ABSTRACT:
The liquid storage apparatus includes: a liquid storage chamber which is constituted by a flexible bag member and stores liquid; an exterior container which has walls constituted by a shape memory member and has a hermetically sealed space in which the liquid storage chamber is disposed, the shape memory member extending and contracting freely at temperatures not greater than a transformation temperature and recovering a memorized shape at temperatures not less than a shape recovery temperature; a forcing member which applies a contraction force to the walls of the exterior container in a direction in which the walls contract; and a temperature adjuster which adjusts a temperature of the shape memory member directly or indirectly so as to control a ratio of a portion of the shape memory member having temperatures not greater than the transformation temperature and deformed to a contracted shape by the contraction force of the forcing member and a ratio of a portion of the shape memory member having temperatures not less than the shape recovery temperature and recovering the memorized shape more extended than the contracted shape, so that a pressure in the liquid storage chamber is changed depending on a volume change of the exterior container due to deformation of the shape memory member.
