In a solenoid valve, a desire valve stroke width may be set, and a flow rate may be returned to an original flow rate even when that the flow rate is changed. A solenoid valve includes a drive portion having a bobbin including a slidable hole formed there through, a fixed iron core disposed with in the bobbin and a movable iron core disposed to be slidable within the slidable hole, and a valve function portion having a valve body extending from the movable iron core and disposed in a leading end of a valve shaft passing through the fixed iron core and a valve seat with which the valve body is brought into close contact and from which the valve body is separated. In the solenoid valve, a predetermined gap width is formed between the valve body and the valve seat, when the solenoid valve is not energized, to open the valve, and the movable iron core is drawn to the fixed iron core when the solenoid valve is energized to close the valve. A valve stroke width may be adjusted by screwing a flow rate adjusting screw from an outer side in a rear end of the solenoid valve to bring the leading end into contact with a rear end surface of the movable iron core when the valve is opened, thereby adjusting a protrusion amount of the screw in the leading end of the slidable hole.

A system for maintaining pressure in the liquid fuel tank of a high-speed flight vehicle, such as a hypersonic flight, scramjet powered air and space vehicle, manages tank ullage using a pressure regulator coupled to the fuel tank that supplies pressurized gaseous media into the fuel tank ullage based on the internal pressure of the tank. The regulator has an on-board controller that processes tank pressure input to deliver a pulse-width modulated input signal to the coil of the on-board solenoid metering assembly. Energizing the coil drives the metering valve open against spring force. The metering assembly is contained in a removable cartridge that has a floating valve guide that is held stationary by bias of the spring against the metering valve. The metering valve has a separate valve seat that mates with the metering orifice of a flow nozzle. The valve seat can have higher compressibility than a clapper part of the valve to effect a better seal, with its compression being controlled by contact of the clapper with a rigid stop surface of the flow nozzle.
