Abstract: A faucet for a liquid container includes a tubular housing which is mounted in an opening in the container and a tubular valve which is slidably mounted in the housing. The tubular housing includes open front and rear ends, and the valve extends forwardly from the front end of the housing. The valve includes a dispensing opening, and the valve is movable between a closed position in which the dispensing opening is positioned rearwardly of the front end of the housing and an open position in which the dispensing opening is positioned forwardly of the front end of the housing. A first seal is mounted on the front end of the valve forwardly of the dispensing opening for sealingly engaging the front end of the housing when the valve is closed, and a second seal is mounted on the rear end of the valve for sealingly engaging the housing as the valve is opened until the dispensing opening is at least partially open.

Abstract: A fluid flow regulator includes a resilient hollow sealing body which is fitted in the bottom part of a liquid housing adjacent to a tubular outlet end and which has a central through-hole to communicate to one another the chamber of the housing and the outlet end. An annular flange which extends from the top of the sealing body toward the through-hole forms a valve seat against which a float valve can be efficiently and tightly seated. A movable tube is inserted in the tubular end to be used to manually release the float valve from the valve seat.

Abstract: A valve for dispensing fluid products includes a valve body comprised of a first portion including a first open ended passageway therethrough, and a second portion having a second passageway open at a first end and substantially closed at a second end. A port in the side wall of the second portion is disposed so that the first and second passageways are disposed in fluid communication with each other. A handle is operatively connected to the body and extends partially into the second passageway. A generally tube-like seal member is closely housed in the second passageway and is adapted to close the port for blocking fluid communication between the two passageways. The seal member is selectively shiftable by the handle between a first, normal position in blocking relation to the port and a second position in spaced relation to the port. The valve body and handle may be integrally molded with each other from a plastic material.

Abstract: Disclosed is a tubing valve which may be used for selectively closing passages through tubular members and the like. The valve includes first and second housing members which may be mutually moved and which carry a latch assembly for limiting such movement between a first configuration and a second configuration. Each of the housing members further includes a valve member wherein the two valve members may be in mutual sealing engagement with the housing members in the first configuration. The valve members are not in sealing engagement with the housing members in the second configuration, thereby permitting fluid communication, for example, through the tubular passage. At least one of the valve members comprises a piston in sliding, sealing engagement with the corresponding housing member whereby fluid pressure within the tubular passage urges sealing engagement between the first and second valve members when the housing members are in the first configuration.

This valve body includes a longitudinal passage with a first section having its innermost end provided with a recessed valve seat. A second section of the passage is of larger diameter for receiving an adjustable valve sealing cap by means of a threaded connection. Positioned within the second section is a valve element for cooperation with the said recessed valve seat. The sealing cap has an innermost end provided with a second recessed valve seat in cooperation with a longitudinal passage through the cap that includes a compression spring that normally bears on the valve element to seal the valve element against the first recessed valve seat.

Abstract: A tap operated by a push button which acts to open a valve member which is biassed to the closed position, the valve member being for normal operation of the tap; also operated by the push button is a seal piercing means which pierces a diaphragm in or adjacent the tap inlet and which after initial operation of the push button remains lodged in the pierced diaphragm, the piercing means only being moved by the push button on the initial operation. The arrangement ensures an added protection against oxygen penetrating into a container fitted with the tap and is particularly useful for wine containers where the added protection ensures a longer shelf life.

Abstract: A subsea test valve system for well completed at the floor of the sea includes a safety valve and disconnect mechanism mounted in a blowout preventer at the bottom of the sea and having hydraulic fluid pressure operated means for opening the safety valve and controlling a latch in the disconnect mechanism. A tubing test string shut off valve is releasably latched in the disconnect mechanism and has a hydraulic fluid operated shut off valve and a valve for venting the test string to the riser pipe which extends from the blowout preventer to the vessel or platform at the surface of the sea. The subsea hydraulic pressure operated devices are supplied with pressure fluid from a subsea accumulator under the control of subsea pilot valves which are operated by small pressure differences, to accomplish rapid operation at great depth from a control console on the vessel or platform.

Abstract: Apparatus for controllably transferring fluid from a pierceable pressurized container includes a valve body, a stem member which is threadably connected to the valve body at one end and a fluid-conducting hose at the other end, and an elastomeric valve ball disposed in a cavity between the body and the stem member. The valve ball controls fluid flow from the container through the valve body and stem member to the hose in response to rotation of the valve stem relative to the body. Simultaneously, the valve balls acts as a check valve to prevent flow of fluid to the container. An O-ring seal between the stem and the valve body is adapted to leak at high pressure and bleed off fluid.

Abstract: A connection device for connection to first and second fluid conduits for providing selective fluid communication between the two conduits. The connection device comprises a first member having first and second open ends and a fluid passageway therebetween, and a second member having a first open end and a second end with a fluid passage defined therebetween and in which the second end is disposed within the second open end of the first member. The first and second members are movable relative to one another between an open position in which the first fluid passageway in the first member and the second fluid passageway in the second member are in fluid communication with one another, and a closed position.

Abstract: Valve apparatus may comprise a first tubular member; a second tubular member telescopically engaging the first tubular member for axial movement between a retracted position and an extended position, the first and second tubular members forming flow passage through which fluid communication may be established between the opposite ends of the apparatus; ports through the walls of one of the tubular members by which fluid communication may be established between the flow passage and the exterior of the valve apparatus; and a closure assembly carried by one of the tubular members for selectively opening and closing the ports to permit or prevent fluid communication with the exterior of the apparatus. Methods of using the valve apparatus in remedial oil and/or gas well operations are also disclosed.

Abstract: An equalizing valve is incorporated in a subsurface shutoff valve for wells and has a number of balls loosely confined in an annular groove in the tubular valve body and adapted to seat in by-pass ports in the shutoff valve actuator piston sleeve to prevent flow through such by-pass ports from ports in valve body which communicate with the groove. Actuation of the piston sleeve to open the shutoff valve causes a shoulder forming the groove to wipe the seated balls from the by-pass ports to equalize fluid across the shutoff valve before it is opened. The shutoff valve is of the ball type or of another type. The shutoff valve of the ball type, when closed, subjects its support bars to a force deforming them to allow the shutoff valve ball to move into seating engagement with a seating sleeve to prevent extrusion of an elastmer seal.

Abstract: A specific embodiment provides a valve structure for an evacuator system adapted to be connected to a source of negative pressure. The valve structure includes an elongated housing having a longitudinal bore extending through the housing, and a valve seat formed by a reduced diameter portion of the bore. A valve member is situated in the bore for abutting engagement with the valve seat to prevent passage of flowable materials therebetween. Biasing means is provided for urging the valve member into abutting engagement with the valve seat. A manually operable member is operatively associated with the biasing means for moving the valve member out of engagement with the valve seat to permit passage of flowable materials therebetween.

Abstract: A self-sealing dispensing valve for use on various containers. It is a simple two-piece device consisting of an outer housing having a dispensing outlet and an inner complemental valve member which ordinarily closes the outlet but which can be moved by finger pressure to open the outlet, and which will automatically return to its closed position when opening pressure is released. The housing has a flexible dome-shaped outer wall which embraces and is attached to a complemental dome-shaped rigid wall at the outer end of the valve member, which also has an axially inwardly extending flared sealing skirt. The skirt normally seats on the outlet, which extends radially through the correspondially tapered housing, but will be displaced axially inwardly to open the outlet, upon inward axial pressure on the outer dome-shaped flexible housing wall. Internal container pressure aids in the normal seating of the valve member.
