Title: Low cost accumulator device

Abstract: This invention relates to a low cost accumulator device, and more particularly to an accumulator wherein, at least in the oil port adjacent portions, the pressure vessel is formed by a spinning operation effected on a tubular blank. The device is characterized by a buffer member disposed adjacent the oil port and positioned to be deflected by the bladder in such manner as to protect the bladder from extrusion through the irregularities inherently formed as a result of the spinning operation.
