TENSIONER WITH AXIAL SEAL
A tensioner having an axial seal comprising a base having a receiving portion, the receiving portion extending about a circumference of the base, a pivot arm pivotally engaged with the base, the receiving portion in continuous proximity to the pivot arm, a spring urging a movement of the pivot arm, and an axial seal engaged with the receiving portion, the axial seal comprising members extending in an axial direction (A-A), the members in sliding contact with a pivot arm surface.
1 . A tensioner having an axial seal comprising:
a base having a receiving portion, the receiving portion extending about a circumference of the base;
a pivot arm pivotally engaged with the base, the receiving portion in continuous proximity to the pivot arm;
a spring urging a movement of the pivot arm; and
an axial seal engaged with the receiving portion, the axial seal comprising members extending in an axial direction (A-A), the members in sliding contact with a pivot arm surface.
2 . The tensioner having an axial seal as in claim 1 , wherein the members comprise flexible bristles.
3 . The tensioner having an axial seal as in claim 1 , wherein the members comprise flexible planar members.
4 . The tensioner having an axial seal as in claim 1 , wherein the base comprises a shaft, the pivot arm journalled to the shaft.
5 . A tensioner having an axial seal comprising:
