Patent

CA 2246809

A rotary ball valve assembly and method for forming utilizes a compression spring subjected to a non-torsional, axially directed compressive force to urge an annular seal (66) into sealing engagement with a rotatable ball and, while so subjected, inwardly deforming a tubular member attached to the housing by an electromagnetic force to form an annular abutment (76) retaining said compression spring.

L'invention a trait à un ensemble clapet à bille rotatif ainsi qu'à son procédé de fabrication au titre duquel on utilise un ressort à pression soumis à une force de compression sans torsion et dirigée axialement afin de mettre un joint annulaire (66) en contact hermétique avec une bille susceptible de tourner. Lorsque le ressort est soumis à la force susmentionnée, on fait alors se déformer vers l'intérieur un élément tubulaire fixé au logement au moyen d'une force électromagnétique afin de constituer une butée annulaire (76) retenant le ressort à pression.
