Abstract
A SDHV damper assembly and methods to assemble and install the SDHV damper assembly are disclosed. The SDHV damper assembly includes a first damper housing half comprising a substantially cylindrical tube having a first open end and a second open end. The SDHV damper assembly further includes a second damper housing half comprising a substantially cylindrical tube having a first open end and a second open end. The first open end of the second damper housing half is joined to the first open end of the first damper housing half to form an assembled damper housing. A recess is formed in the damper housing either diametrically or longitudinally. The expandable damper member is received within the recess and expands to restrict flow in the damper housing and retracts to allow laminar flow through the damper housing.
