An apparatus for dispensing pressurized air and/or tire sealant from a pressurized can. The apparatus comprising a nozzle and a locking element for the nozzle and/or a cap including a free length of hose that is positioned within the cap. The locking element locks the nozzle in the non-dispensing position for safety during non-use or in a dispensing position for ease of use. The hose provides an extension for the nozzle for hard to reach places, and stores fully wound within the cap, such as along the inner circumference of the cap.

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.

An apparatus for transferring air from one vessel to another vessel that includes a hose of predetermined diameter and length having a first end and a second end; a first device attached to the first end of the hose for removing air or other gas from a first vessel; and a second device attached to the second end of the hose for dispensing the air or other gas from the first vessel into a second vessel or out of the second end of the hose.

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.

A system for regulating pressure in one or more vessels by adapting a fluid input to receive a fluid from a fluid source such as an air compressor at a constant pressure. At least one fluid outlet assembly is used to attach the system to a vessel such as a bike tire, ball, or car tire. At least one controllable valve is used to couple the fluid outlet assembly to the fluid input, the valve is controllable to pulsate air going through it, check the new pressure in the vessel, and either continue to increase pressure in the vessel, decrease pressure, or stop inflating. A pressure sensor corresponding to a fluid outlet assembly adaptable to provide pressure values from each vessel to a controller. The controller receives at least one desired pressure input, compares that value to the pressure value from the at least one pressure sensor, and selectively energizes the controllable valve to adjust the pressure in the corresponding vessel until the pressure within the vessel is equal to the desired pressure.

Methods of reducing oxygen in tire air chambers are disclosed herein. Compositions for reducing oxygen in tire air chambers are disclosed herein. Wheel assemblies including compositions for reducing oxygen in tire air chambers are disclosed herein.

An inflator includes a body having a first passage, a second passage, and a third passage. The first passage is configured to couple with an air tank or a compressed gas cartridge. The first passage unidirectionally intercommunicates with the second passage and the third passage. The second passage is configured to couple with an air pump. The third passage is configured to couple with a to-be-inflated-object. A first one-way valve unit is disposed between the first and second passages, such that compressed gas is only flowable from the second passage to the first passage. A second one-way valve unit is disposed between the first passage and the third passage, such that compressed gas is only selectively flowable from the first passage to the third passage.

A valve assembly for a tire pressure management system includes a housing having a first perforation and a second perforation. The first perforation is selectively in fluid communication with the second perforation. A shuttle assembly is provided in the housing. A failsafe piston is connected to the shuttle assembly. A first biasing member applies a bias to the failsafe piston. A second biasing member applies a bias to the shuttle assembly. When a pressure differential between a pressure in the second perforation and a pressure in the first perforation is at or below a predetermined value, the bias applied by the first biasing member urges the failsafe piston toward the shuttle assembly to prevent fluid communication between the first perforation and the second perforation.
