Patent ID: 7430996

Claim:
An electromagnetically driven valve that is operated by an electromagnetic force, comprising: a valve element which includes a valve shaft, and which is reciprocated in a direction in which the valve shaft extends; an oscillating member which extends from a driving end, that is moved in conjunction with the valve shaft, to a pivoting end, and which is oscillated around a central axis that extends at the pivoting end; a support member that supports the pivoting end of the oscillating member; and an electromagnet that is disposed so as to face the oscillating member, wherein the electromagnet includes a core made of magnetic material and having a central axis, and a coil wound in the core, and wherein a width of a flux path of the core at a pivoting end side is larger than a width of a flux path of the core at a driving end side, and the coil is offset to a driving end side with respect to the center axis.
