An air control valve according to an embodiment of the present invention includes: a piston rod having a piston part on one lengthwise side thereof and an insertion part having an opposite side thereof; a valve body having a space at a central portion thereof, having a piston hole, into which the piston part of the piston rod is inserted, on one side of an inner surface of the space, having an insertion recess, into which the insertion part is inserted, on an opposite side of the inner surface of the space, and in which an inside of the insertion recess is connected to at least one discharge port; and an elastic member configured to elastically support the piston rod such that the insertion part of the piston rod is extracted from the insertion recess. The air supplied to the piston hole may be supplied from the space through the insertion recess and the discharge port by moving the piston rod by using a pressure of the air such that the insertion part is inserted into the insertion recess or extracted from the insertion recess. Accordingly, the air supplied to one side of a foreign substance discharge control valve and a compressor may be effectively controlled. 본 발명의 실시예에 따른 에어 제어밸브는 길이방향 일측에는 피스톤 부가 형성되고, 타측에는 삽입부가 형성되는 피스톤 로드, 중심부에는 공간이 형성되고, 상기 공간의 내면 일측으로 상기 피스톤 로드의 상기 피스톤 부가 삽입되는 피스톤홀이 형성되며, 상기 공간의 내면 타측으로 상기 삽입부가 삽입되는 삽입홈이 형성되고, 상기 삽입홈의 안쪽은 적어도 하나의 토출포트와 연결된 밸브바디, 및 상기 피스톤 로드의 상기 삽입부가 상기 삽입홈에서 인출되도록 상기 피스톤 로드를 탄성지지하는 탄성 부재를 포함하고, 상기 피스톤홀로 공급되는 에어의 압력에 의해서 상기 피스톤 로드를 움직여서, 상기 삽입부가 상기 삽입홈으로 삽입시키거나 상기 삽입부를 상기 삽입홈에서 인출하도록 하여, 상기 공간에서 상기 삽입홈과 상기 토출포트를 통해서 공급될 수 있다.
