An inflator includes an inflator housing, a pressure sensor operable to generate a pressure signal related to an outlet pressure of the inflator, a motor within the inflator housing, a battery pack removably coupleable to the inflator housing, and a controller electrically coupled to the motor and the battery pack. The controller is configured to receive the pressure signal from the pressure sensor, determine a rate of pressurization change based on the pressure signal, determine a static pressure value based on the rate of pressurization change, and determine a motor time delay based on a target pressure value, the static pressure value, and the rate of pressurization change. The controller is also configured to generate a control signal when the motor time delay substantially equals zero. The control signal is operable to cause power to the motor to be turned off to stop a pressurization condition of the inflator.

A repair system for a vehicle includes a base and a lift component movably secured to the base for lifting a portion of a frame of the vehicle. An air compressor unit is disposed on the base and has a discharge hose configured to be selectively connected to the tire for delivering compressed. A sealant reservoir is disposed on the base and filled with a flat tire sealant. The discharge hose is optionally configured to deliver the flat tire sealant to the tire. A controller is disposed on the base and receives tire data from the vehicle and controls discharge of the compressed air from the air compressor unit to the tire and optionally controls discharge of the flat tire sealant to the tire based on the tire data. The tire data includes a tire pressure reading associated with the tire.

An anti-jet joint structure of a connection hose of a vehicle air compressor contains: an accommodation box, an adhesive supply can, and a connection hose. The accommodation box accommodates the vehicle air compressor started by a power to produce air. The adhesive supply can accommodates chemical adhesive for repairing a tire, and the adhesive supply can includes an open segment and a supply hose. The connection hose includes a first joint and a second joint opposite to the first joint. The first joint is engaged with the supply hose, and the second joint is screwed with a gas nozzle of the tire. The second joint is the anti-jet joint structure and has a first connection assembly and a second assembly. The first connection assembly is connected with or is removed from the second connection assembly having different interior structures and volumes so as to mate with various tires.

An air pressure maintenance apparatus and method uses one or more high-pressure gas storage tanks coupled to an inflation hose via a calibrated rigid measurement chamber and automated system of valves to permit rapid inflation of a tire or other inflatable device to an accurate target pressure accounting for temperature effects, and recording accurate pre- and post-inflation pressure for analysis of deflation over time.

A control system for an air maintenance tire system is provided. The control system includes a sensor unit that in turn includes a pressure sensor for measuring a pressure in the tire cavity and an antenna for transmitting pressure data. A processor receives the pressure data and includes a memory for storing a predetermined low-pressure threshold. Actuation means that are in communication with the processor and actuate and de-actuate operation of the air maintenance tire system. A first signal is transmitted from the processor to the actuation means to actuate operation of the air maintenance tire system when the measured pressure in the tire cavity is below the threshold. A second signal is transmitted from the processor to the actuation means to de-actuate operation of the air maintenance tire system when the measured pressure in the tire cavity is at or above the threshold.
