A bicycle wheel comprises a rim and a valve assembly. The rim includes a radially inner wall having an inner opening and a radially outer wall having an outer opening. A first portion of the rim includes a first securing feature (e.g., inner threads). The valve assembly is positioned in the inner opening and outer opening and includes a second securing feature (e.g., outer threads) engaging the first securing feature. The rim can include a plate that defines the first engaging feature. The valve assembly preferably includes a valve stem and a resilient bumper coupled to the valve stem and aligned with a second portion of the rim. The valve assembly can further include a seal member compressed between the valve stem and the rim. Preferably, the seal member is positioned in an annular groove in an underside of an enlarged head of the valve stem.

A valve stem structure disposed at a rim of a tire of a vehicle for connecting to an electronic tire pressure monitoring device in the tire is provided. The valve stem structure includes a tube, an air core, and a conducting wire. The tube has a first inlet, a first outlet communicating with an inner space of the tire, and a second outlet. The air core is switchably disposed at the first inlet, and a compressed air is injected into the tire via the first inlet and the first outlet by switching the air core. The conducting wire is disposed in the tube, and an end of the conducting wire extends out of the tube via the second outlet to be electrically connected to the electronic tire pressure monitoring device. A power source charges the electronic tire pressure monitoring device via the conducting wire.

An aspirator system for inflating an inflatable device includes an aspirator body and a plurality of nozzles. The aspirator body has an inner surface and an outer surface that each extend between a first end and a second end along a central longitudinal axis. The aspirator body defines a distribution channel that is disposed between the inner surface and the outer surface. The plurality of nozzles are fluidly connected to the distribution channel and extend inwardly from the inner surface towards but are spaced apart from the central longitudinal axis.

The present invention provides a tire valve stem assembly for a pneumatic tire having a valve stem for inflating the tire and having a member extending from the valve stem into an interior of the tire to prevent clogging or minimize clogging of the valve stem by leak sealing material.

A valve assembly configured for use with an inflatable product, such as a mattress, chair, pool, spa, float, or another suitable inflatable product. The valve assembly includes a first valve component that serves as an opening for inflation and/or deflation of the inflatable product, and a second valve component that serves as an opening for deflation or decompression of the inflatable product.

An air chuck includes a body and a valve core interface. The body includes output, interface, and input ports. The body defines a first passageway that extends between the output and interface ports. The input port defines a second passageway that is in fluid communication with the first passageway. The valve core interface is slidably coupled with the body and is slidable between extended and retracted positions. The valve core interface includes a shaft and a knob. The shaft includes proximal and distal ends. The distal end is at least partially disposed in the first passageway. The knob is coupled with the proximal end of the shaft. The shaft is rotatably coupled with the body and is selectively rotatable in either tightening or loosening directions via the knob. The distal end of the shaft comprises a grasping feature that is configured to grasp a valve core of a valve stem.

Embodiments provide a swimming assist garment capable of adjusting buoyancy positions. In the embodiments, the swimming assist garment includes a swimsuit, a buoyancy mechanism, and a gas regulating mechanism. The inflatable end of the gas regulating mechanism is connected to first airbags of a first buoyancy assembly and a second airbag of a second buoyancy assembly. The first bidirectional air pumps are connected to each first airbag and each third airbag of the first buoyancy assembly; and a second bidirectional air pump is connected to the second airbag and the fourth airbag of the second buoyancy assembly, to change the buoyancy positions of the swimsuit to adapt to swimming postures or to support the head on the water.

A valve assembly for controlling inflation and deflation is provided. The valve assembly includes a rapid-inflate valve having an annular body configured to couple to a valve stem port of a wheel and selectively permit gas flow into a tire. The valve has a sealing surface in a chamber with a slidable sealing member biased toward the sealing surface. In a closed position, the sealing member can be positioned in contact with the sealing surface to prohibit gas flow through the valve, and in an open position, the sealing member can be positioned away from the sealing surface to permit gas flow through the valve. Wheel can include dual valve stem ports. In this configuration, the first port has the rapid-inflate valve assembly and the second port can have a rapid-deflate valve stem, a rapid-deflate valve stem cap, a rapid-deflate to pressure set valve stem, or a standard valve stem.

An apparatus can include a first tube. The apparatus can include a manifold coupled to the first tube. The manifold can have an opening. The apparatus can include a second tube at least partially disposed in the first tube. The second tube can enter the first tube via the opening of the manifold.
