摘要： A liquid chemical dispenser for an irrigation system comprises a removable supply container for the chemical which, in a first embodiment, comprises a valve for preventing spillage of the chemical during attachment of the container to the dispenser. This feature allows the container to be mounted in an inverted position on the dispenser without loss of its contents. In a second embodiment, the chemical container comprises a membrane which is pierced by a dip tube when the container is attached to the dispenser. A section of the dip tube produces an annular vent passage in the membrane around the dip tube to provide vacuum relief. The configuration of the containers substantially reduces the chance of inadvertent contact with the contents and the simple design permits the containers to be disposable.

摘要： A poppet valve for a hydraulic coupling member has an internal, spring-loaded check valve (which may be a ball check valve) in fluid communication with a bleed passage. The check valve may be configured as a pressure-relief valve which bleeds off excess hydraulic fluid pressure within the coupling member to a preselected value. A poppet valve according to the invention may be used in female coupling members and/or male coupling members. Certain embodiments of the invention may be retrofitted to coupling members of the prior art.

摘要： A female hydraulic coupling member includes a bidirectional, pressure-energized probe seal for sealing between the body of the female coupling member and the cylindrical probe section of a male coupling member seated in the receiving chamber of the female member. In one embodiment, the pressure-energized seal comprises a first curved section which is oriented towards the external end of the receiving chamber in which it is installed and a second curved section oriented towards the interior end of the receiving chamber. The two curved sections are joined by a substantially straight back section. When the pressure of fluid within the coupling member is above the ambient fluid pressure, the first curved section is pressure-energized so as to increase its sealing effectiveness. When external pressure (e.g., the hydrostatic head) exceeds the pressure of fluid within the coupling member, the second curved section is pressure-energized so as to increase its sealing effectiveness. In another embodiment, the pressure-energized seal comprises a curved back section joining the first curved section and the second curved section. When the curved back section moves radially outward against a circumferential wall under the influence of fluid pressure within the seal, it effects a slight rotation of the first and second curved sections, thereby increasing their sealing effectiveness.

摘要： A probe seal for a female hydraulic coupling member has both internal and external pressure-energized seals. The outer wall or opposing ends of the seal have one or more pressure-energized seals for sealing between the body of the probe seal and the body of a coupling member in which the probe seal is installed. In certain embodiments, the generally ring-shaped probe seal has an annular fluid chamber in one or both end walls of the body of the seal. Hydraulic fluid under pressure may enter the annular fluid chamber and exert a generally radial force in response to a pressure differential. This radial force can act to increase the sealing effectiveness of the probe seal to the body of the female coupling member having such a probe seal. In “negative pressure” situations (i.e., when the ambient pressure exceeds the internal fluid pressure), seawater may enter an annular fluid chamber on the opposing end of the probe seal and similarly act to increase the sealing effectiveness of the probe seal to the body of the female coupling member. Annular, L-shaped, T-shaped or angled grooves in the inner wall of the seal form cavities and sealing projections that can be urged in an inward, radial direction by fluid pressure within an associated cavity to increase the sealing effectiveness between the body of the seal and the probe of a male hydraulic coupling member inserted in the receiving chamber of the female coupling member.

摘要： Male and/or female members of a hydraulic coupling have an internal poppet valve that is held in the closed position by a flat wire, helical compression spring. The spring is configured such that when the poppet valve is moved to its fully open position, the coils of the spring are completely compressed thereby forming a substantially smooth bore tube for the flow of hydraulic fluid. The flat wire, helical compression spring may also act as a valve stop, limiting movement of the poppet valve and providing the necessary resistance to move the valve actuator of a corresponding valve in a mating member.

摘要： A crown-type probe seal for a female hydraulic coupling member has one or more pressure-energized seals for sealing between the probe seal and the body of the coupling member which retains the probe seal. The generally ring-shaped probe seal has one or more annular fluid chambers in the wall of the seal's body. Each annular fluid chamber is open to the outer circumference of the probe seal. Hydraulic fluid under pressure may enter an annular fluid chamber through its opening an exert a generally radial force as a result of a pressure differential. This radial force can act to increase the sealing effectiveness of the probe seal both to the body of the coupling member retaining the probe seal and to the probe of a male coupling member inserted in the receiving chamber of the female member.

摘要： A coupling for tubular goods having male and female coupling halves adapted to provide a straight-through conduit path when joined together. In a preferred embodiment, the male member has a sliding gate which opens automatically when the coupling halves are mated and closes off the central passageway automatically when the coupling halves are separated. The gate prevents debris from entering the central passageway when the coupling is de-mated. This is a particular advantage in undersea environments. The coupling may include seals for providing a fluid-tight connection between the male and female members.

摘要： An undersea hydraulic coupling member having a seal retainer with a first inner ring and a second outer ring is disclosed. The first inner ring and second outer ring are concentric, at least part of the first inner ring inserted through the second outer ring. The second outer ring is threaded to the coupling member to provide sufficient torque to reduce or eliminate any gap between the seal retainer and the shoulder surface in the coupling member on which an elastomeric seal is positioned. Another elastomeric seal is held between the first inner ring and second outer ring of the seal retainer.
