Abstract: A damper system for a power cell includes a single-piece top damper element disposed on the power cell, a pair of middle damper elements disposed about a mid-portion of the power cell, and a single-piece bottom damper element that is formed from a material having Shore hardness in the range of about 90 A to 95 A. The middle damper elements are mutually identical in construction, and include interlocking features that are configured to allow a releasable engagement therebetween. The bottom damper element defines a central opening therein, and includes a base plate disposed about the central opening. The bottom damper element further includes appendages extending axially from a top side of the base plate, and a lateral projection extending radially inward from each of the appendages. The lateral projection is configured to abut a top side of a keel member defined at a bottom portion of the power cell.

Abstract: An enclosure for a power cell of a hydraulic hammer includes a single-piece hollow elongated body, a resilient cover, and multiple deformable plugs. The body includes a top flange, and an integrally formed polyhedral mid-portion. The mid-portion includes multiple sidewalls, and an end wall that is integral with a bottom end of the sidewalls. The sidewalls define a first sealing aperture, a second sealing aperture, and a pair of arcuate openings thereon. The resilient cover includes laterally disposed first and second portions that are configured to releasably engage with the body to cover a top portion and a bottom portion of the arcuate opening respectively. The deformable plugs are releasably engaged with the body at the first and second sealing apertures. The plugs include resilient members that co-operate with interfitting features located adjacent to the first and second sealing apertures of the body.
