Patent ID: 8069990

Claim:
A sealing gasket for mounting in a passage ( 5 ) of a support plate ( 4 ) to surround the end of a tubular-shaped filter element ( 3 ) provided with at least one fluid flow channel ( 3 1 ), the channel lying within a flow section Sc, the gasket being characterized in that it is made in the form of a sleeve: possessing a height h not less than the height hps of the passage ( 5 ) in the support plate ( 4 ); and presenting an overlap bore ( 15 ) for the filter element ( 3 ) defined between one end ( 16 ) of the sleeve and a shoulder ( 17 ) having a surface perpendicular to a surface of the overlap bore and which co-operates with the other end of the sleeve to define a channel bore ( 19 ) for the fluid, the shoulder ( 17 ) possessing a surface for acting as an abutment for the terminal portion of the filter element and presenting dimensions that are adapted to extend outside the flow section Sc so as to avoid impeding fluid circulation, the overlap bore ( 15 ) being provided with a groove ( 28 ) adjacent to the shoulder ( 17 ) in order to allow the gasket to creep, wherein the groove ( 28 ) presents a diameter dg and a height hg such that the ratio dg/dm lies in the range 1 to 1.5 and the ratio hg/hci lies in the range 0.2 to 1,with dm being the diameter of the filter element ( 3 ), and with hci being the height of the channel bore ( 19 ).
