Described are valve stems for wheels or other pressure vessels that may be installed from the exterior of a wheel or pressure vessel without access to the interior, pressure retaining areas. The valve stem may include a body with a barrel and taper. A neck may be between the body and a base that includes a flange, a flange landing, and an air aperture. An air channel runs vertically through the valve stem to allow air to pass from one side of the valve stem to another with a valve core or other flow control device. The base of the valve stem may include a groove that allows the valve stem to be installed into a hole by twisting such that the groove may ride along the rim of the hole and guide the valve stem into a fully seated and sealed position.

The present disclosure generally relates to a manifold valve assembly engaged to an inflatable apparatus, such as a cushion to prevent pressure ulcers, for example. The manifold valve assembly is also in communication with a processing device to determine an optimal immersion level for a user seated on the inflatable apparatus. Additionally the processing device, in communication with the manifold valve assembly may save optimal immersion or air pressure levels for comparison to future checks of cushion pressure and send that to a user interface at the processing device. The assembly and processing device may also save and display a history of pressure checks.

A device includes a balloon inflation module having an involuted balloon housed within a lumen, an integrated reservoir in fluid communication with the involuted balloon where the balloon inflation module is configured to selectively displace a volume of fluid from the integrated reservoir into the involuted balloon and from the involuted balloon into the integrated reservoir. The device also includes a port configured to receive an accessory module. In one embodiment, the accessory module is a communication module having a logic circuit coupled to an ambient microphone configured to pick up ambient audio content, an ear canal microphone configured to pick up audio in the proximity of an ear canal, and an ear canal receiver configured to provide audio content in the proximity of the ear canal. In some embodiments, the integrated reservoir is formed within portions of a push button spring-loaded pump assembly. Other embodiments are disclosed.

A system includes a client application executed by a client computing device for setting up an inflation level and checking an inflation level of an inflatable cushion having at least one air cell or zone and at least one pressure sensor within the cushion that detects air pressure. The client computing device communicates with the inflatable cushion and determines an optimal inflation level for a user of the inflatable cushion.

Disclosed is a basement sewer drain pump housing that draws fluid from a drain into a housing, where after the fluid is discharged from the housing and out of the basement. The device comprises a pickup tube having a fluid level sensor, which is placed within a sewer main drain or floor drain. The housing comprises an enclosed volume, a suction tube connected to the pickup tube, a suction pump, and a discharge pump. The pump is activated by a switch controlled by the pickup tube fluid sensor, the fluid is drawn into the housing from the drain and discharged through a discharge pipe. The device operates from outlet or battery and serves as a basement drain pump that prevents fluid and sewage backflow during power outages and plumbing blockages. Another modification provides two donuts to prevent the flow of fluid locking both the floor drain and the main sewer drain. Another embodiment show an inflator to stop the flow of fluids.

Various embodiments of the present disclosure provide a reusable valve in which a seal portion is co-molded with and overmolded to the valve stem to provide a secure mechanical bond therebetween. In one embodiment, the valve includes a snap fit between the valve stem and a retaining cap to provide easy assembly of the valve as well as an efficient and compact retention mechanism for a biasing spring and the valve stem in relation to the valve housing. In one embodiment, the valve includes an easy-to-use opening and closing mechanism that provides tactile feedback to the user when moving the valve stem to an open position and to a closed position to inflate, deflate, or maintain air or gas pressure in the inflatable article. The present disclosure also provides a dunnage bag with such valve.

A valve stem assembly for a tire includes a removable grommet of a plurality of grommets having different shapes and sizes. The removable grommets allow the valve stem assembly to be used on a variety of rims. Each grommet fits into distinct holes within the rims. The valve stem assembly also includes a valve stem body that receives the removable grommets and an attachment end that encloses a valve core within the valve stem body. A cap may cover the valve core and attachment end.

An apparatus and method for mounting and inflating tires is described that is suitable for quickly sealing the beads of a tire to the rim of a wheel. The present invention delivers a high volume of pressurized air to an interior of a tire through a nozzle. The apparatus of the invention is particularly well suited for tire changing machines and tire mounting subsystems. The apparatus includes a tire changing station, an air supply controller, and a nozzle capable of delivering a high volume of pressurized fluid into an interior of a tire through a valve stem hole of the wheel rim.

The present application relates to an apparatus of joined valves used to test and maintain refrigeration systems. More particularly, the present application provides a Multiple Valve Refrigerant Leak Protection Device having a specifically preferred embodiment including a ball valve with a soldered pipe connection, as part of the fitting with a Schrader valve, primarily used for the maintenance and transfer of refrigerant from commercial refrigeration equipment. Schrader valves are most commonly used in this application with a ball valve. A ball valve would be the preferred valve, but a wide range of valves could be used. The resulting valves can be used to test and maintain refrigeration systems, and act to prevent leakage where refrigeration fluids are often released to the atmosphere when the system is being maintained or repaired.

A valve positioning structure is provided for pressing down a switch arranged in a valve so that fluid is allowed to flow through an inlet opening of the valve when the switch is pressed down in order to control the fluid to flow into/out of at least one bladder. The valve positioning structure includes a casing that receives the valve therein and the casing is provided with a contact member and a manipulation member respectively and movably on upper and lower surfaces of the casing. The contact member and the manipulation member are coupled to each other so that the contact member is operable to drive the manipulation member to move. The manipulation member includes an operation section, where the operation section is movable toward and is enabled to press down the switch when the manipulation member is driven by the contact member to move toward the switch.
