ツキ弁間の流路に連通させた加減圧室と、該加減
圧室に設けたプランジヤー等の定量加減圧機構と
、該定量加減圧機構を連続駆動させる駆動手段と
を備えてなる小型定量送液ポンプにおいて、前記
両チエツキ弁間の流路に分岐路を設け、該分岐路
に開閉弁を介して前記加減圧機構の容量に比べて
充分に大きい容量の補助加減圧機構を連続させた
ことを特徴としてなる小型定量送液ポンプ。 A pair of check valves oriented in the same direction, a pressurization chamber that communicates with the flow path between the check valves, a quantitative pressurization mechanism such as a plunger installed in the pressurization chamber, and the constant pressurization mechanism are connected continuously. In a small metering liquid feeding pump comprising a driving means for driving, a branching path is provided in the flow path between the two check valves, and the branching path is provided with an on-off valve that is connected to a valve having a sufficient amount of water compared to the capacity of the pressure regulating mechanism. A compact metering liquid pump characterized by a continuous large-capacity auxiliary pressurization mechanism.
