摘要： A female coupling member includes a body portion, a slideable sleeve positioned in the body portion and an axially extending stem valve sealingly engageable with the sleeve. Axial movement of the sleeve relative to the stem valve opens the female coupling member to the flow of fluid. The stem valve is provided with a cavity sized to receive a protruding nose of a male member to be attached thereto. The slideable sleeve and the stem valve are designed to receive the male coupling member including its flat insertion end and protruding nose with minimal air inclusion and minimal fluid loss upon disengagement.

摘要： A valve mechanism for a needleless connector employs a deformable piston having a piston head of elliptical cross-section with a marquise-shaped bore formed along its longitudinal axis wherein the major axes of the respective generally elliptical shapes are oriented perpendicular to one another. The piston head is captured within the connector housing and is reciprocal between a section of reduced diameter adjacent the connection port and a section of enlarged diameter. Constraining the piston head into the section of reduced diameter causes the elliptical bore to be squeezed shut while positioning the piston head in the section of enlarged diameter causes the piston head to relax and assume its natural elliptical shape, while the bore similarly regains its natural open shape to provide a fluid path therethrough. A compressible or extendible section affixed to the piston head serves to bias the piston into the section of reduced diameter. A tapered section of the piston contacts the housing to secure the top of the piston flush with the top of the housing for ease in cleaning.

摘要： A device for transferring and withdrawing liquids or liquid media from bottles, pouches or similar containers for medical purposes. The device includes a first rotationally-symmetric body including a threaded cam, a first spike with a tip, a first main duct extending to the tip, and a first auxiliary duct extending to the tip. The first auxiliary duct narrows to a capillary-like opening adjacent to the tip. A second rotationally-symmetric body is provided which includes a second spike with a second main duct and a second auxiliary duct. The first body is centrically plugged into the second body wherein the first spike is diametrically disposed with respect to the second spike. The first and second main ducts form a substantially linear, axially extending flow path through the device. The first and second bodies include a recess formed between the first auxiliary duct and the second auxiliary duct. A separate filter housing is connected to the threaded cam of the first body following the removal of the second body. A sealing surface on the filter housing is sealed against the first body with the filter of the filter housing disposed transverse to the axially extending flow path.

摘要： An automatically releasable shut-off coupling, for use in high pressure fluid applications, has matable and separable stationary and break-away modules forming a housing having a substantially straight throughpassage. An intermediate carrier member is slidably retained within the stationary module for movement from a retracted position to an extended position, upon application of a threshold value force by the break-away module. A locking element is retained in a first recess in the intermediate carrier member for movement between a locked position, corresponding to the retracted position of the intermediate carrier member, at which locked position the locking element partially enters a cooperating second recess in the break-away module, thereby to preclude movement of the break-away module relative to the intermediate carrier member, and an unlocked position, corresponding to the extended position of the carrier member, at which unlocked position the locking element is in register with a cooperating third recess in the housing of the stationary module. First and second ramp portions disposed on the second recess and the locking element, respectively, contact each other when the intermediate carrier member is in its extended position, such that the locking element is forcibly ejected radially outwardly from the second recess, thereby permitting movement of the break-away module relative to the intermediate carrier member. Fluid flow precluding valves block the throughpassage when the stationary module and the break-away module are separated one from the other.

摘要： A fluid coupling, e.g., a subsea coupling, includes male and female parts which can be coupled together. The female part includes four passages normally closed by a slidable gate. The male part includes four passages normally closed by a closure slide. When the male and female parts are coupled together, the gate is pushed aside by the gate part and becomes temporarily joined thereto, and the closure slide is pushed aside by the female part and is temporarily joined thereto. When the male and female parts are uncoupled, the gate and closure slide are moved back to their passage-closing positions. A metal sealing member for the passages includes annular thick and thin lips. The thin lip provides flexibility, and the thick lip engages a relatively movable part.

A pressure reduction member is arranged in the pressure reduction channel. The pressure reduction member includes a shut-off element arranged in the pressure reduction channel. A seat includes a seat surface, wherein in a closed position a first portion of the shut-off element surface bears against the seat surface. The seat surface substantially corresponds to the shut-off element first surface portion.

摘要： A breakaway unit which is adapted to be mounted in series flow relation with a fuel nozzle. The breakaway unit comprises a flex section which assures an axial transmission of forces to a valve section which is separated when a vehicle drives away from a dispensing unit with the nozzle lodged in its fuel tank. The valve section comprises inlet and outlet couplers and means for releasable locking the couplers in an assembled relation. These means comprise fingers which are flexed outwardly when a separating force exceeds a predetermined value. Garter springs embrace the fingers to accurately control at which the couplers will separate. The fingers engage angularly spaced lugs which permit the fingers to be telescoped therebetween and then rotated to a locking position to facilitate reassembly of the couplers with a minimum of effort. Alternate embodiments of the invention disclose other forms of spring means for accurately controlling the force at which the couplers will separate. Also disclosed are alternate constructions which minimize the effort required for reassembly.
