摘要： A pressure accumulator for a hydraulic system includes a rigid container whose cavity contains a partition of pliable, resilient material which seals one compartment adjacent the bottom wall of the container from another compartment containing a gas under a pressure sufficient for expanding the partition into abutting engagement with the bottom wall when the fluid pressure in the one compartment equals atmospheric pressure. A passage outward from the one compartment through the bottom wall is shielded against insertion therein of any portion of the partition, and the resulting risk of injury to the partition, by a shielding member projecting from the bottom wall into the one compartment and having a frontal surface directed toward the other compartment. Its annular rim portion has a surface contiguously adjacent an annular portion of the bottom wall, and the two annular surface portions and the partition bound therebetween an annular space at atmospheric pressure in the one compartment. The passage of the bottom wall communicates with an orifice in the annular space.
