## Abstract

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.

## Claims

### Claim 1

A compressor comprising:
a housing;
a motor compressor unit disposed within said housing, said motor compressor unit including a crankcase;
a shock mount bracket attached to said housing;
a plurality of shock mount units attached between said bracket and said crankcase, each said shock mount unit including a coil spring to damp vertical movement of said motor compressor unit and a flat spring to damp horizontal movement of said compressor unit, said flat spring always in sliding contact with said bracket, whereby lateral oscillations and sound transmission through the housing are reduced.

### Claim 2 (depends on 1)

The compressor of claim 1 in which said flat spring is U-shaped, and said coil spring is helical-shaped.

### Claim 3 (depends on 1)

The compressor of claim 1 in which said second spring includes two legs that slide on opposite sides of said bracket.

### Claim 4

A compressor comprising:
a housing;
a motor compressor unit disposed within said housing, said motor compressor unit having a suspension attachment connection;
a mounting bracket attached to said housing;
a coil spring having a first and second end, said first end attached to said mounting bracket;
an attachment stud interfit on said spring second end, said stud including a cylindrical attachment portion facing away from said spring second end, said cylindrical attachment portion attached to said suspension attachment connection;
a U-shaped spring having a base portion, said base portion having an opening, said attachment stud interfit through said base portion so that said U-shaped spring overfits said coil spring and slidably engages said mounting bracket.

### Claim 5 (depends on 4)

The compressor of claim 4 in which said second spring includes two legs that slide on opposite sides of said bracket.

### Claim 6 (depends on 4)

The compressor of claim 4 in which said suspension attachment connection is a blind bore within said motor compressor.
