Abstract: Provided is a self-sealing unit which has two films in a facing state, two end surfaces intersecting with the films, and a plurality of self-sealing valves. The self-sealing valves have diaphragm chambers which are formed by the films and valve bodies which move in accordance with displacement of the films and open/close flow paths. When viewed from a direction perpendicular to a plane to which the self-sealing unit is fixed, the length of a diagonal line connecting intersection points on sides of the diaphragm chambers is set to be longer than that of a diagonal line connecting intersection points on sides of the valve bodies.

Abstract: A liquid ejecting apparatus has a liquid-chamber, a fluid-chamber, a flexible member that includes a film and a first-seal-portion and that separates the liquid-chamber and the fluid-chamber, and a pressurizing section which supplies a fluid to the fluid-chamber to pressurize the flexible member toward the liquid-chamber. The fluid-chamber is configured such that a first-seal-portion being provided in the fluid-chamber and the first-seal-portion come into contact with each other to be partitioned into a first-fluid-chamber having an introduction port through which the fluid flows in and a-second-fluid-chamber. The pressurizing section converts, by the supply of the fluid to the fluid-chamber, a state of the fluid-chamber into a first-state in which the first-contact-portion and the first-seal-portion come into contact with each other or a second-state in which the contact between the first-contact portion and the first-seal-portion is released so that the first-fluid-chamber and the second-fluid-chamber communicate with each other.
