Patent attributes
A vibration dampening mount assembly includes a housing, resilient material, a sleeve and a restricting structure. The resilient material is fixedly attached to an interior surface of the housing and defines a first chamber and a second chamber. The sleeve is disposed within the housing and is centrally attached to the resilient material. The restricting structure between the first chamber and the second chamber includes a first portion attached to the housing and a second portion attached to the sleeve. In response to movement of the sleeve relative to the housing, the second portion of the restricting structure moves relative to the first portion. The first portion and the second portion of the restricting structure define a fluid passageway therebetween. The cross-sectional area of the fluid passageway changes in response to movement of the second portion relative to the first portion.
