Abstract

A pressure accumulator has an assembly 13 adapted to be mounted in the oil port of the pressure vessel of the accumulator. The oil port assembly 13 is inserted into the interior of the pressure vessel through an enlarged gas charging port. The oil port fitting 16 has an annular flange portion 19 sized to engage against the interior wall portion 14 of the vessel 10 surrounding the oil port to provide a metal to metal contact. Surrounding the flange portion 19 and spaced from the oil port 15, there is a radially extending ledge portion 20. An elastomeric gasket member 35 is bonded to the flange 19 and ledge 20. The gasket has a downwardly directed depending bead portion projecting below the ledge portion 20. When the oil port assembly is clamped in position in the oil port by tightening a nut 38, the bead portion is compressed against the vessel and a tight leakproof connection between the oil port assembly and the pressure vessel 10 is effected. <IMAGE>
