ABSTRACT:
A vibration isolation assembly comprises a base, a plunger and an annulus of resilient material between the base and plunger. The base has a pair of oppositely inclined, internal, tapered surfaces connected to each other which define an opening though the base. The tapered surfaces of the base contact corresponding external surfaces of the annulus. The plunger has an inclined surface substantially parallel to one of the internal surfaces and a second surface within the opening and facing the pair of tapered surfaces. The inclined surface and the second surface of the plunger engage corresponding internal surfaces of the annulus. In this device vibration creates a load on the annulus which is entirely compressive, or nearly so.
