FLUID DAMPERS HAVING TEMPERATURE-DEPENDENT VISCOSITY COMPENSATION AND AUXILIARY POWER UNIT INLET SYSTEMS EMPLOYING THE SAME

摘要

Embodiments of a fluid damper are provided, as are embodiments of an Auxiliary Power Unit inlet system including a fluid damper. In one embodiment, the fluid damper includes a housing assembly containing first and second hydraulic chambers, which are fluidly coupled by way of a flow passage. A plunger is slidably disposed within the housing assembly and is moves through a range of translational positions in response to variations in damping fluid pressure when the fluid damper is filled with damping fluid. An annulus or other restricted flow path is fluidly coupled between the first and second hydraulic chambers and is at least partially defined by the flow passage and the plunger. The restricted flow path has at least one dimension, such as a length, that varies in conjunction with the translational position of the plunger.

1. A fluid damper configured to be filled with a damping fluid, the fluid damper comprising:
a housing assembly; first and second hydraulic chambers within the housing assembly; a flow passage fluidly coupling the first and second hydraulic chambers; a plunger slidably disposed within the housing assembly and movable through a range of translational positions in response to variations in the pressure of the damping fluid when the fluid damper is filled therewith; and a restricted flow path fluidly coupled between the first and second hydraulic chambers and at least partially defined by the flow passage and the plunger, the restricted flow path having at least one dimension that varies in conjunction with the translational position of the plunger.
