Embodiments of the present disclosure provide systems and methods for an air valve and an air valve adapter. The air valve may comprise a base, a top attached to the base via a hinge, a tab connected to the top, and a gripping shape disposed at an end of the tab, wherein the gripping shape is disposed within a well of the base. The base may be attached to an inflatable apparatus via a weld or an adhesive. The air valve adapter may comprise an inserting end, a hollow end, a gripping section between the inserting end and the hollow end, and an aperture in the gripping section, wherein air may supplied in the inserting end to travel to the hollow end.

In an aspect, an inflatable object includes an object body enclosing a chamber to receive air, and a valve mounted to the inflatable object body, including a valve body defining a passageway between the chamber and an ambient environment. The valve body has a shoulder. The valve body defines an outside end, which opens to the ambient environment, and an inside end, which opens into the chamber. The valve includes a one-way flap that is movable between an open position to permit fluid communication between the chamber and the ambient environment through the passageway, and a closed position. The one-way flap is biased to the closed position with a closing force selected to be overcomable to move the one-way flap to the open position by an airflow having a speed that is less than about 48 m/s, and which is at a pressure lower than 1 atmosphere.

An inflating device includes an air pump, a valve engaging head, and a pushing apparatus disposed on the air pump and selectively engaging and disengaging the valve engaging head. The valve engaging head includes a main body, a connection assembly coupled to the main body and having a connection hole for a Presta valve and another connection hole for a Schrader valve, and a valve seat movably disposed in the main body. The connection assembly has a receiving hole and the valve seat is movably disposed in the receiving hole. The pushing apparatus selectively contacts and disengages from the connection assembly. The pushing apparatus has a pushing portion adapted to drive the valve seat. The pushing apparatus engaging the valve engaging head includes the pushing portion pushing the first abutting portion, thereby driving the valve seat toward the second connection hole.

An adjustable multiple bladder system for an article of footwear is disclosed. The bladder system includes an outer bladder that may be inflated using an external pump. A valve member is disposed within the outer bladder and divides the outer bladder into two distinct inflation chambers. The inflation chambers may be inflated separately.

A pressure relief valve may comprise a housing, a disk, and a seal. The disk may be configured to deflect relative to the housing. The seal may form a sealing interface with at least one of the housing or disk. The pressure relief valve may be coupled to an inflatable slide or an aspirator.

A safety valve stem cap includes a valve tool that can be used for removing the valve stem and quickly deflating the tube for travel or storage. The valve stem cap has a frustoconical-shaped body with a circular bottom edge and a flat upper surface. The valve tool extends within a recess defined within the cap body. The valve tool includes a planar floor and two upright prongs extending from the floor. In an embodiment, the floor of the valve tool is integrally connected with the cap body. In an embodiment, the valve tool includes a hollow body mounted within the recess. The planar floor and upright prongs extend within the hollow body.

A tire inflation valve having anti-rotation features has an external valve seat, and includes a valve body, a valve stem extending through the length of the valve body, and anti-rotation features disposed interior to the valve body. The valve stem is configured to move relative to the valve body, such that a resilient seating surface disposed at a proximal end of the valve stem is displaced relative to a valve seat formed by an exterior surface of a proximal end of the valve body. The anti-rotation features may include a complementary slot and protrusion, a keyway and complementary protruding ridge, and/or complementary channels and lateral protrusions.

An electropneumatic switch arrangement having an actuation device plurality of pneumatic outlets for connection to fluid-fillable devices, and a pneumatic supply connection for connection to a pressure source, the actuation device being connected to a sealing device, the actuation device being designed in such a way that, when it is actuated, it opens a predefined flow path between the supply connection and at least one of the outlets and, in doing so, closes a current path for actuating the pressure source, characterized in that the sealing device is mechanically coupled to the actuation device in such a way that at least a part of the sealing device is moved, in particular displaced, by the actuation device when this is actuated, thereby opening a flow path between the supply connection and at least one of the outlets.
