20120193560 | VALVE DEVICE - A valve device includes an oil path that is formed such that a hydraulic fluid flows therethrough, a ball valve that opens and closes the oil path, and a contraction-type PVC gel actuator including a plurality of planar cathode plates, a plurality of mesh-like anode plates, and PVC gel layers. The cathode plates and the anode plates are alternately stacked one on top of the other with the PVC gel layers sandwiched therebetween. With expansion or contraction deformation of the contraction-type PVC gel actuator, the ball valve is driven so as to close or open the oil path. The cathode plates and the anode plates included in the contraction-type PVC gel actuator are interconnected using the belt-like wiring portions. Thus, an integrated unit of the plurality of cathode plates and an integrated unit of the plurality of anode plates are formed. | 08-02-2012 |
20130233415 | VALVE DEVICE AND FAILURE DETECTOR OF HYDRAULIC CIRCUIT - 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. | 09-12-2013 |
