Abstract:
1. A method of guiding fluid material to dispenser by using a discharge control apparatus for discharging the fluid material to the dispenser, the discharge control apparatus comprising: a cylindrical injection side portion having an injection chamber to which the fluid material pressurized by a compressed air is supplied, and having a cylindrical inner surface forming an outer valve seating surface which is continuous from the injection chamber; a storage container which communicates with the injection chamber, the fluid material being accommodated in the storage container; a partition member which is cylindrical and arranged on the inside of the outer valve seating surface in a radial direction so as to face with the outer valve seating surface, and partitions an internal space into a discharge chamber formed on the inside of the partition member and an annular feed chamber formed on the outside of the partition member; an inner valve seating surface provided to the tip end of the partition member, wherein a valve chamber is formed between the inner valve seating surface and the outer valve seating surface; a discharge control block formed with a control flow path which is connected to the feed chamber, wherein the volume of the control flow path is changed by a discharge rod; discharging means provided to the discharge control block to reciprocate the discharge rod; and a valve element having a base portion which is arranged in the valve chamber, and opens and closes an inner flow path formed between the inner valve seating surface and the base portion of the valve element, and an annular flange portion which is integrally formed with the base portion, and opens and closes an outer flow path formed between the annular flange portion and the outer valve seating surface with elastic deformation, wherein the flow path switching valve has: the compressed air is continuously applied to the storage container when the flow path switching valve performs the discharge operation and the filling operation, and used to supply the pressurized fluid material to the injection chamber from the storage container, the method comprising:
