摘要： A bearing and seal assembly for supporting a rotor for rotation about an axis in a rotor receiving bore of a rotating machine which is concentric to the axis of rotation. The bearing and seal assembly includes a nonrotatable bearing support member dimensioned to loosely fit inside the rotor bore so as to be radially movable relative to the axis of rotation. A bearing receiving portion is provided on the bearing support that holds a bearing which mounts the rotor on the bearing support member. A seal is nonrotatably mounted on the bearing support and has an outer peripheral portion dimensioned to have a close tolerance nonrotating fit with an inner peripheral surface of the rotor bore; an inner peripheral portion; and an nonrotating sealing surface dimensioned to have a close tolerance sealing relationship with a rotating sealing surface on the rotor. The bearing support has a radial dimension that is less than the radial dimension between a radial outer portion and an inner peripheral surface of the bore to permit radial adjustment of the rotor axis to locate a rotor sealing surface in concentricity with the nonrotating sealing surface of the seal. A releasable clamping device is provided for securing the members together to lock the rotor and seal surfaces in the position of concentricity.

摘要： In a disc-type stop valve, a valve disc located at the lower end of a rotatable valve stem takes the form of a solid cylindrical metal member having an annular groove formed around the periphery of its lower surface in which an annular resiliently deformable plastic seal ring is disposed. The seal ring is held in place by a smaller-diameter circular metal retainer plate which is secured by bolts against the lower surface of the valve disc and against the underside of seal ring. When the valve is closed, a circumferential lower edge of the seal ring bears against a conically-shaped annular metal valve seat surface in the valve body. A large-diameter resilient compressible conventional O-ring is disposed in an annular space defined by the rear side of the retainer plate, the annular inner edge of the seal ring and a chamfered edge along the intersection of the lower surface and the side edge of the valve disc. The O-ring operates, when compressed, to effect a seal in a space between the seal ring and the retainer plate valve disc without requiring maximum compression of the seal ring. Furthermore, when the valve is in operation and partially cracked open, fluid at high pressure is prevented by the O-ring from getting behind the seal ring and forcing it laterally outwardly further increasing the possibility of leakage fluid leakage. A vent hole for pressure relief extends through the valve disc and communicates with the space between the valve disc and the seal ring to insure inner and outer edges of the seal ring are at equal pressures.

摘要： A large manually operated leak-proof corrosion-proof low-cost shut-off or stop valve for handling high pressure refrigerant liquid and/or gases is disclosed. The valve comprises a valve body formed of two sheet metal hemispheres electron-welded to the periphery of a circular metal valve plate which has an aperture therethrough. Hollow cylindrical metal tubes entend into circular holes formed in the hemispheres and are electron-welded to the hemispheres along the edge of the circular holes. One tube on each hemisphere serves for fluid flow. Another internally and externally threaded tube on one hemisphere serves as valve sleeve through which a manually rotatable and axially shiftable externally threaded valve spindle extends. The inner end of the valve spindle is secured to a valve disc which cooperates with the aperture in the valve plate. In the method, components to be welded together are assembled and rotated with respect to a stationary electron welding beam. The weld is formed solely of melted and resolidified materials from the components being joined. The electron welding beam is applied to the interior of each hemisphere to attach the metal tubes thereto. The electron welding beam is applied to the exterior of each hemisphere to secure it to the metal valve plate. This ensures that a weld extends entirely through the mating surfaces being joined.

摘要： A reciprocating type gas compressor comprises a hollow frame or housing having spaced apart end walls, a motor-driven crankshaft disposed within the housing and rotatably mounted on bearing assemblies on the end walls and connecting rods connected to crank pins on the crankshaft for driving pistons located within the housing. The crankshaft comprises a drive shaft at one end and a pump shaft the other end, both extending along a common axis of rotation. The crankshaft also comprises a pair of axially spaced apart counterweights located between the two shafts and a crank arm or link located between the counterweights. A crank pin extends from each counterweight to the link along a pin axis which is parallel to and spaced apart from the common axis of rotation. Each bearing assembly has a hollow cylindrical inner race which is friction-fitted on a shaft at an end of the crankshaft and abutts the side of one counterweight. To enable removal of each friction-fitted bearing assembly from its shaft without damage thereto, a pair of threaded bores extend through portions of each counterweight and the bore axes are parallel to but located on opposite sides of the common axis of rotation and each bore is aligned with the inner end surface of the inner race of the associated bearing assembly. Each threaded bore accommodates a long jack screw which is temporarily rotatably inserted thereinto so as to engage the inner race and force the bearing assembly off of its shaft for servicing or replacement.

The valve disc is secured to the valve spindle by a C-ring which engages an annular groove formed in the periphery of the cylindrical inner end of the valve spindle and a registering annular groove formed in the peripheral wall of the cylindrical recess in the valve disc. The outer end of the valve spindle is secured to the hub of a hand-wheel which is rotatable to open and close the valve. A hollow bonnet secured to the outer end of the valve sleeve entraps sealing materials to prevent fluid leakage between the valve spindle and the valve sleeve.

The cylindrical outer end of a valve spindle extends into a cylindrical bore in the hub of a hand-wheel which is rotatable to open and close the valve. The hand-wheel is secured to a valve spindle by a removable flanged roll pin which fits into a pin hole formed by mating or registering recesses formed in the periphery of the outer end of the valve spindle and in the peripheral wall of the bore in the hub of the hand-wheel. Unscrewing of the bonnet affords access to the sealing materials and, as the bonnet moves axially, it also shifts the hand-wheel off of the outer end of the valve spindle. As this occurs, the wheel hub engages the roll pin flange to force the roll pin out of the pin hole.

摘要： A refrigeration system comprises an evaporator which feeds uncompressed vapor to a first (low) stage compressor, a second (high) stage compressor which receives low compression vapor from the first stage and feeds high compression vapor to a condenser, and a receiver which receives liquid from the condenser and ultimately feeds it to the evaporator. Desuperheater apparatus, comprising a pressure vessel (subcooler) and a heat exchanger, is provided to remove excess heat (superheat) from the compressed vapor fed by the first stage to the second stage to thereby improve thermal efficiency of the system and to reduce the mass of refrigerant to be handled by the second stage thereby enabling use of a smaller, more economical second stage compressor. The pressure vessel contains a bath of liquid which is supplied from the receiver and then fed to the evaporator. Compressed vapor from the first stage is forced through and cooled by the liquid bath in the pressure vessel and is then fed to the second stage, along with vapor which evaporates from the liquid bath. The heat exchanger has one side through which compressed vapor from the first stage passes (and is cooled) on its way to the pressure vessel. The heat exchanger has another side through which an over-supply of liquid is pumped (or gravity fed) from the receiver and then returned to the receiver as a liquid/vapor mixture.

摘要： In a large refrigeration system comprising a screw compressor of controllably variable output, compressor lubricating oil, discharged from the compressor in a mixture with compressed refrigerant, is separated from the refrigerant at an oil separator from which it is returned to the compressor. Compressed refrigerant flows from the separator, through a condenser, to a high pressure receiver, where it is held for circulation through an evaporator and thence back to the compressor.Through a bypass conduit in which a small liquid refrigerant pump is connected, condensed refrigerant from the receiver is delivered to a duct communicating the compressor discharge outlet with the oil separator inlet, to cool the oil-refrigerant mixture before it enters the separator. A thermostat senses temperature of that mixture near the separator inlet and so controls a throttling valve in the bypass conduit as to maintain that temperature substantially constant.
