    摘要: A back-up ring to prevent damage to a packing ring disposed in a groove on an internal piston within a cylinder. The back-up ring has a folded portion with concave and a convex surfaces to prevent damage to the ring when it is unfolded to enlarge the ring for placement in the groove and re-folds to seat in the groove. In another embodiment, holes are disposed in the folded portion to relieve stress concentrations accompanying folding and unfolding of the back-up ring.

    摘要: The pressure vessel of a hydraulic accumulator comprises bowl-shaped body and lid members welded together edge to edge, lid member uppermost. A bowl-shaped diaphragm in the vessel having its concave surface facing up is supported by a rigid ring having a large diameter radially outer portion seated on an upwardly facing circumferential shoulder on the body member, near its rim. A smaller diameter radially inner portion of the ring is clinched over a bead around the edge of the diaphragm. The ring also has a frustoconical, upwardly tapering radially intermediate portion connecting its radially inner and outer portions, to hold the rim of the diaphragm at a high level in the vessel.

    摘要: Accumulator consisting of a container body and a lid body. In assembling, first the open portion of the bladder is attached to the open portion of the lid. Thereafter, the joint portions of the lid body and container body are welded. A guide ring connected to a bladder holding ring is placed at the inner face of the joint portion of the lid body and container main body, said guide ring is then bonded to the lid body and the bladder holding ring is applied to the bladder. With the bladder holding ring and container main body, the flange portion of the bladder is pressed against the inner wall of the container.
