<p>PURPOSE:To discharge liquid of two kinds under high pressure and that by regulating the ratio of flow correctly. CONSTITUTION:A drive piston 19 conducts the movement of reciprocation in a drive cylinder 17 on the basis of the changeover of a direction conversion flow passage changeover valve 16, and drives first and second feed/discharge pistons 25a, 25b. On the basis of the reciprocating movement of both the feed/ discharge pistons 25a, 25b, liquids sucked from first and second liquid storing containers 8a, 8b are discharged into first and second discharge pipes 9a, 9b. On the basis of the volumes of the operation of first and second check valves 34a, 34b and first and second connecting rods 26a, 26b, this discharge is carried out also in the case of respective feed/discharge pistons 25a, 25b being moved in either direction.</p> |
