A sealing ring for use in connection with a filter bag assembly of a filter is disclosed. The sealing ring includes an annular body having an outer annular wall projecting from the body. The outer wall is flexible such that it can engage an adjacent surface of the filter in a liquid-tight manner for forming a seal between the surface and the sealing ring.

[ We claim:] [1.] A filter bag assembly adapted for use in filtering apparatus, comprising at least one filter bag; and a sealing ring having an annular body which includes a skirt attached to said at least one filter bag, said annular body having an annular support wall, which is sized and shaped so as to be supported on a supporting structure of the filtering apparatus, an outer annular wall, which projects substantially upwardly from said support wall, an inner annular wall, which projects substantially upwardly from said support wall, which is located radially inwardly from said outer wall and which is connected to said skirt, and an annular groove, which is formed between said inner and outer walls and which is delimited by said support wall, said outer wall being sized and shaped so as to engage an adjacent sealing surface of the filtering apparatus in a substantially fluid-tight manner, said support wall being sized and shaped so as to engage the supporting structure in a substantially fluid-tight manner, said outer wall being flexible such that it can flex radially outwardly in response toapplication of radially outward force to said outer wall from said groove, whereby said outer wall is engageable with the adjacent sealing surface in a fluid-tight manner, said outer wall being sized and shaped so as to flex radially outwardly in response to radially outward force applied to said outer wall by internal fluid pressure in the filtering apparatus, said inner wall being sized and shaped so as to be engaged by a cover of the filtering apparatus for urging said support wall in an axial direction against the supporting structure in response to application of the cover to the filtering apparatus, whereby a fluid-tight seal is formed between said support wall and the supporting structure, and said inner wall including at least one channel for permitting fluid communication between said groove and an interior of the filtering apparatus such that the internal fluid pressure in the filtering apparatus can be applied from the interior of the filtering apparatus to said outer wall through said at least one channel and said groove.
