ABSTRACT:
The present invention is directed to an accumulator device and method of making the same characterized in that the bladder support member is connected to the body of the pressure vessel by a resistance weld between relatively thin gauge portions of the vessel and the bladder support, the device being so constructed and arranged as to be susceptible of operation under high pressures notwithstanding the thin pressure vessel section as a result of the reinforcing effects of a cap member secured over the open end of the accumulator.
