ABSTRACT:
A mushroom-shaped shield body, that is, a shield body having a configuration consisting of a back surface tapered section having its diameter successively increased towards the inside of an accumulator and a stem portion, is disposed coaxially at the inside end portion of a liquid feed/discharge port of the accumulator, and an inner surface tapered section is formed along the circumference of the liquid feed/discharge port opposed to the back surface tapered section of the shield body to form an annular liquid flow path between said back surface tapered section and said inner surface tapered section so that the direction of the liquid flow passing through this annular flow path may be directed along the inner wall surface of the vessel of the accumulator, whereby a diaphragm disposed within the accumulator can be deformed so as to conform to the inner wall surface of the vessel and thus the volume efficiency of the accumulator can be enhanced.
