A compact, highly portable, multi-mode fluid injection system able to reach difficult to access places to efficiently service a variety of diameter pipes, tubing and related components. The system comprises a tank having a first port which allows access to the tank's upper contents and a second port which allows access to the tank's lower contents, a means for introducing liquid into the tank, a hand pump built into the tank to pressurize the tank and its contents, one or more applicators, and flexible hoses which connect the applicators to the first and/or second port to supply the applicators with the tank's contents. The system is capable of producing, alternatively, pressurized liquid or gas without an independently powered air compressor or consumable gas cartridges, and without having to empty and/or fill the tank. An onboard means for stowing the hose conduits, an injection gun applicator having a small travel-high flow valve with adjustable accumulation chamber, and applicators having stiff-flexible tips and tip extensions are also described.
A multi-mode fluid injection system comprising a single chamber tank, an aperture for introducing liquid and gas contents into said tank, a pump means to supply said liquid and gas contents of said tank with pressure, a first port allowing access to the gas phase contents located in upper portion of said tank, a second port allowing access to the liquid phase contents located in the lower portion of said tank, one or more applicators, and flexible hoses which connect said applicators to said ports, wherein said hoses with applicators may be attached to one, the other, or both of said ports and wherein said hoses supply said applicators, alternatively, with the tank's gas and liquid contents when said contents are under pressure.
A fluid injection system comprising a tank having at least one port allowing access to the tank's contents, a means for introducing fluid into said tank, a pump means to supply said tank contents with pressure, one or more applicators, flexible hoses which connect said applicators to said ports and serve to supply said applicators with the tank's contents when said contents are under pressure, and a concave lip that projects outward and upward from the base of said tank, whereby said lip function as a secondary reservoir against tank leaks and spills while increases tank stability when the system is in use, and whereby said lip function as an onboard means for stowing said supply hoses when said system is not in use.
