A versatile air-valve connecting device includes two valve connectors and a rotator. The two valve connectors each have an air inlet. The rotator has a cam including a major diameter and a minor diameter and has an air hole. The rotator normally contacts the two valve connectors with the minor diameter so that the two valve connectors are in a relaxed state, and when the rotator is rotated to have the major diameter contacting the two valve connectors, the two valve connectors are slightly deformed under compression and turned into a use state for connecting a valve, where the air hole is communicated with the air inlet of one of the valve connector while the air inlet of the other valve connector is closed by the cam portion into airtightness.

Systems and methods for accommodating gravity based devices within wheel rims. An exemplary method includes identifying a number of the gravity based devices to be contained within the wheel, identifying a type of each of the gravity based devices to be contained within the wheel, identifying, based on the type and the number of the gravity based devices, a location where each of the gravity based devices are to be installed within the wheel (i.e., the air hole locations), and generating holes in the rim, where the number of the holes equals the number of the gravity based devices, and where for each air hole location in the air hole locations a single hole in the holes is generated

A tire inflation system and method for a tire supported by a wheel, the tire inflation system including a pump system including a pump cavity configured to fluidly connect to the tire, an actuating element configured to actuate relative the pump cavity, a drive mechanism rotatably coupled to the wheel, the drive mechanism including a motion transformer and an eccentric mass, a valve fluidly connecting the pump cavity to a fluid reservoir; and a control system configured to operate the valve.

An air valve connector includes a head and a switching assembly. The head has a first insertion hole, a second insertion hole, a communicating passage, and an inlet hole. The first insertion hole is provided with a first airtight portion disposed between the communicating passage and the inlet hole, and a second airtight portion disposed between the inlet hole and the first port. The switching assembly includes a plunger movably disposed in the first insertion hole to alternately abut against the first airtight portion or the second airtight portion.

A vehicular tire air pump system designed for public use at gas stations and along highways is disclosed. The system features a durable, weather-resistant body anchored to the ground, and is equipped with a pump compressor for generating and autonomously regulating compressed air based on user-defined pressure thresholds displayed on a digital touch screen. The air hose of the system includes a non-flexible (i.e., rigid) and elongated portion that can be held by a user in a standing position and has a threaded female adaptor for secure, ergonomic connection to tire valves, enabling inflation from a standing position. The system integrates a multifunctional LED for status indication, a payment module accepting coins, cash, and cards, and a speaker for multilingual operational voice alerts. In some embodiments, the system has an NFC camera for tire health assessment and automatic car model recognition and a location tracker.

In order to solve the problem of discrepancies between inflation pressure and actual tire pressure during the tire inflation process, the present invention discloses a correction method and an inflator that implements this method. This significantly reduces the error between the pressure displayed on the gauge and the actual tire pressure, thereby enabling the functionality for automatic inflation and cessation of inflation for the tire.

A device for preventing excessive increase of an internal pressure of a rolling assembly, the rolling assembly having a rotation axis and comprising a wheel and a tire, the tire being mounted onto the wheel creating an inner cavity surrounded by a wheel internal surface and a tire internal surface, comprises a cold spot placed in the inner cavity of the rolling assembly for condensing vapor contained in a gas filled in the inner cavity.
