給装置。[Claims for Utility Model Registration] 1. A multiple plunger 4 is slidably inserted into the cylinder body 1, a plurality of plunger chambers 6 are formed between the cylinder body 1 and the multiple plunger 4, and each plunger In a multiple synchronized pressure liquid supply device configured by opening a pressure liquid inlet/outlet 8 in a chamber 6, a plurality of plungers 5a are formed into cylindrical shapes with different diameters and are arranged concentrically inside and outside with an annular space 6a apart. At the same time, the multiple plungers 4 are constructed by fixing each plunger 5a to the plunger base plate 7, and the plurality of plunger insertion holes 6b are formed into cylindrical holes having different diameters, and the annular wall 5b is spaced apart. The cylindrical body 1 is constructed by arranging the cylindrical plungers 5a concentrically inside and outside, and each cylindrical plunger 5a is inserted into each cylindrical plunger insertion hole 6b in a sealed and slidable manner, thereby forming a gap between the plunger insertion hole 6b and the annular space 6a. 1. A multiple synchronous pressure liquid supply device, characterized in that at least one of the two is configured as a plunger chamber. 2. The multiple synchronous pressure liquid supply device according to claim 1, wherein both the plunger insertion hole 6b and the annular space 6a are configured as a plunger chamber 6.
