ABSTRACT:
An automatic device for replenishing the liquid oil and the like is composed of an oil container, a cap, an oil injecting seat, an oil blocking body, and a connection seat. The oil container is provided at the bottom thereof with a joint fastened therewith rotatably. The oil injecting is located in the joint and is provided at the bottom thereof with a cut. The connection seat is fastened at the top end thereof with the joint. When the oil consumption has reached an extent that the cut of the oil injecting seat and the oil level surface form therebetween a gap, the atmospheric air is drawn into the connection seat through which the atmospheric air flows into the joint via the gap, thereby resulting in an automatic replenishing of the oil. As soon as the gap is eliminated, the atmospheric air is kept out of the connection seat so as to bring about an end to the replenishing process of oil.
