摘要：A portable air-operated apparatus for cleaning, flushing, and filling a liquidcooling system of an internal combustion engine. The apparatus has an air-operatedreciprocating piston pump assembly operable to agitate or sequentially move liquid inopposite directions and pump liquid into the cooling system. The pump assemblydelivers the liquid to a manifold connected to an input hose coupled to the liquid coolingsystem. A control valve connected to the manifold is operable to direct an externalsource of liquid under pressure to the manifold or connect a reservoir carried by theapparatus to the manifold. The manifold has a check valve for controlling one-wayforward flow of liquid from the pump to the input hose. A by-pass hose connects thecontrol valve and manifold to by-pass the check valve to allow reverse flow of liquid inthe input hose back to the pump assembly so that the pump assembly will effect asequential forward and reverse flow of liquid in the cooling system. The control valve isoperable to connect the reservoir to the manifold so that the cooling system can befilled by the operation of the pump assembly with liquid stored in the reservoir. A filterlocated in the reservoir filters liquid moved from the reservoir by the pump assembly tothe cooling system.
