An electromagnetic positioning device includes an armature member for actuating a positioning partner and movable in an armature space relative to a stationary core (30). The armature member conducts magnetic flux upon energization of a stationary coil (32). The coil has a coil support with a winding and at least one external contactable connector (46) embedded at least in sections in the core and/or surrounded by the core. The core has an end surface (34), which is planar at least in sections, for interacting with the armature member. The core and the coil are embedded in and/or surrounded by a one-piece pot-like and/or cup-like housing (38) made of a material suitable for deep-drawing in such a manner that the core rests on a membrane-like, continuous and closed base section of the housing, the base section realizing a boundary surface of the armature space.

An electromagnetic valve has a valve housing; a valve body disposed inside the valve housing and movable in a reciprocating manner; an urging member configured to urge the valve body in one direction; and a drive device which is connected to the valve housing and applies a drive force to the valve body. A drive rod of the drive device includes a guide portion which faces an inner peripheral surface of a fixed iron core such that a movement of the drive rod is guided in an axial direction and a groove portion which is recessed in an inward radial direction from the guide portion and the groove portion is continuously formed from an inside of the valve housing to an inside of a movable iron core.

A valve assembly is disclosed, which includes a valve body defining a valve chamber and a moveable member. The moveable member has a valve element at its first end and an armature at its second end. The moveable member is moveable in an axial direction to selectively open and close the valve. The entire moveable member is spaced from the walls of the valve body when the valve is open or partially open. A flexible membrane forms a seal against the moveable member and the valve body to divide the valve chamber into a flow chamber in which the valve seat and valve element are located and a pressure compensation chamber within which the armature is entirely enclosed. A first fluid port is fluidly connected to the pressure compensation chamber via one or more bores in a pressure compensation flow path with at least one opening extending into the pressure compensation chamber at an axial position between the armature and the flexible membrane. The pressure compensation flow path includes a first axial portion with a first cross-sectional area and a second axial portion with a second, smaller cross-sectional area.

An isolation valve includes: a housing including a first passage and a second passage; a main valve assembly including a valve disposed in the housing such that a fluid flow between the first passage and the second passage is blocked; a locking assembly disposed in the housing, and including a release element configured to open the valve and a locking element configured to close the valve; and a bobbin assembly configured to be disposed in the housing and to operate the locking assembly, and including a coil; a core disposed inside the coil and including a space therein, the space including a closed end and an opened end; and a plunger configured to move in the space by an electromagnetic force generated by the coil and to contact the locking assembly on the opened end side.

A valve (1) for fluids, preferably for gases, comprises an inlet passage (2); an outlet passage (3); a shutter (4) interposed between the inlet passage (2) and the outlet passage (3) and movable between an open position and a closed position; actuating means (26,27). The valve (1) also comprises actuating means (26,27) operatively active on the shutter (4), which comprises an electromagnet (26) and a ferromagnetic element (27) that is movable as a function of the field generated by the electromagnet (26) for displacing the shutter (4) along the movement direction (L). In particular, the actuating means comprises a tubular body (5) made of non-magnetic material in which the ferromagnetic body (27) is inserted.

A double flow rate gas solenoid valve has an inlet and at least a first outlet in a housing. First and second solenoids are selectively operable relative to first and second valve seats to establish first and second gas flow paths, respectively. The second flow path has a restriction thereby resulting in a lower gas flow rate through the second flow path than the first flow path. When connected to a common inlet of a burner, at least two, if not three flow rates can be provided by the valve.

An electromagnetic valve has a solenoid, which includes a coil, a plunger, a fixed core, and a plunger spring. The fixed core is E-shaped and has a base, a first outer leg, a second outer leg, and a central leg. The first outer leg, the second outer leg, and the central leg extend from the base. The first outer leg has a first outer attraction surface configured to attract the plunger. The second outer leg has a second outer attraction surface configured to attract the plunger. The central leg has a central attraction surface configured to attract the plunger. The central attraction surface is larger in area than each of the first and second outer attraction surfaces.

A valve assembly (6000) for use with a valve body (7000) having a valve seat (7112) is disclosed, the valve assembly (6000) comprising: a cartridge (6200) threadably engaged with and extending away from the valve body (7000); a poppet (6500) slidably engaged with the cartridge (6200); a plate (6600) engaged with the poppet (6500); a plunger (6400) slidably engaged with the cartridge (6200) and slidably extending through the plate (6600); and a retainer (6450) captured between the plate (6600) and a surface of the poppet (6500), wherein the retainer (6450) is threadably engaged with the plunger (6400). The valve assembly (6000) can regulate fluid flow.

An adjustable damping valve device includes a coil carrier with a coil which is wound on an inner sleeve and which has two wire ends which protrude over a winding body. A back iron having a passage for a power supply line of the coil is placed on the coil carrier. The wire ends of the coil are co-located adjacent to one another in an outlet area of the coil carrier, and the back iron has a radial slot which extends from the outer edge of the back iron to the passage and has a width which corresponds at least to the width of the outlet area.

An aircraft includes at least one source collecting a set of navigational parameters of the aircraft, the at least one source obtaining flight data for the aircraft and including at least one of a global positioning system, an inertial reference system, or a sensor. The aircraft further includes a flight control computer communicatively coupled to the source and including a first processor and a first memory having a machine-readable medium, as well as a flight management system communicatively coupled to the flight control computer.
