An automatic tire inflator assembly includes an input hose that is fluidly attachable to an air source to receive compressed air from the air source. An output hose is fluidly attachable to an air stem of an inflatable tire. A control unit is fluidly coupled to the input hose to receive the compressed air from the air source. Additionally, the control unit is fluidly coupled to the output hose to inflate the inflatable tire. A gauge is fluidly coupled to the control unit and the gauge is settable to determine the pre-determined threshold pressure. The control unit is turned off when the gauge measures air pressure that exceeds the pre-determined threshold pressure to inflate the inflatable tire to a desired air pressure.

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.

The present invention is an apparatus for tire inflation designed to allow users to properly inflate, maintain, and monitor the condition of vehicle tires. The tire inflation device of present invention is comprising of: a carrying case having a housing, a lid attached to the housing using a hinge, a plurality of locking latches to lock the lid over the housing and a handle configured over the lid to allow easy transport of the tire inflating device. The tire inflation device further comprises, a control head assembly to control the working of the device, an air compressor coupled with the control head assembly to provide compressed air for inflation of tires, a hose assembly to connect the device with the vehicle tires and a plurality of power adapters to connect the device with the power source. The control head assembly of the inflation device is further comprising of, a program control module, an auto level manifold, a plurality of output modules, an air release valve, a pressure release valve, a plurality of buttons and switches, and a display unit.

A method of inflating a vehicle tire, having an internal volume between about 10 gallons and about 12 gallons, includes discharging compressed air into the internal volume with an inflator. The inflator has an inflator housing, a motor within the inflator housing defining a motor axis and including an output shaft rotatable about the motor axis, a DC power source configured to provide power to the motor at a nominal output voltage, and a pump within the inflator housing and coupled to the output shaft. The pump includes a cylinder defining a cylinder axis and a piston that is reciprocable within the cylinder along the cylinder axis in response to rotation of the output shaft. By discharging compressed air into the internal volume, increasing a static pressure of the internal volume by 5 pounds per square inch (psi) from a starting pressure in the internal volume between 28 psi and 31 psi occurs within 40 to 60 seconds.

A diagnostic system and method for troubleshooting an electronic system of a vehicle includes receiving a diagnostic trouble code set into a diagnostic system. The diagnostic trouble code set includes one or more diagnostic trouble codes. The method includes receiving diagnostic specifications. The diagnostic specifications associate connector pins and wires of the electronic system with possible diagnostic trouble codes. The method includes receiving wiring circuit specifications. The wiring circuit specifications associate wiring circuits of the electronic system with the connectors of the electronic system. The method includes determining a set of possible repair locations based on the diagnostic trouble code set, the diagnostic specifications, and the wiring circuit specifications, and displaying at least one possible repair location of the set of possible repair locations.

An automatic pressure detection device of an inflation machine includes an inflation machine and an inflation control module. A first connector of a connection pipe connected to the inflation machine is connected in sequence to a first hose line and a nozzle in order to charge gas into an object-to-be-inflated (such as a tire) for inflation. A second connector of the connection pipe connected to the inflation machine is connected in sequence to a valve core passage element of the inflation control module, a regulation and control valve, and a pressure transducer, and the pressure transducer is electrically connected to a circuit board. The valve core passage element and the nozzle are arranged to have the same flow so that the inflation control module may simulate a flow of gas charged into an object-to-be-inflated.

A method of inflating a tire of a vehicle includes connecting the vehicle to an external air pump, using a connection, to provide communication of information between the vehicle and the external air pump. The method also includes transmitting information from the vehicle to the external air pump over the connection and controlling the external air pump based upon the communicated information to provide air to a vehicle tire, connected to the air pump, until the communicated information indicates that the tire has reached a desired pressure level, at which point the air pump ceases provision of air to the vehicle tire.

A portable inflation device having a pump, a control device, a user interface, and an inflation indicator. The pump includes an elongated hose with an inflation nozzle. The control device controls operation of the pump and is configured to sense a current pressure of an object, calculate the estimated remaining time to inflate the object to a target pressure, and display the remaining time using the inflation indicator. The user interface is configured to allow a user to enter the target pressure into the control device.
