A check joint structure for a connection of an air nozzle of a tire and a connection hose of an air compressor, the air compressor contains: a box, a sealant supply can, and a connection hose. The box includes a body of the air compressor. The sealant supply can includes an open segment and a supply tube. The connection hose includes a first segment and a second segment. The second segment has a check connector which includes a fitting sleeve, and the fitting sleeve has a threaded orifice, a through orifice, and a projected shoulder. A cylindrical base includes a cylindrical room, a stepped coupling segment, a conduit, and a first stepped portion. A first spring is received into the cylindrical room to abut against the first stepped portion. A valve bolt includes a contacting element, at least one cutout, a head, a conical rib, and a neck.

A wheel-mounted air compression apparatus for maintaining a predetermined inflation pressure of a tire mounted on a wheel of a vehicle and the tire having an inflation port includes a housing defining an air compression chamber and has an air compressor device positioned therein. The apparatus includes a plurality of support legs spaced apart from one another. Each support leg is attached to the housing and extends away therefrom and may include a pair of sleeves that are length-adjustable for mounting to wheels of various sizes. A pressure sensor is situated in the housing and operably connected to the air compressor and to a nozzle for determining a current pressure of air within the tire. A controller or other electronics cause the air compressor to pump air into a tire if the air pressure therein is detected as declining below a predetermined amount.

An inflation manifold connected to dual pneumatic tires by air hoses provides a central location for tire inflation and location of pressure sensors. A hose block connected to dual pneumatic tires by air hoses provides a central location for location of pressure sensors. The pressure sensors may be TPMS sensors or a combination of TPMS sensor and pressure gauge.

A wheel inflation apparatus including a wheel engagement unit that suspends a tire/wheel assembly and at least one inflation unit coupled to the robotic arm, each inflation unit being configured to inflate the tire/wheel assembly. A load measuring unit is configured to sense an amount of load being applied to the wheel/tire assembly. A controller is coupled to the load measuring unit for receiving a load signal and determining an internal air pressure of the tire/wheel assembly based on the load signal. The controller controls the at least one inflation unit based on the determined internal air pressure and a target (desired) air pressure value.

A pump head configured to secure various air valve types is disclosed. The pump head may include a housing and an interior unit sized and shaped to receive a valve head. A moveable pin disposed within the housing coaxially with the first axis may define a pin notch disposed about an exterior circumference of the moveable pin. A first taper unit may be disposed in the housing coaxially with the first axis and coupled to the pin return spring. A second taper unit may be disposed in the housing coaxially with the first axis and adjacent to the first taper unit. An elastic taper C-ring may be disposed between the first and second taper units. The second taper unit is moveable towards the first taper unit, thereby compressing the elastic taper C-ring circumferentially in at least one of two positions, the elastic taper C-ring compressed about the pin notch in the first position and about the valve head in the second position.

A pumping assembly keeps a pneumatic tire from becoming underinflated. The pumping assembly includes an even number of pumps attached to the tire rim, a gravity mass for producing a pumping action, a cam fixed to the gravity mass for maintaining the cam in a fixed position relative to the gravity mass, and rollers for engaging the cam and producing the pumping action as the tire rim rotates and the gravity mass retards rotation of the cam as the tire rim rotates.

A cap unit for puncture repair comprises a check valve 6 for preventing a backflow of a puncture repair liquid supplied from a bottle container 2. The check valve 6 is disposed in a first flow path 3 used for taking compressed air from a compressor 8 into a bottle container 2. The check valve is formed by a ball valve 21 disposed in a valve housing zone Y which is located in a vertical passage part 15 of the first flow path 3 and between an upper opening 3U and a valve seat portion 20. The ball valve 21 is formed by a rubber-like elastic body having a specific gravity of 1.1 or more, and a rebound resilience of 15% or less.

A device for dispensing pressurized air and/or tire sealant from a pressurized can. The device comprising a cap body, a depressor button with a lock clip, and a hose positioned within the cap body attached to the pressurized can. The lock clip locks the depressor button in the compressed position for ease during use, while a shield element keeps the depressor button in the non-compressed position for safety during non-use. The hose provides an extension to attach to a tire stem valve, while being stored and attached to the cap body of the device.
