Abstract

A hydraulic power unit that uses a quantity of media within a cavity adjacent to and surrounding a hydraulic assembly in the housing of the hydraulic power unit to reduce the overall noise of the unit. Additionally, the cavity either seals the media from the moving parts of the hydraulic assembly or isolates the media from the moving parts of the hydraulic assembly to ensure damage to the hydraulic assembly does not result.
