The present invention relates to sealing valves that can be mounted within a container wall, enabling controlled fluid flow along both inner and outer surfaces of the sealing valve in the same distal direction.

A valve comprises a first housing including a first lumen extending therethrough and defining a first disk-facing surface and a second housing including a second lumen extending therethrough and defining a second disk-facing surface, the second housing being mated to the first housing so that the second disk-facing surface faces the first disk-facing surface in combination with a flexible disk gripped between gripping portions of the first and second disk-facing surfaces, the disk including a slit extending therethrough which, when acted upon by a fluid pressure of at least a predetermined threshold level opens to permit fluid flow between the first and second lumens and which, when acted upon by a fluid pressure less than the threshold level remains sealed preventing fluid flow between the first and second lumens and a relief well between opposing portions of the first and second housings radially outside the gripping portions, a width of the relief well exceeding a width of a radially outer portion of the flexible disk so that the radially outer portion of the disk is free to move therewithin.

The invention is directed to a one-way valve for a flexible package which comprises a first film layer having at least one first cut line and a second film layer having at least one second cut line, wherein the lines are offset from one another. An adhesive layer is disposed between the film layers. The film layers and the adhesive layer define a valve area wherein the first film layer and the second film layer are not permanently adhered to each other. The second cut line fluidly connects the interior of the flexible package to the valve area and the first cut line fluidly connects the valve area to the ambient atmosphere surrounding the flexible package. The adhesive pattern within the valve area creates a gas flow channel from the second cut line toward the first cut line.

A food pump with a safe outlet valve and an outer mounted spring comprises a pressing head (1), a primary column (2), a secondary column (3), a piston (4), a pump chamber (5), a spring (6) and a bottle locking cover (8). The pressing head (1) is installed on the primary column (2) which is arranged within the pump chamber (5). The secondary column (3) is connected to a lower end of the primary column (2). The piston (4) is sleeved on outer sides of the primary column (2) and the secondary column (3). A lock cover (9) capable of fixing the primary column (2) to the pump chamber (5) is fixed on the pump chamber (5). An outer side of an upper end of the lock cover (9) is provided with a cover flanging (91) which is turned outwards and then turned downwards to stretch. An upper end of the pump chamber (5) is inserted and fixed onto an inner side of the cover flanging (91). The lock cover (9) is provided with a locking opening (92) protruding upwards above the cover flanging (91). An outer side of the locking opening (92) is provided with an outer thread (93). An upper end of the primary column (2) is provided with a locking flanging (21) which is turned outwards and then turned downwards to stretch in order to be sleeved on the outer side of the locking opening (92). An inner side of the locking flanging (21) is provided with an inner thread (22) in threaded fit with the outer thread (93), such that a pump core composed of the primary column (2), the secondary column (3), the piston (4), the pump chamber (5), the spring (6), a glass bead (7) and the lock cover (9) can be stored and transported independently, thereby matching different pressing heads (1) and bottle locking covers (8) according to requirements, such that the use thereof is flexible.

The present disclosure relates to an enclosure of a vapor compression system, where a component is disposed within the enclosure. The component is fluidly coupled to the vapor compression system and configured to discharge a flow of fluid. The enclosure includes a hole within a portion of the enclosure and a relief valve disposed within the hole of the enclosure, where the relief valve is configured to discharge the flow of fluid in a first direction through a passage within the relief valve. The passage extends from an interior region of the enclosure to an environment external of the enclosure. The relief valve is configured to block a second flow of fluid through the passage in a second direction, where the second direction is opposite of the first direction.

A serviceable valve carousel system may include a valve carousel housing having a valve carousel receiver, a valve service port, an integrated first port adapter, and an integrated second port adapter. A rotatable valve carousel may be rotatably disposed within the valve carousel housing. The rotatable valve carousel may include a substantially cylindrical portion, a removable valve lumen, a valve cap receiver, and a removable valve cap having a substantially radiused portion compatible with a substantially radiused portion of the substantially cylindrical portion of the rotatable valve carousel. The rotatable valve carousel is rotatable between a first state that allows fluid communication through a removable valve at least partially disposed within the removable valve lumen and a second state that allows the removable valve cap and removable valve to be removed and replaced via the valve service port without use of tools while maintaining a sewage connection.

A combined paddle and pump can be used to propel a small boat. The handle telescopes with a locking nut that may be loosened to allow extension and retraction of the handle. The handle is hollow throughout and a pair of check valves are provided. One check valve opens when the handle is extended and the other opens when the handle is retracted. When one check valve is open, the other is closed. When the distal end of the paddle is placed within a volume of water or exposed to atmospheric, extension and retraction of the handle results in a fluid first being sucked into the hollow interior of the handle and then propelled out of the handle. A seal assembly prevents debris from binding tubes of the handle.

A safety valve for a housing, for releasing a housing opening of the housing if a defined burst pressure is reached or exceeded in the housing. It is provided here that in a base body of the safety valve including an elastomer, a receptacle groove that is continuous in the circumferential direction is formed for the formfitting accommodation of a retaining web of the housing. The disclosure furthermore relates to an energy accumulator for storing electric energy.

A smoking substitute apparatus comprising an air passage, a reservoir formed from an air-permeable substrate and arranged to allow air to be drawn through the reservoir, the reservoir being loaded with a source of nicotine, and one or more one-way valves arranged along the air passage and configured to allow air to flow along the air passage in an upstream to downstream direction.

A guide carriage (1) of a linear guide includes a circulation channel (8) for rolling bodies (2), which is formed from a load section (3), two deflection sections (5) and a return section (4). A valve (16) arranged in a lubricant channel (10) to prevent the back flow of lubricant from the circulation channel (8) is arranged at a supply point (13) for supplying lubricating agent to one of the deflection sections (5), and the deflection section (5) is delimited by a deflection shell (9) located in an end piece (7). The valve (16) is formed integrally with at least one of the elements deflection shell (9) and end piece (7).
