ABSTRACT:
A fluid damper for controlling transverse orbital movement (14) of a non-rotating cylindrical body (12) is provided with a sealed, fluid filled reservoir (30) in fluid communication with a vent opening (24) disposed in a surrounding support member (10). A sized orifice (34) controls the volumetric flow rate of the damping fluid, maintaining an elevated average static fluid pressure in the annular volume (16) and resisting surge flow into the reservoir (30) through the vent (24) during the periodic occurrence of high fluid pressure in the annular volume (16) adjacent the vent opening (24).
