Claims

[Scope of Claim for Utility Model Registration] In a closed cartridge tank that is installed to automatically supply liquid to a device that uses liquid, a. a first flow path forming a liquid flow path; b a first valve inserted into the first flow path; c applying an elastic force to the first valve to close the first flow path; a first spring, d, having an interior molded integrally with the interior of the first valve, and having an interior formed integrally with the interior of the first valve, the first spring having an interior that is formed integrally with the interior of the first valve; an opening pipe, e; a second valve, which is constituted by the inside of this pipe and the inside of the first valve formed integrally with this pipe, and forms an air flow path between the inside of the tank body and the outside of the tank body; a flow path, f a second valve inserted into the second flow path, g a second spring that applies an elastic force to the second valve to close the second flow path, h connecting a refueling device When this occurs, the shape of the tip of the claw of the refueling device pushes up the second valve against the elastic force of the second spring to open the second flow path, and the shape of the side surface of the claw allows the second valve to open. 1
means for opening the first flow path by pushing up the first valve against the elastic force of the spring; means that is integrally connected to the claw part inside the first valve in a state where the valve is pushed up; road and the second above
means for connecting the first flow path to an inlet provided in the oil supply device while maintaining airtightness between the first flow path and the flow path; A closed cartridge tank characterized by comprising: means for causing air and surplus liquid to flow out from the discharge pipe.
