Patent number: 8931511Abstract: 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.Type: GrantFiled: March 5, 2013Date of Patent: January 13, 2015Assignee: Honda Motor Co., LtdInventors: Naoki Yajima, Tatsuhiro Tomari, Minoru Ueno

Patent number: 8925567Abstract: A thermal pressure relief device (TPRD) is shown and includes a housing having a first end with a first aperture and a second end having a second aperture. The first and second apertures are configured to allow a fluid to flow through the housing. The TPRD includes a trigger member, such as a ball, disposed within the housing. The ball is seated laterally within a retainer. The retainer includes a rim forming a seat for supporting the ball within the housing. The movement of the ball from the first closed position laterally seated within the retainer to the second open position descended within the retainer is caused by an expansion of the rim of the retainer. The rim of the retainer is formed substantially of a temperature sensitive material adapted to expand volumetrically with an increase in temperature. The temperature sensitive material can expand linearly or non-linearly.Type: GrantFiled: December 27, 2011Date of Patent: January 6, 2015Assignee: GM Global Technology Operations LLCInventor: Jörg Schulze
