Abstract: A hard seated globe valve assembly for use in servicing high and low temperature fluids. The valve includes a moveable stem attached at one end to a tapered plug of hard material. An equally hard seat having a tapered surface is mounted for mating engagement with the plug when the valve is closed. The seat is located in a partition that separates the globe-shaped body into two chambers having fluid inlet-outlet orifices. An annular ring is mounted between the bearing end of the stem and the plug so that the plug is resiliently engaged in the seat when the valve is closed. It has been found that hard seated valves tend to be difficult to open or lose their sealing abilities when servicing extreme temperature fluids due to the expansion and contraction when the valve is heated and cooled. The resilience of the annular ring prevents this problem by permitting the plug to adjust during expansion and contraction, thus making it easier to open the valve after cooling and precluding loss of sealing during heating.

Abstract: The valve of a liquid fuel pressure regulator comprises a two-part construction consisting of a spherically contoured element and a stem. The spherically contoured element serves to swivelly mount the valve on the movable wall which carries the valve. The spherically contoured element comprises a hole which is on a radial to the center of the element. The shank of the stem is press-fitted to this hole to dispose the stem's flat circular head toward a seat with which the valve coacts as the pressure regulator operates. The swivel mounting compensates for misalignment and out-of-squareness of the valve travel relative to the seat and enables the head to close flat against the seat. Two embodiments are disclosed. In one, the spherically contoured element is a sphere and the hole is a blind hole drilled into the sphere. In the other, the spherically contoured element is a truncated sphere and the hole is a through-hole.

The valve is provided with a locking device for locking the spindle axially undisplaceably at least in the closing position, in order to prevent unintentional opening of the flow path.

Abstract: An electromagnetic double-valve can synchronously regulate or control the ow of two materials without the need of a costly mechanical linkage between the two individual valves which may be arranged in a common housing. An armature serves as the valve body or plug in each valve and is held in one valve position by permanent magnets and is switched to the other valve position by a synchronously controlled electromagnetic coil or coils which are connected in series. When one armature is lifted quicker than the other by the electromagnet or magnets, then the total magnetic flux decreases, whereby the second armature is also lifted. The synchronization of the switching operation is enforced by the common, spacially closed magnetic flux through both armatures and by the common effect on both armatures by the electromagnetic coil or coils.

Abstract: A valve assembly has a rigid valve plate with a hole therein for receiving a stem member of the valve actuator. A resilient valve member is mounted on the rigid valve plate by having a peripheral portion overlapping the valve plate. To prevent high pressure gas from entering the hole around the valve stem member through the valve plate to distort the resilient valve member, a solid backup member is mounted inside the resilient valve member adjacent the rigid valve plate.

Abstract: An electromagnet used to operate a valve comprises an armature guided in a coil carrying body and equipped with an annular flange projecting into a recess in a buffer body with opposed limit faces to brake the movement of the armature in one direction before abutment of the pole faces and in the other direction a sealing of the valve opening. In the latter braking action the armature does not impact against the sealing surface due to a spring abutment of the valve member against the armature. The new electromagnet achieves a comparatively high degree of switch operation frequencies.

Abstract: A valve stem and disc for a disc-type valve assembly are held together by a retaining ring and constructed such that they may be assembled inside a valve housing while avoiding the possibility of the retaining ring binding upon either the stem or disc during assembly. The valve stem includes a truncated conical portion forming its distal end which acts to align the various valve members during assembly. In the method, the retaining ring is mounted on the valve disc first rather than on the valve stem. When the truncated conical end of the valve stem is inserted in the disc so as to spread the retaining ring until mating engagement is reached between the stem, the disc, and the retaining ring. The diameter of the truncated stem distal end is sized to preclude any binding on the retainer ring or disc during assembly.

The valve member is slidably mounted with respect to the power piston. A weak spring disposed between the valve member and the power piston normally seats the valve member on the valve seat and movement of the power piston will unseat the valve member to provide a pneumatic control function.

Abstract: A rotary control valve has a plug in the form of a cup shaped shell mounted on a bracket which is rotatable about an axis orthogonal to and offset from the central axis of a ring seat. This plug is connected to the rotatable actuating bracket by means of a threaded pin and nut so that the plug position can be adjusted with respect to the ring seat. Proper adjustment of the pin and nut allows the plug to be mounted in a fixed position on the bracket and enables the plug to be brought into and out of fluid tight sealing engagement with the ring seat without any bending or deformation taking place in the actuating bracket. The obtaining of this desired tight sealing engagement is aided by displacing the bracket axis from the plug center of curvature in the direction of the position occupied by the plug when in its sealing position, and by making the plug position adjustable along the bracket axis.

Abstract: An air by-pass valve with pressure relief feature is described. The valve is provided with inlet, outlet and by-pass or exhaust ports wherein two valve members are actuated by a diaphragm responsive to engine intake manifold vacuum to direct air from the inlet to the outlet or to the by-pass port as a function of engine intake vacuum and in which the valve members are mounted on a common diaphragm-actuated stem in such a manner that the by-pass valve member can move to open the by-pass port during over-pressure conditions without movement of the diaphragm or valve stem.

Abstract: An eccentrically rotatable control valve having a spherical shaped valve plug is positioned in a valve chamber to regulate the flow of fluid there through. The valve plug is retained in a loosely captured position by means of a bolt and spring to the end of a valve actuating arm for flexible, swivel movement thereon. This construction enables the plug to be initially rotated from a completely open position into line contact with a part of the valve seat in the wall of the chamber, and to then be jointly tilted and rolled about this seat part into and out of fluid tight surface to surface contact with the entire valve seat. The plug and arm are mounted on and for limited longitudinal movement with an associated valve actuator shaft that extends through the chamber. The latter construction provides a means by which the plug can center itself in a properly seated fluid tight position on the seat in the event that the valve seat is out of properly aligned seating surface engagement with the plug.
