A puncture repair liquid holding container formed from a container main body provided with a holding portion and opening portion, and a cap attached to the opening portion, includes: a first flow channel for the cap to introduce compressed air from outside the container, where the first flow channel is configured from a straight portion and branched portion, a closing plug having a shape that blocks the straight portion is slidably inserted in the straight portion, and switching is possible between a closed condition where the closing plug is positioned above the branched portion or closer to an opening end side of the straight portion than the branched portion such that the first flow channel is closed, and an opened portion where the closing plug is positioned more to a closing end side of the straight portion than the branched portion such that the first flow channel is opened.

A wheeled tire includes a tire, and a wheel disposed on the tire. A space between the tire and the wheel is filled with a filler gas. The filler gas includes nitrogen gas having a concentration equal to or greater than a concentration of nitrogen gas in air, and hydrogen gas having a concentration of 0.5% or more. A concentration of oxygen gas in the filler gas is less than a concentration of oxygen gas in air.

The application discloses a plastic air pump mechanism, which comprises a plastic body, a plastic output unit and an actuating unit; the plastic body has an integrally forming structure, which comprises a plastic cylinder and a plastic bracket disposed at an air inlet end of the plastic cylinder; the plastic output unit is detachably connected to an air outlet end of the plastic cylinder; the actuating unit comprises a motor, plastic gears disposed on the plastic bracket and electrically connected to the motor, and a plastic rocker arm driven by the plastic gears to realize reciprocating of a piston in the plastic cylinder; and a large body insert of metal is provided in an air outlet of the plastic cylinder. The plastic air pump mechanism can reduce product weight, simplify production and installation processes, save materials and labor costs, and reduce self weight of a vehicle.

An inflation machine configured to inflate an item. The inflation machine includes: (i) an air pump; (ii) a first air dispenser having a first hose and a first air chuck, where the first air dispenser is an analog dispenser and is in communication with the air pump; (iii) a second air dispenser having a second hose and a second air chuck, where the second air dispenser is a digital dispenser and is in communication with the air pump; and (iv) a controller configured to activate the first air dispenser or the second air dispenser in response to a user input.

An apparatus and method to equalize the pressure in multiple tires supported by a single axle or strut of an airplane is shown. A control block connects the pressurized gas to a distribution block and meter. From the distribution block high pressure lines and no-loss chuck valves connect the pressurized gas to the multiple tires. Steps to be followed as programmed in the meter include startup, testing, calibration, setup and finalize. A permanent record of the steps in equalizing tire pressures is maintained.

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.
