ABSTRACT:
An axial thrust bearing having opposite support and load members and formed between the support and load members of a bearing cavity to which pressurized fluid is supplied. The cavity is surrounded by an axially movable floating seal ring disposed in a groove in one of the members. In the center of the cavity there is arranged a valve disc covering a vent passage in the support member, being axially movably supported by the load member. Resilient means are associated with the valve disc forcing it toward the support disc into its normal axial end position given by the load member such that during load peaks the load member is permitted to approach the support member beyond the normal position of the valve disc, while the valve disc is forced by the resilient means onto the vent opening to dampen the movement of the load member toward the support member.
