A PRESSURE VESSEL Abstract of the Disclosure This invention relates to an inexpensive pressure vessel of the type which can be disposed of rather than being repaired once it fails. The pressure vessel includes a cylindrical housing having two chambers separated by a resilient bladder. One cham- ber is for housing a gas while the second is for housing a fluid such as hydraulic oil. The cylindrical housing contains a port at one end and is open at the opposite end. The end cap which contains a through port and a gas valve is insertable into the open end of the cylindrical housing and is welded thereto. This weld joint in conjunction with a seal formed by attaching the resilient bladder to the end cap, will positively seal the pres- sure vessel. The unique seal between the end cap, bladder and housing is such that it will not be thermally damaged by the welding process which seals the end cap to the cylindrical hous- ing.
