The invention relates to a dosing apparatus which injects liquid in equal quantity dosing, and specifically an upper disk (11) and a lower disk (21) are connected with a cylinder (30) used to pump liquid. . A conical protrusion part (12) which is wider at the top and narrower at the bottom is formed at the bottom of the upper disk. A conical recessed part (22) which is wider at the top and narrower at the bottom is formed at the top of the lower disk. A plurality of through-holes (23) for communicating a space between the protrusion part (12) and the recessed part (22) with the outside are formed. The liquid transferred by the cylinder (30) is dosed in equal quantity through the through-holes (23). The apparatus can improve the precision of a liquid dosing apparatus, and improve the precision of dosing when liquid is high in viscosity or half-liquid and half-solid phase. |
