Abstract
A vane assembly and a snubber comprising the same are provided. The vane assembly comprises: a hub for mounting on a shaft of the snubber to rotate with the shaft about a snubber axis, the hub having an inner surface for mounting on the shaft and an outer surface with a vane mounting portion and a dam sealing portion; a vane removably secured to the hub to rotate with the hub about the snubber axis, the vane extending from the hub in a vane-vertical direction and defining at least a distal portion of an outer contour of the vane assembly, the vane having a hub facing surface for mounting to the vane mounting portion of the hub; and a seal assembly for providing a seal between a casing of the snubber and the vane assembly.

A snubber comprising:
- a casing having an internal cavity;
- a shaft extending through the casing and into the internal cavity;
- a vane assembly secured on the shaft within the internal cavity to rotate with the shaft about a snubber axis and through a vane-swept region within the internal cavity;
- a dam secured to the casing within the internal cavity and engaging the vane assembly such that the dam and the vane assembly divide the internal cavity into a first pressure chamber and a second pressure chamber;
- and
- an accumulator in fluid communication with the internal cavity, the accumulator housed completely within the casing.

A vane assembly for a snubber, the vane assembly comprising:
- a hub for mounting on a shaft of the snubber to rotate with the shaft about a snubber axis, the hub having an inner surface for mounting on the shaft and an outer surface with a vane extending radially outwardly from the outer surface;
- and
- a seal assembly for providing a seal between a casing of the snubber and the vane assembly.
