Isolators enabling large rotation angle capabilities with highly restricted damper orifices

摘要

Embodiments of an isolator (10) are provided. In one embodiment, the isolator includes a damper housing (22) having a radially-extending partition wall (38) through which a central opening (30) is formed. First and second hydraulic chambers (56, 58) are located on opposing sides of the radially-extending partition wall and may be filled with a damping fluid. At least one restricted orifice (60) is formed through the damper housing and fluidly couples the first and second hydraulic chambers. The isolator further includes a damper piston (20), which extends through the central opening, which is exposed to the damping fluid when the first and second hydraulic chambers are filled therewith, and which is configured to translate along a working axis (12) with respect to the damper housing during operation of the isolator.
