A hermetic compressor including a plurality of shock mount units attached between the housing and a compressor unit disposed within the housing. Each shock mount unit includes a coil spring to damp vertical movement of the compressor unit with a U-shaped spring to damp horizontal movement of the compressor unit. The U-shaped spring is in sliding contact with a shock mount bracket attached between the coil spring and the housing so that lateral oscillations of the compressor unit and sound transmission through the housing are reduced.

Why it's free to use
- Filed January 24, 1994 and granted August 4, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 24, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 24, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
