Abstract

The apparatus for testing the spraying condition of fuel injection valves in Diesel engines for marine or other use comprises an oil pressure booster. This is composed of a high pressure chamber having check valves on opposite sides and a cylinder chamber having a piston for reciprocating plunger in the high pressure chamber. A fuel injection valve is connected to the high pressure chamber of the oil pressure booster and an oil feed pump feeds low pressure oil into the high pressure chamber and cylinder chamber of the oil pressure booster. A switching valve feeds oil from the oil feed pump alternately into the oil inlet-outlet ports on opposite sides of the cylinder chamber.
