摘要

HYDRAULICALLY DAMPED ANTI-VIBRATION MOUNT WITH DYNAMIC RATE INHIBITOR 1. A hydraulically damped anti-vibration mount comprising: a flexible diaphragm (22), an outer metal casing (18), an annular rubber spring (20) and an inner metal portion (16), together defining a cavity filled with a fluid; a damper plate (24) dividing the cavity into an upper chamber (A) and a lower chamber (B) which are in fluid communication through a damper channel (26 located within the damper plate (24); and a cup-shaped bumper (34) attached to the inner metal portion (16) and extending axially inward into the upper chamber (A), having a radially outwardly extending flange (37) located at an end distal to the inner metal portion (16); and a flexible flap (38) extending radially outwardly from the flange (37) toward the outer metal casing (18).
