| 20100282332 | High-Pressure Fluid Safety Valve - A safety valve for a fluid circuit under pressure (P), the valve comprising a body (2), a piston (3) able to move with respect to the body between a closed position and a purge position. A thermally deformable element (5) acts to cause the piston to move from the closed position to the purge position above and beyond a purge temperature so as to connect the circuit to a discharge duct (16). The valve further comprises an overpressure relief device sensitive to the pressure of the fluid and configured to connect the circuit to the discharge duct when the pressure (P) of the circuit reaches a trip pressure. | 11-11-2010 |

| 20080264494 | Exhaust Apparatus Pressure Control System - A pressure control system is disclosed. The control system in one embodiment includes a main body comprising a pilot chamber wherein an intake port and a discharge port are formed, and a spool comprising an upper slide and a lower slide. The spool in this embodiment is attached by a spring to the upper part of the main body. The exhaust apparatus pressure control system includes an absolute pressure sensor for detecting the pressure in the intake port and a differential pressure sensor for detecting the difference between the pressure in the intake port and atmospheric pressure; a control valve for supplying a pressure regulating gas to the pilot chamber; and a control circuit for sending switching signals to the absolute pressure sensor and the differential pressure sensor, and driving the control valve based on the output from the absolute pressure sensor or differential pressure sensor. | 10-30-2008 |
| 20090038688 | Fluid Control Valve - A fluid control valve for use in a system for inflating an anti-G garment. The valve includes an elongate chamber in which a valve member is moveable. The chamber has first and second axial ends. An inlet opening in a chamber wall provides for the flow of fluid into the chamber. A valve edge is provided at the second end of the chamber to form an outlet. The valve member has a first portion which closes the first chamber end and is moveable in the chamber between the inlet opening and the first chamber end, an intermediate portion which has a cross sectional area less than that of the chamber wall to permit the inflow of fluid to the chamber, and a second portion including a flow control device which co-operates with the valve edge to control fluid flow from the valve. | 02-12-2009 |
| 20130312843 | PRESSURE AND FLOW ALTITUDE COMPENSATED SHUTOFF VALVE - A pressure and flow altitude compensated shut off valve includes a valve body, a valve element, and an altitude compensation pilot valve. The valve body has an inlet port, an outlet port, and a flow passage extending between the inlet port and the outlet port. The valve element is disposed within the flow passage and is responsive to fluid pressure at the inlet port to move between a closed position, in which fluid may not flow through the flow passage, and a plurality of open position between the closed position and a full-open position. The altitude compensation pilot valve is coupled to the valve body and is responsive to pressure variations at the second port to control the fluid pressure at which the valve element moves to the closed and open positions. | 11-28-2013 |
| 20140034146 | DEVICE FOR ACTIVATING A PASSIVE EJECTOR VALVE FOR PRESSURISING A TURBOJET ENGINE CHAMBER FOR AN AIRCRAFT - An apparatus for activating a valve of an ejector in order to adapt the pressurisation of a chamber in an aircraft turbojet engine comprising a device constructed and arranged to trigger the opening and/or closing of valve and/or the power of the valve as a function of the altitude at which the valve is located. | 02-06-2014 |

| 20140014195 | WATER-INFLOW PREVENTION DEVICE OF AIRCRAFT, AIR PRESSURE REGULATING VALVE FOR AIRCRAFT, AND AIRCRAFT - A water-inflow prevention device is provided by installing a closing lid | 01-16-2014 |
| 20140069514 | WATER-PROOF STRUCTURE PROVIDED WITH INTERNAL BAROMETER FOR TERMINAL DEVICE AND METHOD FOR CONTROLLING A WATER-PROOF STRUCTURE - A water-proof structure has an internal barometer for a terminal device. The water-proof structure is an internal cavity of the terminal device. The water-proof structure is provided with an opening on a casing of the terminal device. Abarometer is arranged inside the water-proof structure. A water drop detection device is arranged between a water-proof mesh net and the barometer. The water drop detection device is electrically connected to a control valve, and when a water volume detected by the water drop detection device reaches a water volume threshold value, the control valve is closed. | 03-13-2014 |
| 20150330526 | APPARATUS FOR SHUTTING OFF FLOW OF WATER THROUGH DUCTWORK - An apparatus for shutting off the flow of water through ductwork is disclosed that is installed in an air conditioning duct in a building and closes the air conditioning duct in the event of the attack of seawater. Two upper and lower hinged door bodies disposed in the inside of the air conditioning duct are supported by a support device in the state in which the inside of the air conditioning duct is open. The opening and closing operations of the upper door body are interlocked with the opening and closing operations of the lower door body by a chain. A water intrusion detection device releases the supporting of the two upper and lower door bodies in the event of the intrusion of water. The two upper and lower door bodies are horizontally moved in the direction of water pressure when the inside of the air conditioning duct is closed. | 11-19-2015 |
