Abstract

A gasket in a transport refrigeration system (TRS) and method of preventing corrosion in a compressor using a gasket. The gasket includes a body, where the body includes a fluid pass portion, and a flange that extends from the body. The body and the flange include a second layer between an outside first layer and a third layer. The second layer is a metal and the metal is a non-uniform thickness that extends across the flange and the body to deflect compression load distribution.

First claim

What is claimed is:

1 . A gasket, comprising:
a body, wherein the body includes a fluid pass portion; and a flange that extends from the body, wherein the body and flange includes:
a second layer between an outside first layer and a third layer, wherein the second layer is a metal,
wherein the metal is a non-uniform thickness that extends across the flange and the body to distribute compressor pressure.

2 . The gasket of claim 1 , wherein the non-uniform thickness includes a first thickness, a second thickness, and a third thickness.

3 . The gasket of claim 1 , wherein a grain direction associated with the first layer is perpendicular to a grain direction associated with the third layer.

4 . The gasket of claim 1 , wherein the body of the gasket is adjustable in length.

5 . The gasket of claim 1 , wherein the non-uniform thickness is a smooth transition from a first thickness to a second thickness and distributes a compression load.

6 . The gasket of claim 1 , wherein the metal is fine-blanked, coined, or embossed to form the non-uniform thickness.

7 . The gasket of claim 1 , wherein the metal is a contoured non-uniform thickness and includes solid steel.

8 . The gasket of claim 1 , wherein the flange includes a first flange and a second flange that extend from different portions of the body, and wherein the first flange includes a non-stick coating on a first surface, and the second flange includes the non-stick coating on a second surface.

9 . A gasket in a transport refrigeration unit (TRU), comprising:
a compressor; a body associated with the compressor, wherein the body includes a fluid pass portion; and a flange extending from the body, wherein the body and the flange includes:
a second layer between a first layer and a third layer, wherein the second layer is a metal,
wherein the metal is a first thickness in the body and a second thickness in the flange.

10 . The gasket of claim 9 , wherein the first layer and the second layer are oriented such that a grain direction of the first layer is perpendicular to a grain direction of the third layer.

11 . The gasket of claim 9 , wherein the metal is formed in a mesh pattern.

12 . The gasket of claim 9 , wherein the metal includes a third thickness in the flange.

13 . The gasket of claim 9 , wherein the second thickness in the flange enables deflections for a compression load distribution.

14 . The gasket of claim 9 , wherein the metal is of a mesh form, and the first and second layers are in contact through holes in the mesh form.

15 . A method for preventing corrosion in a compressor system, comprising:
attaching a gasket to a compressor, wherein the gasket has a non-uniform metal core thickness, and wherein the gasket includes a body with a fluid pass portion; discharging heat transfer fluid from the compressor, wherein the heat transfer fluid flows through the fluid pass portion of the body of the gasket; and distributing compressor pressure, created from the discharging, throughout the gasket via the non-uniform thickness.

16 . The method of claim 15 , further comprising decreasing leak paths along the body of the gasket via the metal core, wherein the metal core is a wire mesh.

17 . The method of claim 15 , further comprising forming the gasket to include different layers with different grain directions to deflect compressor pressure.
