Patent number: 9410635Abstract: A fuel vapor control device has a flow control valve which regulates a flow amount of fuel vapor from a fuel tank to a canister. The flow control valve has a movable element accommodated in a case. The movable valve element has a central cylindrical part, an outer cylindrical part, and a disc part which connects the central cylindrical part and the outer cylindrical part. The central cylindrical part provides a central channel. The central channel provides a main channel which communicates an inlet and an outlet. A sub channel defined and formed between the movable element and the case is opened and closed by a valve formed by the case and the outer cylindrical part. The central channel makes easy setting of flow amount in regulated condition. Since turbulence is reduced, it is possible to perform stable regulation.Type: GrantFiled: April 2, 2015Date of Patent: August 9, 2016Assignee: Kyosan Denki Co., Ltd.Inventors: Yasuo Akimoto, Nobuharu Muto

Patent number: 9360219Abstract: A system includes a turbine engine with a fueling system including a valve fluidly coupled to a fuel supply on an upstream side and fluidly coupled to fueling passages on a downstream side. The valve maintains the fuel supply at a pressure greater than an ambient pressure. The system includes nozzle exits corresponding to the fueling passages, and the fueling passages flow fuel from the valve to each of the nozzle exits monotonically downward. The valve is a check valve or a controlled valve. The valve maintains the fuel supply at a pressure such that fuel in the fuel supply is a continuous fluid phase. The fuel leaves the nozzle exits to the combustion chamber of the turbine engine.Type: GrantFiled: December 27, 2011Date of Patent: June 7, 2016Assignee: Rolls-Royce North American Technologies, Inc.Inventor: Timothy C.
