  • Patent number: 4462619
    Abstract: A fluid coupling for interconnecting a liquid-conveying duct in a shaft element to a duct in a hub element, the two elements being rotatable relative to each other. The shaft element has a central passageway subjected to fluid under high pressure and has an enlarged-diameter end communicating with a smaller-diameter portion. The end of the large diameter portion of the shaft element remote from its small diameter portion is subjected to fluid under high pressure in said passageway; while the opposite end of the large diameter shaft portion is subjected to a sealing fluid. The pressure of the sealing fluid is always greater than that of the high-pressure fluid, with the result that the high-pressure fluid will not enter the chamber filled with sealing fluid to decompose it and form an emulsion.

  • Patent number: 4449738
    Abstract: A rotary fluid coupling for conveying fluid from a stationary shaft to a hub rotatably mounted on the shaft, or vice versa. The coupling is characterized in having a shaft provided with an axial passageway extending therethrough, one end of the passageway being connected to a source of high pressure fluid and the other being connected to a source of high-viscosity sealing fluid (e.g., a lubricant). A piston in the passageway separates the high-viscosity sealing fluid from the high pressure fluid, the latter being conveyed to the surrounding hub through radial passageways formed in an enlarged diameter portion of the shaft. The high-viscosity sealing fluid is applied to both ends of the enlarged diameter portion of the shaft to form a seal which prevents escape of the high pressure fluid.

  • Patent number: 4108294
    Abstract: A rotary fluid coupling which is particularly suitable for connecting a stationary source of fluid pressure to a fluid-pressure operated clutch comprises inner and outer, concentric, relatively rotatable members which have a space between them constituting a generally annular chamber for receiving pressurized fluid. The chamber is sealed to prevent the leakage of fluid by a releasable sealing mechanism which is itself fluid-pressure operated. Passages extend through the two members to connect the chamber to the stationary and rotary fluid lines. Preferably, the inner member rotates relative to the outer member which may be held relatively stationary against rotation.

  • Patent number: 4098455
    Abstract: A rotary distributor seal for a rotary centrifuge which comprises a tubular housing having sealed ends, a relatively rotatable fluid conveying apertured spindle coaxially mounted in the housing, and several resilient, spaced ring seals positioned about the spindle to seal the annular space between the spindle and the housing, and to subdivide it into several annular chambers. Ports communicate with the chambers to provide fluid flow from the ports through the separate chambers and through the spindle. In accordance with this invention, support members are positioned in alternate, spaced chambers between pairs of ring seals to prevent collapse of the ring seal pairs together.

  • Patent number: 4037624
    Abstract: A spout assembly which includes a spout member fitted pivotally within a base. A fluid inlet is formed in the base whereby fluid may pass through the base and out the spout. The spout is preferably supported at both its internal and external diameters by the base so as to provide a more rigid assembly as well as to lengthen the life of the fluid seal between the base and spout.

  • Patent number: 4006924
    Abstract: The present invention is a swivel coupling. The coupling provides an effective seal by utilizing the fluid pressure present in the coupling. The fluid exerts pressure against one component of the coupling forcing it to seal against another component while permitting complete rotation of those components.

  • Patent number: 3954234
    Abstract: A restraint divestment system for releasing a crewman equipped with a parachute and restraint harness from an aircraft ejection seat mounted restraint assembly in the event of a ground emergency. A single point crewman actuated mechanism releases the leg restraints, seat lap belt, and the disconnect couplings connecting the parachute riser and shoulder straps and survival kit to the harness so that, in the event of a ground emergency, the crewman can escape from the aircraft with his harness. The actuating mechanism includes an interlock which prevents release of the parachute risers and survival kit in the event of an emergency ejection from the aircraft when in-flight, so that the system can then be utilized by a crewman for manual seat separation and parachute descent. The actuating mechanism includes a pull cord actuated bell crank mechanism which actuates the various release mechanisms and is latched in its full release position.
