Abstract: front page image
(EN) In one aspect, a seal apparatus for use with a mandrel is disclosed that in one non-limiting embodiment contains a seal housing disposed about the mandrel, wherein the seal housing is spaced apart from the mandrel to form a seal gap, a seal member disposed between the seal housing and the mandrel, wherein the seal member is bonded to the seal housing and the seal member is formed from a first material, and a seal support disposed between the seal housing and the mandrel, wherein the seal support is formed from a second material, wherein the second material is stiffer than the first material, and the seal support extends across the seal gap in response to an energizing force applied to the seal support.
(FR) Selon un aspect, l'invention concerne un appareil de joint d'étanchéité destiné à être utilisé avec un mandrin et qui, dans un mode de réalisation non limitatif, contient un logement de joint d'étanchéité placé autour du mandrin. Le logement de joint d'étanchéité est espacé du mandrin pour former un espace d'étanchéité, un élément d'étanchéité est placé entre le logement de joint d'étanchéité et le mandrin, l'élément d'étanchéité étant lié au logement de joint d'étanchéité et étant fait d'un premier matériau ; et un support de joint d'étanchéité est placé entre le logement de joint d'étanchéité et le mandrin, le support de joint d'étanchéité étant fait d'un second matériau, plus rigide que le premier matériau, et le support de joint d'étanchéité s'étendant sur toute l'étendue de l'espace d'étanchéité en réponse à l'application d'une force de sollicitation sur le support de joint d'étanchéité.
