A pneumatic element including: a first, a second, and a third air chamber which are coupled to one another, the first air chamber being coupled to the second air chamber by a weld joint and the second air chamber being coupled to the third air chamber by another weld joint; and an overflow area, which is arranged within the weld joints along a longitudinal axis of the pneumatic element, for a pneumatic communication between the air chambers. Each of the air chambers has a first state in which a pressure inside the air chambers corresponds to a pressure outside of the air chambers and a second state in which the pressure inside the air chambers is greater than the pressure outside of the air chambers. Furthermore, a flow opening is provided for a pneumatic communication between the overflow region and the second air chamber in the first state.

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.

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 for air chambers includes a fixed body and a mobile selector body, wherein the mobile selector body is disposed coaxially in the fixed body. The mobile selector body is configured to slide with respect to the fixed body. The mobile selector body has a first position of use, associated during use to at least a first outlet, and a second position of use, associated during use to at least a second outlet.

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 adjusting device for a vehicle component comprises at least one inflatable chamber and a pump configured to supply fluid to the at least one inflatable chamber. The pump comprises a housing, a first output port provided on the housing and a second output port provided on the housing. At least one of the first and second output ports has an integrated check valve disposed at the respective output port. The integrated check valve is configured to receive fluid discharged from a pump chamber and is in direct fluid communication with the respective output port. The integrated check valve is arranged within the housing.

A valve unit (1) with a single-piece valve body (4) includes a cylindrical collar (5), a valve seat (7), a main duct (9) and an auxiliary duct (10). The cylindrical collar (5) projects from a reference plane (12) obtained in the valve body (4) and is configured so that it can be arranged against a rim (2) when the cylindrical collar (5) is inserted in a hole (6). The cylindrical collar (5) has an end (5a) configured so that it can be deformed and can define a flared portion (13) of the main duct (9) which interferes with the rim (2) at the level of the hole (6) thus providing a mechanism (11) for fixing the valve unit (1) to the rim (2).

At least one exemplary embodiment is directed to earpiece devices that share information with other earpiece devices within range (e.g., GPS location and identity). For example multiple users can send signals to each individual earpiece when in range or to a mobile audio communications device via a wireless connection with each earpiece.
