Wear-resistant electro-pneumatic converters are disclosed. An electro-pneumatic converter includes a body including an axial passageway extending between a first opening and a second opening, the first opening associated with a supply port, the supply port to receive pressurized fluid from a pressure supply source, a solenoid disposed within the axial passageway, an armature including a first side and a second side opposite the first side, the second side facing the solenoid, the armature movable between a first position and a second position, the pressurized fluid blocked from flowing through the output port when the armature is in the first position, the pressurized fluid to flow through the output port when the armature is in the second position, and a spring coupled to the first side of the armature, the spring to bias the armature toward the first position.

A cryogenic valve includes a first port and a second port, a valve body, a valve stem, a sealing member, a valve element and a housing. The valve body includes a valve seat defining a fluid orifice in fluid communication with the first port. The valve stem is configured to engage with the valve body, wherein at least one of the valve stem and valve body form an inner valve cavity. The valve element is positioned within the inner valve cavity. The valve element is also configured to bias the sealing member against the orifice to substantially block flow through the orifice and the first port. The bias is controlled in response to control of the valve element by a valve actuator. A channel is configured to allow fluid flow through at least one of the valve stem and valve element along a longitudinal axis. A housing is configured to substantially seal and enclose at least a portion of the valve body and valve stem. The housing forms an inner housing cavity configured to thermally isolate the exterior of the valve body and valve stem from the housing.

In at least some implementations, a solenoid valve includes a housing, a bobbin and an armature. The bobbin is received at least partially within the housing and has a body about which a coil is provided. A fluid flow path including an inlet and an outlet and a valve seat is defined by at least one of the housing or the bobbin, and the armature is moveable relative to the valve seat to control flow through the fluid flow path.

The invention relates to a valve device (100) for a gaseous medium, in particular hydrogen, comprising a valve housing (6) and a solenoid armature (14) which is arranged in the valve housing and can move along the longitudinal axis (18) and which interacts with a first sealing seat (32) in order to open and close an outlet opening (40). Furthermore, the valve housing (6) is equipped with a second solenoid armature (16) which can be moved along the longitudinal axis (18) and which is at least partly received in a recess (38) of the first solenoid armature (14), and the second solenoid armature (16) interacts with a second sealing seat (34) in order to open and close an outlet opening (20) formed in the first solenoid armature (14). The first solenoid armature (14) and the second solenoid armature (16) are additionally surrounded by a magnet device (11), by means of which the first solenoid armature (14) and the second solenoid armature (16) can be moved along the longitudinal axis (18) using precisely one solenoid (10).

The invention relates to a tank device (1) for storing a gaseous medium, in particular hydrogen, comprising a valve device (2) and a tank (10). The valve device (2) comprises a valve housing (20) having a longitudinal axis, in which valve housing (20) an interior (7) is formed. An actuation valve element (18) movable along the longitudinal axis (11) is arranged in the interior (7), which actuation valve element (18) interacts with a valve seat (40) in order to open and close an outlet opening (31) and thus forms an actuation valve (44). The valve device (2) comprises a solenoid (14). Furthermore, the valve seat (40) is formed downstream on the valve housing (20) and at the outlet opening (31), and the cylindrical outlet opening (31) leads into a cylindrical passage channel (80), the diameter D of the passage channel (80) being greater than the diameter d of the outlet opening (31).

The present disclosure discloses an electromagnetic regulating valve with a check function. The valve may effectively regulate the flow in a valve body. Due to different lengths and taper angles of a valve flap group, the flow can be regulated more finely, and a medium can be prevented from backflow by a check function when necessary. Meanwhile, a mesh structure of bases of valve flaps can effectively reduce the instability of flow field motion so as to achieve an effect of rectifying.

In a fuel gas circulation apparatus, a diffuser is accommodated in an attachment hole of a body. An injector is provided upstream of the diffuser through an attachment. A vibration absorption member made of elastic material is provided between a proximal end of a large diameter portion of this diffuser and a distal end of a main body in the attachment, and a ring member is provided adjacent to the vibration absorption member.

A fuel metering valve includes a main flow path extending axially between an inlet and an outlet. Also included is a plunger disposed around a portion of a plunger guide, the plunger and the plunger guide configured to translate between an open position and a closed position to selectively distribute a fuel flowing through the main flow path to the outlet of the fuel metering valve. Further included is a solenoid coil disposed between a solenoid outer body and a solenoid inner body, the solenoid coil configured to magnetically attract the plunger to the open position. Yet further included is a secondary flow path for routing a stagnant volume of fuel upon translation of the plunger from the closed position to the open position.
