Title: FLUID MOUNT INCLUDING A PARTITIONLESS COMPENSATOR
Abstract:
A fluid mounting (20) for isolating or damping vibration between a vibrating member (21) and a structure (23). In one aspect, the fluid mounting (20) includes inner (22) and outer (24) members, a flexible element (26), first (28) and second (30) operating chambers, a fluid passageway (32) interconnecting operating chambers (28, 30), and a partitionless volume compensator (36) including a compensator chamber (38) separated into a gas-filled portion (40) and a fluid-filled portion (42). Notably, the chamber (38) is devoid of any separating barrier. At least one lock passage (44) interconnects the fluid-filled portion (42) with one of the first and second operating chambers (28, 30), and a working fluid (34). Preferably a bubble trap (46) focuses the bubbles into the lock passage (44). In another aspect, mounting (20) may include laminated shim construction and sloping profiles thereon prevent bubble trapping.
