Abstract: There is disclosed herein a valve and seal assembly comprising a valve body having a movable core housed therein adapted to allow the flow of material through the valve to be interrupted, and means for sealing the core and body so as to prevent leakage. The valve is sealed against leakage through the cooperation of a pair of O rings disposed at opposite ends of the rotatable member and metal bars extending axially between these O rings and engaging portions of the core and body. The metal bars are retained in grooves provided in either the core or body and are surrounded by a layer of resilient material on three sides thereof which urge the exposed metal portion out of these grooves and into a sealing engagement with the opposing core or body surface and also prevent material flowing through the valve from entering the grooves. A similar seal in the form of a ring is also contemplated for use in sealing a rotating shaft.

Abstract: A butterfly valve assembly having a corrosive resistant metal valve seat made of stainless steel or the like and supported in the passage of the body member of the valve assembly, the valve assembly further having a valve disc with an annular resilient sealing ring fixedly secured to the periphery thereof for cooperating with the valve seat. The valve seat is supported on the body member in such a manner that the valve seat may have limited axial movement relative to the body member when the valve disc is moved to the closed position so as to provide a compressive and/or fluid actuated seal between the valve seat and the body member whereby the butterfly valve assembly may be used in fluid distribution systems with the flow of fluid through the valve assembly being in either direction through the valve.

Abstract: This is a unitary all-plastic ball valve particularly for use with natural gas distribution lines which are plastic and buried in the earth, where the parts are designed to assure accurate assembly in order to provide a unitary sealed valve body impervious to most elements encountered, inside or outside the valve.

Abstract: A fuel injection system is disclosed for an internal combustion engine having at least one cylinder and a piston operating therein to define with the cylinder head a combustion chamber wherein air is compressed while the piston is moving to one end of its stroke. The system has pressurizing means adjacent the combustion chamber which suddenly further compresses in a compression chamber a small part of the air precompressed in the combustion chamber to a substantially higher pressure and temperature than the peak pressure and temperature of air in the combustion chamber. Fuel feed means supplies fuel to the compression chamber, and nozzle means is operative to substantially confine the air in the compression chamber during its compression and to discharge the compressed air-fuel mixture as a jet into the combustion chamber.

Abstract: A hydraulic circuit unit comprises parallel top and bottom faces and a side face for receiving a valve assembly. At least four passageways extend between the top and bottom faces and are perpendicular to them. The ends of the passageways open through the faces and the passageways are arranged with one at the center of a circle and the others regularly spaced around the circumference of the circle so that the unit may be rotated about the center of the circle to align the passageways with those of an adjacent similar unit in a plurality of positions. Connections extend between at least two of the passageways and a valve assembly positioned on the side face.

Abstract: A slide valve comprising a housing in which a slide is movably guided between two oppositely facing, flat contact surfaces. Communication between fluid passages in the housing is accomplished by hollow formed passage means on the slide. Seal rings carried in grooves in the slide maintain sealing contact between the slide and the contact surfaces of the housing and seal off the fluid passages relative to each other. Each seal ring consists of a band-shaped contact member and a resilient support member. The support member is arranged to bias the contact member against the contact surface by a force uniformly distributed over the entire length of the contact member.

Abstract: The specification discloses a flange valve having a metal valve body with a longitudinal central passage therethrough and annular flanges extending outwardly from the ends thereof. A truncated ellipsoid valve member is located in the central portion of the passage, the ellipsoid member having major and minor axes and being truncated at the opposite ends of the major axes. An aperture is formed through the ellipsoid member along the major axis. Annular resilient seats are disposed on opposing sides of the valve member to provide sealing between the interior of the valve body and the exterior of the valve member. A pair of removable annular liners are dimensioned to closely fit within opposite ends of the central passage of the valve body and include end portions abutting the resilient seats. The liners are constructed from non-corrosive material to prevent corrosion of the valve body.

Abstract: A main fluid pipe within a box-like housing has four auxiliary pipes connected thereto. Each auxiliary pipe extends to the outside of the housing. The first auxiliary pipe is connected to the drain of a swimming pool; the second is connected to the swimming pool pump; the third is connected to the skimmer and the fourth which extends upwardly is normally unconnected but closed by a valve. An adapter allows a standard garden hose to be connected to the fourth pipe for priming the pump and the swimming pool skimmer and drain lines. Chemicals may also be introduced into the fluid system through the fourth pipe. A thermometer, visible from the outside of the housing measures the temperature of the water within the pipe connected to the pump. The thermometer also measures the outside air temperature for comparison with the water temperature.

Abstract: A tapered plug valve comprises a casing having a passageway therethrough for the flow of fluid and a tapered bore intersecting the passageway. A tapered plug is rotatably mounted in the tapered bore and is adapted to block the passageway when the valve is in a closed position. The plug has a bore which is adapted to connect and be in communication with the passageway when the valve is in an open position. The plug and the casing define an apex chamber at the small end of the tapered plug and a base chamber at the large end of the plug. A seal is provided at the large end of the tapered plug to sealingly divide the base chamber into a first and second cavity. A pressurized medium is ported into the apex chamber and the second cavity and the first cavity is vented to atmosphere.

Abstract: The present invention relates to a device for accurately controlling the splitting and/or proportionalizing of a flowing liquid into two preset flows. The device is capable of maintaining the desired preset quantitative relationship between incoming and outgoing flows regardless of the flow characteristics of the incoming liquid. The incoming liquid is directed to a distributor located within a collector housing and regardless of the incoming flow rate, is fed uniformly in the form of a flat sheet or curtain into the collector(s). The collector is divided into two collector chambers by partitions located on opposite sides of a central column with the flow distributor connected to a shaft rotatably mounted within the central column so as to place one of the partitions in the flow path of the liquid emerging from the distributor, thereby splitting that flow.
