Abstract
An electromagnetically driven valve that operates by a combination of electromagnetic force and elastic force includes a valve element that has a valve shaft and that reciprocates in directions of extension of the valve shaft, and first and second oscillating members that extend from driving ends to pivoting ends, and that pivot about central axes extending at the pivoting ends. The driving ends are operatively linked with the valve element. An electromagnet oscillates the first and second oscillating members. First and second measuring portions measure at least one of the oscillation angle, the amount of lift and the oscillating speed of the first and second oscillating members. A control portion computes energization control logics based on measurement values provided by the first and second measuring portions, and averages the energization control logics to control energization of the electromagnet.
