## Abstract

A baffle for use in a refrigerator apparatus comprises a baffle plate comprising a first and a second opposing sides attached to an inner surface of the refrigerator apparatus, a baffle seal plate attached along a third side of the baffle plate, the baffle plate seal plate attached to the inner surface of the refrigerator apparatus.

## Claims

### Claim 1

An economizer assembly, comprising:
an economizer chamber having an outlet to a compressor, a liquid outlet and an inlet; and
a baffle structure positioned between said outlet to said compressor and said liquid outlet to dampen at least one flow pulsation from said outlet to said compressor.

### Claim 2

A refrigerator component, comprising:
a chamber having a first port communicated with a compressor and a second port having a float valve; and
a baffle assembly positioned between the first port and the second port, whereby the baffle assembly protects the second port from pulsations entering the chamber from the first port.

### Claim 3 (depends on 2)

The apparatus of claim 2, wherein the baffle assembly comprises a baffle plate having first and second opposing sides attached to an inner surface of said chamber; and a baffle seal plate attached along a third side of said baffle plate, said baffle seal plate attached to said inner surface of said chamber.

### Claim 4 (depends on 3)

The apparatus of claim 3 wherein said baffle plate, said baffle seal plate, and said inner surface define a concavity.

### Claim 5 (depends on 4)

The apparatus of claim 4 wherein a discharge pipe extends from a portion of said inner surface forming said concavity.

### Claim 6 (depends on 4)

The apparatus of claim 4 wherein said baffle plate is welded to said inner surface.

### Claim 7 (depends on 4)

The apparatus of claim 4 wherein said baffle seal plate is welded to said baffle plate.

### Claim 8 (depends on 4)

The apparatus of claim 4 wherein said baffle seal plate is welded to said inner surface.

### Claim 9 (depends on 3)

The apparatus of claim 3 wherein said refrigerator component comprises an economizer.
