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.

A vibration isolation assembly comprising a base, a plunger and an annulus of resilient material disposed between the base and plunger,
- the base having a pair of oppositely inclined, internal, tapered surfaces connected to each other and defining an opening though the base, the tapered surfaces of the base contacting corresponding external surfaces of the annulus,
- the opening having a first generally circular end and a second generally circular end, each of the tapered surfaces extending radially outward from one of the circular ends so that the opening through the base includes a generally circular cross section between the circular ends that has a larger diameter than the first circular end of the opening and the second circular end of the opening,
- the plunger having 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 engaging corresponding internal surfaces of the annulus.
