Compact vibration damper for a hermetic refrigerant compressor

Claim 1

A compact, offset center of gravity type vibration damper for the exhaust conduit of a refrigerant compressor, which damper comprises: an annular body of elastomeric material sized for encircling a portion of the conduit intermediate the ends thereof; and a unitary element having clamping and mass portions, said clamping portion being generally cylindrical, deformable, and having a longitudinal slot to permit clamping about said elastomeric body without requiring access to the ends of the conduit, and said mass portion being longitudinally extended and semi-cylindrical with the cylindrical center of curvature substantially coincident with the longitudinal axis of the conduit; whereby the center of gravity of said element is axially and radially offset from the point of attachment to said elastomeric body, and said damper is readily applied to the conduit.
