Claims

[Scope of Claim for Utility Model Registration] (1) A valve cylinder 2 that hangs down from the fixed cap 1 and has continuous sliding surfaces 4 and 5 with different inner diameters and an air hole 28 above, and a large-diameter sliding surface at the lower end. A stem 1 that can be pushed down from the outside and is equipped with an upper piston 7 that moves up and down a surface 4.
0, a shoulder portion 15 forming a discharge valve 27 is provided at the contact portion with the stem 10 above the housing 9, and a liquid passageway opening from the lower surface to the upper surface of the large diameter shoulder portion is held in the large diameter portion 18 below the housing. a shaft portion 14; and the shaft portion 14
An elastic cylinder is fitted and fixed in a cap shape to the large diameter part 18 of the cylinder, and has a suction valve 24 on the end surface of the liquid passage on the upper surface of the shoulder part, and a lower piston 8 that moves up and down on a small diameter sliding surface on the outside thereof. 23 and a lower piston part 13 supported by a spring on a valve seat integral with the spray pump having a pressure accumulating structure. (2) A cut groove 19 is provided on the upper outer periphery of the large diameter portion 18 of the shaft, and a cut groove 19 is formed from the shoulder portion toward the shaft downward, and the cut groove 1 is formed from the lower end surface of the shaft.
9, and a communication portion 21 where the cut grooves 19 and the shaft recess 20 meet, as set forth in claim (1). (3) The elastic cylinder according to claim (1) of the utility model registration, which is an upwardly facing flange-shaped cylinder and has a lower piston 8 on the outer edge of the upper end, and has a partition wall and a center hole approximately in the middle of the internal hole of the cylinder.
