Patent number: 10767785Abstract: A pneumatically-actuated valve is provided in which a spring member that applies an axial force to a shaft connected to a valve body, in an axial direction of the shaft, and a valve-actuating pressure chamber that actuates the valve body by applying a force resisting the axial force to the shaft are provided inside a valve casing. The pneumatically-actuated valve includes an axial-force adjusting device that adjusts the magnitude of energy stored in the spring member, via a surface-pressure adjusting screw provided to be inserted through the valve casing, from the outside of the valve casing.Type: GrantFiled: October 17, 2016Date of Patent: September 8, 2020Assignee: IHI CorporationInventors: Kohei Taya, Hatsuo Mori, Tomoharu Oda, Masanori Suzuki

Patent number: 10527189Abstract: A valve actuator is a valve actuator that drives opening and closing of a poppet valve and includes a motor and a transmission mechanism that transmits a drive force of the motor to the poppet valve. The transmission mechanism includes a booster mechanism. The booster mechanism is a three-dimensional toggle mechanism that includes a cylinder, an input disc that rotates about an axis in the cylinder, an output disc that reciprocates along an axial direction in the cylinder, and a link that connects the input disc and the output disc.Type: GrantFiled: April 30, 2018Date of Patent: January 7, 2020Assignee: IHI CorporationInventors: Kohei Taya, Hatsuo Mori, Kenji Hirai, Yu Hirata, Masahiro Tanaka, Takeshi Takaki

Patent number: 10145481Abstract: Provided is a pneumatic valve in which a seal member; a shaft provided with a valve body capable of abutting against the seal member; and a valve-actuating pressure chamber that moves the shaft in an axial direction to actuate the valve body is provided within a valve casing. The shaft has a first member that receives pressure from the valve-actuating pressure chamber, and a second member that includes the valve body and is movable relative to the first member in the axial direction. The pneumatic valve further has a stopper that is provided in a movement path of the first member, and a disc spring that is sandwiched between the first member and the second member, has elastic energy accumulated therein in a state where the first member is in contact with the stopper, and presses the valve body against the seal member.Type: GrantFiled: December 2, 2016Date of Patent: December 4, 2018Assignee: IHI CorporationInventors: Kohei Taya, Hatsuo Mori

Patent number: 10072611Abstract: A gas generator includes an injector that injects a fuel and an oxidizer, and a combustor that mixes and burns the fuel and the oxidizer injected from the injector. The injector includes a plurality of injection elements arranged on a face plate. Each of the injection elements includes unlike-impingement type injection nozzles that inject the fuel and the oxidizer toward a combustion point in front of the face plate, and injection nozzles that inject fuel for dilution to a dilution point DP forward further than the combustion point.Type: GrantFiled: February 8, 2016Date of Patent: September 11, 2018Assignee: IHI CorporationInventors: Kohei Taya, Yasuhiro Ishikawa
