Abstract
A valve device is provided with a contraction-type high polymer gel actuator which laminates slab-like negative plates and mesh-like positive plates alternately and interleaves high polymer gel between each negative plate and each positive plate, and with a first and a second valve mechanisms driven by the gel actuator. The direction of deformation of expansion and contraction of the high polymer gel actuator is the same as the driving direction of the first valve mechanism and perpendicular to the driving direction of the second valve mechanism. The valve device is composed in such a way as to switch opening and closing of a first fluid passage and a second fluid passage simultaneously by means of deformation of expansion and contraction by controlling voltage applied to the high polymer gel actuator. This allows to compose a valve device that can open and close plural oil passages at an identical timing.
