ABSTRACT:
An annular element is disposed within an outer tubular member of an insulator device in a manner to surround a recessed elastomeric body interposed between the outer tubular member and an inner tubular member. A channel formed in the outer periphery of the annular element is closed by the outer tubular member to define a passage which fluidly intercommunicates chambers defined by the recesses formed in the elastomeric body. The channel is sufficiently long and robust as to ensure the desired vibration damping and working life of the unit.
