ABSTRACT:
An electromagnetically driven valve includes a valve element, a main body, a disc, and a lower electromagnetic. The valve element includes a valve stem, and is reciprocated in the direction in which the valve stem extends. The main body is provided at a position distant from the valve element. The disc includes a driving end that is moved in conjunction with the valve stem, and a pivoting end that is supported by the main body such that the pivoting end can be oscillated. The disc is oscillated around a central axis that extends at the pivoting end. The lower electromagnet is disposed so as to face the disc. The lower electromagnetic includes a core made of magnetic material, and a coil wound in the core. The coil is offset to a driving end side with respect to a central of the core.
