載のスプリング付勢形ポン[Claims for Utility Model Registration] (1) A suction passage equipped with a suction valve and a discharge valve. A piston that increases or decreases the volume of a pump chamber that communicates with a discharge passage provided with the pump is biased in one direction by a sprig, and is actuated by being moved by a drive device against the biasing force of a spring. In the spring-biased pump, a cut valve is provided in the suction passage or the discharge passage to prevent fluid from flowing in a direction opposite to that blocked by the suction valve or the discharge valve, and the cut valve is closed to remove fluid from the pump chamber. An assembly characterized in that the piston can be assembled into the drive device while maintaining the piston in a displaced position against the spring biasing force by preventing fluid from flowing out or flowing into it. A spring-biased pump with improved attachment properties. (2) The spring biased pump according to claim 1, wherein the cut valve is provided at a portion where the suction passage or the discharge passage is bent into an L-shape. (3) The spring attachment according to claim 1, wherein the cut valve is provided with a push screw on the suction valve or the discharge valve to prevent the valve element from separating from the valve seat.
