摘要： A fluid control valve includes a housing body, a valve member, and a cap. The housing body includes a pipe part and a valve housing part. The valve housing part includes a valve opening, a pair of flat surfaces and an open end. In addition, the valve housing part houses the valve member configured to open and close the valve opening. The valve housing part has a central axis oriented perpendicular to a central axis of the pipe part. The cap closes the open end of the valve housing part. The flat surfaces are formed on opposite sides of a plane including the central axis of the valve housing part and the central axis of the pipe part. Each of the flat surfaces extend perpendicularly to the central axis of the valve housing.

摘要： A tensioner capable of keeping oil pressure in an oil pressure chamber stable is provided. In the tensioner, a flow amount control mechanism includes a flow amount control member set inside a control space so as to be able to approach and separate from the oil pressure chamber, a control biasing unit, a first restricting part and a second restricting part. The flow amount control member and the inner wall of the control space are provided such that the flow resistance of a first control flow passage, which is exhibited when the flow amount control member contacts the first restricting part, is larger than the flow resistance of a second control flow passage, which is exhibited when the flow amount control member contacts the second restricting part.

摘要： A high pressure tank of a high pressure tank apparatus includes: a resin-made liner; a reinforced layer; a supplying/discharging hole to which a supplying/discharging flow path is connected via a connecting section; and a supplying/discharging-side lead-out hole that leads out a fluid interposing between the liner and the reinforced layer. A leaked fluid storage section is capable of storing a leaked fluid that has leaked from the connecting section. A supplying/discharging-side discharge flow path is provided independently from the leaked fluid storage section, and, when an opening/closing valve opens, discharges to the air a temporary release fluid that has been led out via the supplying/discharging-side lead-out hole. A control section, when it has judged, based on a detection result of a detecting unit, that there is a condition enabling the temporary release fluid to be discharged, opens the opening/closing valve.

摘要： A pressure measuring system is provided in which a closing element supported in the pressure fitting channel is activated or displaced by a pressure surge or a pressure wave and thereby seals the channel to the measuring element and thus prevents an outflow of the fluid.

摘要： A valve assembly capable of converting a small leak of a device into a measurable, relatively larger or “burst” flow event is described. In certain embodiments, the valve assembly includes a compliant chamber and, following pressurization of the device, permits flow when the pressure in the compliant chamber drops to a configured fill pressure and restricts (or prevents) flow when the pressure in the compliant chamber increases to a shut-off pressure. The disclosed valve assemblies may be incorporated into a leak detection assembly capable of transmitting usage and/or alarm data to a central service.

摘要： A bleed valve for a gas turbine engine compressor has a valve body and a flapper. The valve body defines a flow path and includes a flapper seat. The flow path extends through the valve body. The flapper is pivotally connected to the valve body and is movable between a closed position and an open position. In the closed position the flapper seats against the flapper seat and blocks the flow path. In the open position the flapper is angled towards the valve body inlet such that fluid moving through the valve body exerts force on the flapper, urging the flapper towards the closed position.

摘要： Disclosed is a differential pressure valve comprising: a valve body, the valve body having at least one flow inlet and one flow outlet: at least one shutter, the shutter being movable between an open position and a closed position under a differential pressure across the valve; at least one flow passage from the flow inlet to the flow outlet; at least one biasing member configured to bias the shutter towards a closed position so as to block the flow passage through the flow inlet. The biasing member is a non-linear biasing member.

摘要： An oil return mechanism includes a base, a control switch, a first blocking ball mounted in the base, an elastic member mounted between the first blocking ball and the base. The base has a liquid storing cavity, a liquid returning cavity, a communicating cavity, a first communicating opening communicating between the liquid returning cavity and the communicating cavity, and a second communicating opening communicating between the communicating cavity and the liquid storing cavity. The present invention can regulate a speed of a fluid flowing from the liquid returning cavity to the communicating cavity, and has the advantages of simple structure and great reduction of cost.
