Patent number: 11940057Abstract: A valve device includes a flow path formation member provided with at least one flow path hole through which a fluid passes, and a drive part that outputs a rotational force. The valve device includes a shaft, and a rotor having a sliding surface that slides while facing an opening surface of the flow path formation member where the flow path hole is opened, and the rotor is configured to increase or decrease an opening degree of the flow path hole with rotation of the shaft. The valve device includes an energization member that energizes the rotor toward the flow path formation member. The valve device includes a coupling structure configured to tiltably couple the shaft to the rotor such that a contact state between the sliding surface and the opening surface is held regardless of a posture or a position of the shaft.Type: GrantFiled: March 1, 2022Date of Patent: March 26, 2024Assignee: DENSO CORPORATIONInventors: Syota Kimura, Hiroki Shimada, Akira Higuchi, Takehito Mizunuma, Takuya Hamada, Ryou Sano

Publication number: 20170335836Abstract: Provided is a novel electroosmotic pump capable of being driven by AC voltage. An electroosmotic pump (2) includes a porous dielectric membrane (21), a first water-permeable electrode (22), and a second water-permeable electrode (23). The first water-permeable electrode (22) is disposed on one side of the porous dielectric membrane (21). The second water-permeable electrode (23) is disposed on the other side of the porous dielectric membrane (21). A principal surface of the porous dielectric membrane (21) close to the first water-permeable electrode (22) and a principal surface thereof close to the second water-permeable electrode (23) have mutually different hydrophilicities.Type: ApplicationFiled: July 20, 2017Publication date: November 23, 2017Applicants: SEKISUI CHEMICAL CO., LTD., KYUSHU UNIVERSITY, NATIONAL UNIVERSITY CORPORATIONInventors: Yasushi OKUMURA, Hirotsugu KIKUCHI, Hiroki HIGUCHI, Manabu TANIGUCHI, Kazuki YAMAMOTO
