Abstract

PURPOSE: To prevent trapping of liquid in an accumulator, by reinforcing the bottom portion of a diaphragm shaped to conform to a liquid chamber by attaching ribs to the inside of the bottom portion of the diaphragm at the portion thereof facing an inlet-outlet port of liquid, so that the bottom portion may not be deformed until other portions of the diaphragm come into tight contact with the container.
CONSTITUTION: A container is constituted by a lower cup-like member a and an upper cup-like member b, and a diaphragm 5 is supported therein with its flange portion 7 being held between these two cup-like members a and b. The diaphragm 5 is shaped to conform to the lower cup-like member a, and its bottom is recessed upward at the portion thereof facing a liquid inlet-outlet port 3. The bottom portion of diaphragm 5 is reinforced by providing a plurality of ribs 6, for instance, radially along the inner surface, so that the bottom portion may not be deformed until other portions of diaphragm 5 come into tight contact with the lower cup-like member a. With such an arrangement, it is prevented that said other portions of diaphragm 5 is deformed prior to the bottom portion, if a fairly high suction force is acted at the portion of diaphragm 5, so that trapping of liquid can be prevented positively.
