A hydraulic accumulator A to be removably attached to a support member includes a liquid chamber R2b having a predetermined volume even when no pressurized operating liquid is accumulated, and communicating with a liquid inflow port Pi and a liquid outflow port Po, which are disposed below the liquid chamber R2b. A liquid-chamber-R2b-side end of an outflow passageway So connecting the liquid chamber R2b and the liquid outflow port Po opens to an upper portion of the liquid chamber R2b. Further, an inflow passageway Si connecting the liquid chamber R2b and the liquid inflow port Pi is coaxially disposed within the outflow passageway So, and a liquid-chamber-R2b-side end of the inflow passageway Si opens to the upper portion of the liquid chamber R2b.
A hydraulic accumulator including a liquid chamber which is formed in the hydraulic accumulator and has a predetermined volume even when no pressurized operating liquid is accumulated, the liquid chamber communicating with a liquid inflow port and a liquid outflow port, and the liquid oufflow port being disposed below the liquid chamber, characterized in that a liquid-chamber-side end of an inflow passageway connecting the liquid chamber and the liquid inflow port opens to an upper portion of the liquid chamber, and a liquid-chamber-side end of an outflow passageway connecting the liquid chamber and the liquid outflow port opens to an upper portion of the liquid chamber, wherein the outflow passageway opens to the liquid chamber only at the liquid-chamber-side end thereof.
A hydraulic accumulator including a liquid chamber which is formed in the hydraulic accumulator and has a predetermined volume even when no pressurized operating liquid is accumulated, the liquid chamber communicating with a liquid inflow port and a liquid outflow port, and the liquid outflow port being disposed below the liquid chamber, characterized in that a liquid-chamber-side open end of an outflow passageway connecting the liquid chamber and the liquid outflow port is located above a liquid-chamber-side open end of an inflow passageway connecting the liquid chamber and the liquid inflow port, wherein the liquid-chamber-side open end of the outflow passageway opens to an upper portion of the liquid chamber.
A hydraulic accumulator including a liquid chamber which is formed in the hydraulic accumulator and has a predetermined volume even when no pressurized operating liquid is accumulated, the liquid chamber communicating with a liquid inflow port and a liquid outflow port, and the liquid outflow port being disposed below the liquid chamber, wherein a lower end portion of the hydraulic accumulator is removably attached to a support member having a supply port to be connected to the liquid inflow port and a discharge port to be connected to the liquid outflow port, characterized in that a liquid-chamber-side end of an inflow passageway connecting the liquid chamber and the liquid inflow port opens to an upper portion of the liquid chamber, and a liquid-chamber-side end of an outflow passageway connecting the liquid chamber and the liquid outflow port opens to an upper portion of the liquid chamber.
