Disclosed is an electromagnetic pump. The electromagnetic pump comprises: a holder unit having a space formed therein to communicate with an intake passage and an outtake passage; a first check valve which is mounted in the space and regulates a movement of a fluid discharged to the outtake passage from the space; a piston to reciprocate in the space; a second check valve which is mounted on the piston to form a fluid accommodation unit between the first check valve and the same, and regulates a movement of a fluid inputted into the space from the intake passage; a motor unit to press the piston towards the first check valve to move the piston; and an elastic member whose both ends come in contact with the first and the second check valve to press the second check valve in a direction in which the second check valve moves away from the first check valve.

    전자기 펌프에 관한 발명이 개시된다. 개시된 전자기 펌프는, 내부에 공간부가 형성되어 흡입유로 및 토출유로와 연통되는 홀더부와, 공간부에 결합되며, 공간부로부터 토출유로로 배출되는 유체의 이동을 단속하는 제1체크밸브와, 공간부에 왕복 이동 가능하게 구비되는 피스톤과, 피스톤에 결합되어 제1체크밸브와의 사이에 유체수용부를 형성하며, 흡입유로로부터 공간부로 입력되는 유체의 이동을 단속하는 제2체크밸브와, 피스톤을 제1체크밸브 측으로 가압하여 이동시키는 전동부와, 양단부가 각각 제1체크밸브와 제2체크밸브에 접하여, 제2체크밸브를 제1체크밸브에서 이격되는 방향으로 가압하는 탄성부재를 포함하는 것을 특징으로 한다.
