Claims

[Claims for Utility Model Registration] 1. A pressure vessel divided into two parts by a flexible thin film pressure receiving body, one side of which is provided with a sealed chamber filled with gas, and the other chamber side communicates with the discharge side of the pump head. A pump head section is placed on the upper surface of a pressure tank provided with an introduction chamber, and a linear protrusion is provided on the thin film pressure receiving body, and when the thin film pressure receiving body approaches the inside of the introduction chamber of the pressure tank, a linear protrusion is provided on the pressure tank. An automatic pump characterized in that the linear protrusion faces the recessed portion. 2. In paragraph 1 of the claims for utility model registration, a part of the pressure tank projects outward to provide a mounting part for the pump head part, and the annular shape is provided in a recess formed on the inner side of the introduction chamber of the mounting part. An automatic pump characterized in that the protrusions are positioned so as to form a bridge.
