  • Patent number: 9310228
    Abstract: A compressed air indicator includes a housing having a pair of fittings and at least one (1) external pressure status window. The housing allows an “in-line” connection to an air line allowing compressed air to pass through. Once connected, movable indicator sleeves within the housing are visible through any window. The indicator sleeves are acted upon and correspondingly positioned relative to each window based upon “pressure” or “no-pressure” conditions within the air line and the housing.

The regulator includes a body, a two-position valve within the body, and a rotational lock. The body includes an air inlet, an air outlet, and an air vent. In one position, the valve directs air from the air inlet to the air outlet when the tire pressure is below a preset level; and, in a second position, the valve directs air from the air inlet to the air vent when the tire pressure exceeds the preset level to prevent overfilling. The valve moves rapidly between the two positions, and is unstable between the two positions. The valve includes a regulator enabling the preset level to be adjusted. The rotational lock enables the regulator to be screwed onto a tire stem, but prevents removal of the regulator from the tire stem without a key.

  • Patent number: 8196615
    Abstract: A device and method of using a liquid/air pressure testing tool to assist in testing and repairing liquid-filled agricultural tires is herein disclosed. The device provides a valving arrangement to allow alternating fluid transfer and air backfilling of a fluid-filled agricultural tire. The device utilizes quick-disconnect fittings providing quick in-line installation therebetween a fluid pump and a fluid filled tire. The device provides an inline ball valve and an isolation valve, thereby providing isolation of a pumping source and an air back-filling means, respectively. During fluid filling of a tire, the isolation valve allows monitoring of internal tire pressure using a common pressure gauge without removing the device or disconnecting any attached hoses. The device thus eliminates repeated steps when testing or repairing large fluid-filled tires as used on farm tractors and other agricultural machinery.

    Abstract: An air inflation device is a pass-thru vehicle tire inflation device. It ensures exact air pressure without the use of an air gauge. It works by attaching to a tire valve, and then to an existing air supply, such as those found at gas stations, and utilizing an internal pressure relief valve that is pre-set to exact PSI recommendations. This means that the inflation device will put only the amount of air needed in every tire without having to use a pressure gauge. Air moves through an internal air chamber constructed of plastic or rubber tubes that runs through the nozzle to the head that attaches to the valve of the tire. A plastic valve located on the back of the apparatus connects to any existing air supply. A pressure relief valve is integrated into the bottom of the nozzle that ensures that the exact PSI recommendations are maintained.

  • Patent number: 6668879
    Abstract: An inflatable bladder is provided with an inflation valve device that includes a sleeve member, a tubular indicator mounted movably in the sleeve member and marked with indicia for indicating internal pressure of the bladder, an inflation needle mounted in the indicator for inflation of the bladder, and an urging member disposed between the sleeve member and the indicator in such a manner that outward movement of the indicator resulting from the pressure difference between the pressure in the bladder and the atmospheric pressure results in displacement of the urging member, which is indicated by the indicia exposed from the bladder.

  • Patent number: 6561212
    Abstract: An apparatus mounted on a valve for indicating a pressure of tire comprising a pressure indicator formed of transparent plastic and including a base having a scale, base consisting of an inner hollow cylinder sleeved on valve and an outer hollow cylinder with tops of cylinders open, a spring put on inner hollow cylinder, a seal put on inner hollow cylinder being urged by spring for eliminating a potential air flow through an inner or outer periphery of seal, and a cap having a downward peg engaged with valve, cap being releasably secured to a top of base. In indicating pressure of tire, air is flowed from within tire to push down seal through valve and pressure indicator so that a top of seal is aligned with one of marks of scale. Further, pressure indicator is disengaged from valve prior to inflating tire.

  • Publication number: 20020157707
    Abstract: There is a valve assembly for controlling the admission of a fluid such as air into a vehicle tyre or other pressure vessel. The assembly includes a housing (1) with a valve assembly (10) movable therein by a predetermined pressure in said vessel against a spring 5A. The valve member (10) is movable from a first position at which ports (14) of an inlet passage (13) in the housing (1) are open to fluid flow into the vessel to a second position at which the ports (14) are closed by the valve member (10). In use of the valve assembly when the valve member (10) is biased to the first position by the spring 5A the fluid can flow into the vessel until pressure therein reaches the predetermined pressure and the valve member (10) is moved to the second position to terminate flow into the vessel. The valve assembly also includes a low pressure indicating means comprising a transparent cap 3A with an opaque band (23) and a collar (8) movable with the valve member (10).

  • Patent number: 6357469
    Abstract: A vehicle wheel includes a tire that is sealed to a rim. The tire is inflated with air to a desired pressure level via a valve assembly. The valve assembly includes a valve stem with an elongated body having a central bore extending longitudinally through the body. A pressure sensor is mounted within the bore to measure the air pressure within the tire. A ball and plunger valve member is engagable and disengagable with a valve seat formed within the bore. A central tire inflation system uses the pressure sensor to monitor the tire pressure for each wheel on the vehicle. When the pressure sensor measures an air pressure in the tire that is below a desired level the central tire inflation system inflates the tire with air until the desired pressure is achieved.

  • Patent number: 6293297
    Abstract: A tire pressure indicator is mounted onto the fill stem of a tire and provides a window for indicating if the tire has adequate pressure or not. The indicator show adequate, marginal and underinflated conditions by color bands opposite the window. The pressure indicator may be permanently mounted onto the tire and used to fill the tire and maintain pressure in the tire. As the tire is filled the indicator moves from one color band to the next until the indicator shows that adequate pressure has been attained whereupon the hose may be disconnected.

  • Patent number: 6167900
    Abstract: A tire valve stem having an integral pair of O-rings over which a pressure gauge or other device can be mounted by sliding a mating collar provided on the device over the O-rings. The O-rings provide an air-tight seal against the collar, and allow the device to rotate relative to the stem, either during or after mounting, to position the device anywhere within a 360° arc around the stem. The O-rings are located on either side of an orifice which extends through the valve stem, beneath the valve. Air passes from the pressurized valve stem, through the orifice, into an air-tight region between the O-rings, valve stem and collar. A port in the collar allows air to pass through the collar from the air-tight region into the device.
