Abstract
An isolator assembly has a housing with a bore. A resilient bushing is positioned within the bore of the housing. The bushing has a lower isolator spring element, a central region and an upper isolator spring element, wherein the central region has a smaller cross sectional area than each of the lower and upper isolator spring elements. The bushing has a bore extending at least partially axially therethrough. The lower and upper isolator spring elements are supported within axially spaced apart portions of the housing. A vertical hanger pin is secured within the bore of the bushing and projects outwardly therefrom to facilitate mounting the isolator assembly to an exhaust system component.

An isolator assembly comprising:
- a housing having a bore;
- a resilient bushing having a lower isolator spring element, a central region and an upper isolator spring element, wherein the central region has a smaller cross sectional area than each of the lower and upper isolator spring elements, and wherein the resilient bushing has a bore extending at least partially axially therethrough;
- the lower and upper isolator spring elements being supported within axially spaced apart portions of the housing;
- and
- a hanger pin secured within the bore of the resilient bushing and projecting outwardly therefrom to facilitate mounting the isolator assembly to an exhaust system component.
The isolator assembly of 1, wherein the housing includes a plurality of cutouts forming windows for facilitating assembly of the resilient bushing into the housing.
A vertical hanger isolator assembly comprising:
- a housing having a bore;
- a resilient bushing having a lower isolator spring element, a central region and an upper isolator spring element, wherein the central region has a smaller cross sectional area than each of the lower and upper isolator spring elements, and wherein the resilient bushing has a bore extending at least partially axially therethrough;
- the upper isolator spring element being located within the housing at a first end of the housing, and concentric with the bore in the housing;
- the lower isolator spring element being located at a second end of the housing and concentric with the bore in the housing;
- the bore of the resilient bushing is axially aligned with the bore of the housing;
- and
- a stud or bolt disposed in the bore of the resilient bushing and extending through the upper isolator spring element, through the central region and at least partially into the lower isolator spring element.
