Patent number: 11035493Abstract: Provided is a small-sized controller capable of precisely controlling a flow rate of a high-pressure fluid. Between a working shaft of a drive device and a valve stem, a power transmission device is disposed to amplify a force acting on the working shaft and transmit the resultant force to the valve stem. A diaphragm as a valve element is made of metal and is deformable to: a state where a fluid passage is fully closed; a state where the fluid passage is fully open; or a state where the fluid passage is partially open. When the fluid passage is partially open, on the basis of the flow rate of a fluid flowing through fluid passages, the drive device finely adjusts the position of the working shaft such that the flow rate is constant.Type: GrantFiled: March 27, 2018Date of Patent: June 15, 2021Assignee: FUJIKIN INCORPORATEDInventors: Keisuke Ishibashi, Michio Yamaji, Tadayuki Yakushijin, Shunji Obara, Keigo Kobayashi
