CONSTITUTION: Liquid substances such as epoxy, silicone, and urethane are input into one tank and another tank, a hardener is input to operate a pumping instrument. A primary piston(54) and a secondary piston(56) move upwardly and accordingly two different substances are introduced into each spool cylinder(46,48) via a suction port(38) of a cylinder block(52). Two liquid substances are filled around the circumference of face portions(32,34) on primary and secondary spool rods(28,30). Afterward, upon air introduction, an actuating plate(16) moves rightward and the spool rods intercept the pair of suction ports. When the primary and the secondary cylinders pressurize simultaneously, two liquid substances filled in the face portions of spool rods are discharged to a nozzle(42). Then, the substances are uniformly mixed to drain outside.
