SEAL SLEEVE AND ASSEMBLY INCLUDING SUCH A SEAL SLEEVE

摘要

Seal sleeve and assembly including such a seal sleeve. A seal sleeve (10) having a seal sleeve wall (14) comprising a swellable polymer material having elastomeric properties so that the seal sleeve has non-swollen state and an expanded state, wherein the seal sleeve wall has a closed circumference that extends around a central longitudinal axis (A), the seal sleeve wall having a non-swollen thickness that is defined by the distance between an inner surface and an outer surface of the seal sleeve wall in the non-swollen state, the non-swollen thickness being less than the radial width of a circumferential space between an inner and an outer element that has to be closed off by the seal sleeve, wherein at least one of the end surfaces (14a, 14b, 252) extends in a plane that includes a sharp angle (a) with the longitudinal axis.

1. A seal sleeve (10) including:
a seal sleeve wall (14) comprising a swellable polymer material having elastomeric properties so that the seal sleeve has non-swollen state and an expanded state, the seal sleeve wall (14) having a closed circumference that extends around a central longitudinal axis (A) and that has a certain length in the direction of the central axis (A); the seal sleeve wall (14) having a non-swollen thickness that is defined by the distance between an inner surface and an outer surface of the seal sleeve wall (14) in the non-swollen state and having an expanded thickness that is defined by the distance between the inner surface and the outer surface of the seal sleeve wall (14) in the expanded state; and two free end surfaces (14a, 14b; 252);characterized in that at least one of the end surfaces (14a, 14b; 252) extends in a plane (P2, P3) that includes a sharp angle (α) with the longitudinal axis (A).
