PURPOSE:To supply fixed quantity in two functions at a high accuracy and smoothly by installing integrally and coaxially two plungers, large and small, for opening and closing the passages of large and small supply quantities and operating them with air pressure. CONSTITUTION:A large plunger 2 moves from a closing valve position to an opening valve position shown in two-point chain line by a stroke of S1 and at the opening valve position, and the end 16 of large diameter moves to an orifice 28 of large diameter moves to the inside of a large diameter liquid passage 12 to discharge liquid out of a large diameter orifice 28 to spots through a liquid supply inlet 19 and liquid passages 18 and 12. Likewise, a small plunger 3 moves by a stroke of S2, and its large diameter end 24 moves into a large diameter passage 21 inside a large plunger 2 to discharge liquid out of a small orifice 29 to spots through the liquid supply inlet 19, a liquid connecting inlet 27 and liquid passages 26 and 21. All the movements are controlled with air pressure and suck pack action is effected in reset transfer.
