HYDRAULIC ANTIVIBRATION DEVICE

摘要

Hydraulic Antivibration Device Disclosed is a hydraulic antivibration mount. The mount has an annular rubb er spring set in an outer metal casing, encasing an inner metal portion having a central mounting means. The outer metal casing is crimped over the flange of an end cap. Located with the end cap and retained within the crimped portion is a flexib le diaphragm. Also retained within the crimped portion is a damper plate dividi ng the interior of the mount into an upper chamber A and a lower chamber B to be filled with fluid. The damper plate is formed from an upper plate and a lower plate. The upper and lower plates form a flow channel between the two plates which extends at lea st partially around the circumference of the damper plate, the flow channel permitting communication between the upper and lower chamber. The upper plate has an opening communicating to the upper chamber with an integral tab extending from the opening into the flow channel to block the channel.
