Abstract:
An improved injector apparatus for introducing flowable force compensating material into a tire/wheel assembly for the purpose of equalizing radial and lateral force variations of the tire/wheel assembly when in use on a vehicle. The injector apparatus generally comprises a container having a cylindrical side wall, an inlet end cap and an outlet end cap, which together enclose a chamber for flowable force compensating material, and a flexible hose having a quick disconnect coupling at its discharge end for conveying a mixture of pressurized air and flowable force compensating material from the chamber to the interior of a tire/wheel assembly. The outlet end cap comprises at least one channel groove, which helps direct the flowable force compensating material toward an outlet fitting in a manner preventing the flowable force compensating material from getting trapped in the cylinder.
Abstract:
A repair device and method comprising a canister having an internal cavity, an input connecting valve, an output connecting valve, and an output hose for purposes of inflating a pneumatic device such as a flat tire. The utility of this device is as a readily available bridge to connect a deflated tire with any available air source such as an inflated tire. A sealing mixture may be stored in the internal cavity of the canister for injection into a leaking or flat tire to effect repairs by sealing any leaks. When attached between an inflated tire and a flat tire, the sealing mixture is injected into the flat tire by the pressure of the inflated tire and the flat tire may then be inflated.
Abstract:
A tire inflation apparatus and method involves first evacuating a seated pneumatic tire via a vacuum pump and then inflating the tire with a purified, dried gas under pressure, such as pressurized nitrogen, without allowing any ambient air to reenter the evacuated tire. The apparatus includes a three way valve which attaches to the source of compressed dry gas, to the tire valve, and to the vacuum pump with a micron vacuum gauge provided for monitoring the state of vacuum within the evacuated tire.
Abstract:
Apparatus injects fluid such as sealing and balancing fluid into inflated tires, even two tires on a dual rim wheel, while on a vehicle. It seals to the valve stem so that the valve core can be unscrewed and retracted under pressure, providing an unobstructed fluid injection path before replacing the core without significant pressure loss. Tools for bending tire stems in situ facilitate apparatus installation. The method includes the steps of: sealing a valve assembly to the valve stem; sealing a valve core remover to the assembly; opening a valve of the assembly; passing a core engager through the valve and into the valve stem; engaging and unscrewing the core; allowing tire pressure to blow the core into the remover; closing the valve; removing the core remover; sealing a fluid dispenser to the assembly; opening the valve; dispensing the fluid; closing the valve; replacing the dispenser with the core remover; opening the valve; pushing the core into the stem; screwing the core into the stem; and removing the apparatus.
Abstract:
A method and apparatus for removing puncture sealing compositions from a tire, characterized by allowing air pressure to flow out of the tire via the valve, removing the tire valve, introducing a hose into the tire through the valve bore until the introduced hose end dips deeply into the sealing preparation contained in the tire and generating a pressure differential so that the sealing preparation is removed through the hose.
Abstract:
A compact device for sealingly storing, and subsequently delivering to the interior of a tire, a predetermined charge quantity of a tire leak sealant liquid includes a hollow liquid storage and transfer member, having an inlet fitting and an outlet fitting, within which the sealant liquid is disposed. When the hollow member is operatively interconnected between a pressurized air source and the tire's valve stem, pressurized air sequentially forces the entire sealant liquid charge volume into the tire and then flows into the tire through the storage and transfer member. Accordingly, the device may be utilized to repair and fully inflate a flat tire. A check valve structure incorporated in the device prevents fluid backflow through the storage and transfer member. The device may also be used to force other treatment liquids, such as a tire conditioner liquid, into the tire. In an alternate embodiment of the device, the storage and transfer member is filled with a refrigerant circuit treatment liquid and may be interconnected between a source of pressurized refrigerant and a refrigerant circuit fill valve to recharge the circuit and force the treatment liquid thereinto.
Abstract:
Apparatus is provided for use with a tractor or like vehicle. The apparatus is adapted to liquid ballast and inflate a tube within a wheel of the vehicle. The apparatus comprises inflation means which include a pump adapted to pressurize air or liquid to the inflation pressure of the tube. A reservoir is provided which is adapted to be filled with ballast. The apparatus includes a nozzle adapted to fit within the tube. The nozzle is adapted to be positioned to purge up to 100% of the fluid within the tube at ambient pressures. The apparatus also includes piping means connecting the pump to the nozzle, and the pump to the reservoir.
Abstract:
A traction device for a motor vehicle comprising a hose connecting the vehicle's exhaust pipe to an air pressure pump inlet. The outlet of the pump is detachably connected to the inlet valve of the vehicle's tire. An outlet valve for exiting cold air is connected to another hose communicating with a temperature gage and a pressure gage.
Abstract:
A simple venting device for trapped gas pockets in hydraulic systems is inserted through a small access passages, operated remotely, and removed completely. The device comprises a small diameter, closely wound coil spring which is pushed through guide means which is temporarily inserted in the access passage. The guide has a central passageway which directs the coil spring radially upward into the pocket so that with the guide properly positioned for depth and properly oriented, the coil spring can be pushed up into the top of the pocket to vent the same. By positioning sealing means around the free end of the guide, and using operating means, the spring and guide means are removed and the passage is sealed.
