A valve-coupler system has a lever that extends under a length axis of the valve body to enable one-handed operation. The valve-coupler body has an opening that is configured over a valve stem and a seal actuator having a lever that can be rotated about a pivot with a single hand to create a seal around the valve stem. Additionally, a valve-coupler may have a gas inlet valve that can be activated by the same single hand to open the valve and allow gas to flow into the valve stem. The inlet valve may be configured in line with the lever whereby the inlet valve is opened when the lever is rotated about the pivot to contact the inlet valve. The inlet valve may be configured on the valve body for manipulation by a user's finger or thumb. The inlet valve may be on the top of the valve body.

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.

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. A lock arm may be configured to engage the first taper unit with the second taper unit, thereby compressing the elastic taper C-ring circumferentially in one of at least 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.

An air compressor contains: a box in which the air compressor and a sealant supply device are accommodated. The air compressor is configured to produce high-pressure airs, and the sealant supply device has an air inlet pipe and a supply pipe. An air outlet pipe of the air compressor is connected with the air inlet pipe, and the air compressor is detachable from the sealant supply device. The air inlet pipe is configured to receive the high-pressure airs from the air compressor, the supply pipe is configured to output chemical sealant from the sealant supply device, and a tube is configured to communicate the air inlet pipe with the supply pipe. A rotation element includes a driven portion and a central stem. The rotation element is fitted on the second sub-tube. The central stem of the rotation element abuts against a top of the tube.

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.

The invention is directed to a device for inflating a tire that includes a housing with at least one first connection port and at least one second connection port. The second connection port includes connecting means to interconnect the device with a pressure tank. The first connection port is fluidically connected to the second connection port by means of a fluid passage. Furthermore the device comprises a first valve. When a pressure tank is connected to the second connection port and when the first valve is in a closed state, the first valve is suited to prevent air from flowing from inside of the pressure tank out of the first connection port. When the first valve is in an open state, it is suited to allow passage of air from inside of the pressure tank through the fluid passage to the first connection port. The device further includes a second valve that is connectable to an inflator for pressurizing the tank.
