ABSTRACT:
A non-symmetrical circular row of oil inlets are located in a circular manifold surrounding a squeeze film space in a squeeze film damper. The oil inlets are directed radially inwardly from said manifold to open into the squeeze film space. Certain cluster of inlets provide higher oil pressure to the squeeze film space than other inlets. All inlets are equipped with automatically closing synthetic rubber check valves.
