摘要： PROBLEM TO BE SOLVED: To keep a flow path communicated with a primary port 15 and a secondary port 16 in an opened condition even when primary pressure P1 of compressive fluid as gas is reduced in a normal state, and to change over it into a closed condition in an abnormal state when the flow amount of the compressive fluid flowing from the primary port 15 is a predetermined overflow amount or more with the breakage of a duct. SOLUTION: In a variable throttle valve part 12 laid in the flow path, a piston 21 greatly changes the opening of a through-hole 26 with the spring force of a spring member 22 as the primary pressure P1 is reduced so that differential pressure ΔP between pressure P1 on the side of the primary port 15 of the variable throttle valve part 12 and pressure P1' in a communication passage 18 on the side of the secondary port 16 is kept constant if the flow amount of the compressive fluid is constant, and the differential pressure ΔP is greater as the flow amount is increased. In an overflow preventing valve part 13 on the downstream side of the variable throttle valve part 12, the overflow piston 34 immediately changes over the flow path into a closed condition against the spring force of an overflow spring member 35 with the primary pressure P1 when the differential pressure ΔP is a predetermined preset differential pressure or greater.

摘要： PROBLEM TO BE SOLVED: To provide an excess flow preventing valve device capable of suppressing a trip flow rate from varying even when primary pressure varies.
SOLUTION: A variable throttle valve means 12 interposed in a valve passage 17 is controlled by a control means 14 so that it reduces an opening degree as the primary pressure P1 becomes higher and increases the opening degree as the primary pressure becomes lower on the basis of the primary pressure P1 detected by a detection means 13. When a difference in pressure between the pressure P1 on the side of a primary port 15 and pressure P1' on the side of a secondary port 16 in the variable throttle valve means 12 becomes a predetermined set differential pressure or over, the excess flow preventing valve means 40 interposed more on the the secondary port 16 side than the variable throttle valve means 12 of the valve passage 17 switches the valve passage 17 to a closed state.

摘要： PROBLEM TO BE SOLVED: To provide a simple sealing structure capable of preventing the leakage of a gas of wide pressure fluctuation and high pressure. SOLUTION: A resin sub-seal member 11 having a recessed groove 16 is mounted at a high-pressure side of a rubber main seal member 10, to prevent the transmission of pressure fluctuation to the main seal member 10, when the pressure of gas at high-pressure side is fluctuated. A fluctuation reducing space 13 is formed between the seal members 10, 11, so that the pressure fluctuation can be reduced by the fluctuation releasing space 13 even when the gas leakage at the sub-seal member 11 and the delay in response of the sub-seal member 11 to the pressure fluctuation occur. Whereby the sudden change of the pressure of gas around the main-seal member 10 can be prevented, the blister phenomenon can be prevented, and high sealability can be achieved. The simple structure can be realized as only the seal members 10, 11 and the fluctuation reducing space 13 are mounted. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a cutoff valve device suitably used in a wide primary pressure range and a wide range flow rate, in a two-stage type cutoff valve device utilizing pilot pressure.
SOLUTION: A cutoff valve part 21 is disposed to a main passage 25 making a primary port 27 communicate to a secondary port 28. The cutoff valve part 21 is opened/closed by using differential pressure ΔP between primary pressure Pin and secondary pressure Pout. An operation valve part 22 is disposed in a pilot passage 26 introducing pilot pressure into the cutoff valve part 21. The operation valve part 22 operates the pilot pressure to drive the cutoff vale part to be opened/closed. A differential pressure generating valve part 23 is disposed in the main passage 25 so that the position of the differential pressure generating valve part 23 is closer to the primary port 25 compared with the position of the cutoff valve part 21. Opening of the differential pressure generating valve 23 is changed depending on the primary pressure Pin and the flow rate Q when the cutoff valve part 21 is opened, so as to keep the differential pressure ΔP between the primary pressure Pin and the secondary pressure Pout approximately constant.

摘要： PROBLEM TO BE SOLVED: To provide a valve device in which the size in a radius direction can be reduced. SOLUTION: An opening/closing valve part and a pressure reducing valve part are arranged on a position where at least partial constitutions are overlapped to each other in the downstream direction of fluid. As compared with a case that the opening/closing valve part and the pressure reducing valve part are arranged simply in a column, the size of a device axial line L1 can be shortened. Since the the opening/closing valve part and the pressure reducing valve part are arranged on the same axis, a housing can be shared and the size of the valve device in the radium direction can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a structurally simple sealing structure preventing the leakage of gas whose pressure variation becomes large and high pressure.
SOLUTION: A resin sub-seal member 11 having a recessed groove 16 is arranged on the high pressure side of a rubber main seal member 10, and when the pressure of high pressure side gas varies, this pressure variation is prevented from being transmitted to the main seal member 10. A variation relieving space 13 is also formed between the respective seal members 10 and 11, and even if a response delay of the sub-seal member 11 to the leakage of the gas and the pressure variation in the sub-seal member 11 is caused, the pressure variation can be relieved by the variation relieving space 13. Thus, a sudden change in the pressure of the gas around the main seal member 10 is prevented, and the occurrence of a blister phenomenon is prevented, and high sealability is attained. The respective seal members 10 and 11 and the variation relieving space 13 are only preferably arranged, and can be achieved in a simple constitution.

摘要： PROBLEM TO BE SOLVED: To provide a highly reliable, smaller and simpler solenoid valve device. SOLUTION: Electric power is conducted to a coil 17 and a valve element 16 is driven to be displaced with magnetic operation to adjust the opening of a valve passage 43. The electric power for driving the valve element 16 is conducted to the coil 17 via a conductive wire 18. The conductive wire 18 is provided ranging from a portion of a housing 15 which is exposed from a tank 11 to a portion on which the coil 17 is provided, and it is held in the housing 15 in the state of being inserted through the housing 15. The conductive wire 18 is inserted through the housing 15 and held in the housing 15, so it is protected from external vibration and impact. The conductive wire 18 is therefore highly reliable in vibration resistance and impact resistance. The conductive wire 18 can be stored in the housing 15 in a neat fashion.
