with: a coil (40); a first movable iron core (45) and a second movable iron core (46) that are drawn in directions separating the two away from each other when current is passed through the coil (40); a coil spring (47) that biases the first movable iron core (45) toward the second movable iron core (46); and a plate spring (48) that restricts the first and second movable iron cores (45, 46) from approaching each other.
